It is during this "period of plasticity," which is precisely controllable, that gypsum can be molded, shaped, or cast. As shown in the chart above, the strength of the gypsum mass can be controlled by varying the amount of water added. 1 As seen through a microscope--water has been added to gypsum piaster, and the hardening or setting action has begun. 2 Tiny crystalline needles have started to grow and interlace as the plaster re-combines chemically with the water. 3 Brilliant as jewels, crystals are re-forming into stone of controllable hardness, density, and strength. When you see finely ground gypsum plaster pour out of a bag, you might wonder what characteristic it possesses that--given water and a little time--the plaster sets into a material of rock-like hardness. Well might you wonder, for it is a rare characteristic among minerals, the "ability to remember"--a characteristic that has been utilized for at least 5,000 years, as gypsum has served the artists and craftsmen, the architects and builders of many civilizations. What gypsum plaster seems to remember is that it was originally stone. In processing, it is crushed and ground to powdery fineness, then heated to drive off water with which it is chemically combined. When water is added to gypsum plaster, however, it "remembers"-- and returns once again to a rock-like state. Only now, of course, it has been shaped into a useful form--into a delicate mold, perhaps, or the roof deck of a building, or one of the many other gypsum products described in this book. i.i ii BB019 0472 lape things -M ) come The aircraft and automotive industries stand out among the many, large and small, that have long recognized the advantages of gypsum plasters for pattern-making, non-ferrous metal casting, and, more recently, for the tooling of plastics. As a pioneer in developing better tooling methods. United States Gypsum is today the leading manufacturer of a full line of industrial plasters. Each of these plasters is suited to a basic tooling technique. Each has been specially formulated to meet specific requirements. All have two particularly desirable advantages--the extraordinary ease and the extreme accuracy with which they can reproduce a shape, no matter how complex or delicate it may be. Thus, patterns and models are completed quickly and economically; and if modifications are needed later, they are easily achieved. The investment in tools, equipment, and inventory is relatively small. It is this combination of advantages, found only in gypsum plasters, that makes them the preferred materials today for the shaping of things still to come--tomorrow. oppositc page: The full-scale model of an aircraft fuselage section was made in one-third the time required by wood pattern-making methods. The section was built up rapidly with a series of templates, which were filled with plaster. Simple screeding then finished the surface to specified accuracy. Curves and contours like this can be made to a tolerance of plus or minus .005 of an inch. above: Whether for massive airliners or for intricate art objects, craftsmen, like the one shown, can create original patterns of full-size models in infinite detail, easily and economically, with one of the industrial plasters in U.S.G.'s complete line. lift: Aluminum molds for giant tractor tires, match plates, core boxes, stamping, and forming dies--all cast in molds of gypsum--demonstrate industry's wide acceptance of this material. As parts emerge from the mold, they are usually so smooth and clean that no finishing is necessary. Gypsum for plastics tooling lower left: Hydrocal*, Ultracal*, and other U.S.G. industrial plasters have made significant contributions to the rapid growth of the plastics industry. For example, the plastic piece in the picture-- a washing compartment of a home laundry--was vacuum-formed over an ULTRACAL model. This particular gypsum plaster was selected because of the ease, speed, and low cost it offered in making the original model. 'HYDROCAL and ULTRACAL ate trademarks Reo. U. S.

BB019 0474 for delicate chinaware or giant industrial insulators controllable absorption, or the ability to ''de-water" a fluid mass, is the key to the growing popularity of gypsum molds. To understand this unique characteristic, a gypsum plaster mold should be visualized as a three-dimensional rigid sponge. Like a sponge, the mold will absorb water from a fluid mass, but its peculiar pore structure makes it possible to regulate the amount and rate of this absorption. Since this pore space can be controlled, the density or porosity of a gypsum mold can be adjusted to the requirements for molding products as varied as delicate chinaware and huge industrial insulators. This controllable absorption permits the forming of simple or complex objects from clay, latex, refractories, abrasives--from almost any fluid mass that can be shaped by casting, jiggering or pressing. As early as 1915, U.S.G. introduced its first gypsum plaster specifically designed for ceramic processes. The Company now offers a complete line of such plasters, backed by years of technological experience to meet the multiple requirements of the ceramic industry. O CNJJ 6roaa opposite pace: American chinawafe now ranks with the world's finest in durability, quality, and beauty. The classic example shown is Haviland ware, created from original models and molds of U.S.G. plaster: left: This picture shows a six-foot porcelain housing for a 300-KV circu breaker that was formed in a U.S.G. plaster mold. Because of their weight and size, industrial insulators are cast in plaster molds reinforced with steel rods. Molds for this automatic jigger must be strong, uniform, and accurate to permit the high degree of mechanization required by American ceramic plants to compete with foreign producers. Molds made of U.S.G. pottery plaster fulfill these requirements. A typical production line in an American sanitary ware plant. The use of molds made of U.S.G. plaster, with their uniform quality and exceptional durability, makes possible mass production of bathroom and lavatory equipment at low cost. This is how latex toys are stripped from multiple cavity molds of U.S.G. plaster. Because of the speed and economy of this process, American-made rubber toys and novelties of all types are well designed and attractive--yet mass produced. BB019 0476 gypsum as a chemical... Cuu^dL fouhdL f CxAbJULlAL* c^i- /kdjju/Ls above: Typical feeding equipment used to introduce gypsum rock into Portland cement clinker before grinding. center: In the manufacture of glass containers, gypsum, with its high sulfate content, is replacing salt cake and barium sulfate in clarifying glass. A crystalline compound of calcium, sulfur, and water of hydration (CaSC>4*2H20), gypsum as a chemical has many important uses in widely varied fields. In the manufacture of portland cement, for example, it is essential in the control of set; in the brewing industry, it is used as a clarifier. Under the name of land plaster, gypsum has been used in soil treatment for centuries. Today it is finding ever-increasing application as a soil conditioner and source of calcium and sulfur; millions of acres of previously alkali soils have been made productive with gypsum. Because of the ability of one of the forms of calcium sulfate to absorb water, it is widely used in the drying of gases. Being non-toxic and readily soluble, it has a myriad of uses in the food industry, too--as in canning, where it helps keep vegetables firm. With the constant advance of research and technology in gypsum, more and more uses are being discovered for this abundant and versatile mineral. It is already recognized as a valuable sulfur reserve, which is important because of the diminishing supply of this element. It is possible that gypsum will someday become a major raw material in the production of sulfuric acid, one of the most essential chemicals. below: Gypsum aids agriculture as is shown in this picture. The peanut plant at the left was grown in calcium-deficient soil. The plant at the right flourished in soil treated with gypsum. Besides supplying neutral calcium and sulfur, gypsum improves soil structure, neutralizes alkali soils, corrects high-sodium irrigation water, conserves nitrogen In manure, and clears muddy ponds. MVSiI B B O IV 0 4 7 7 lime a basic chemical in many industries In consumption, lime today ranks second only to sulfuric acid as a basic chemical. Many chemical and industrial processes make use of lime because of its chemical composition or for neutralization, coagulation or precipitation. Lime is almost indispensable in the metallurgical field. It is widely used in making paper and insecticides. It purifies and softens water, neutralizes noxious trade wastes and municipal sewage. In the dairy, sugar, gelatin, baking, and fruit industries, lime has many other applications. U.S.G. produces dolomitic lime at Genoa, Ohio. High-calcium lime is produced at New Braunfels, Texas and at Farnams, Massachusetts. Industries within the shipping areas of these plants are supplied with the various types of lime they require. To architects, engineers, and builders, gypsum has long been synonymous with fire-protection. Its role as a fire-fighter is more significant today than at any other period in history, as adequate fire-safety is sought for millions of people, their properties, and their possessions. Gypsum roof decks will not support combustion. Further, they have so much ability to withstand intense heat that the likelihood of roof failure in event of fire is almost negligible. As a result, insurance rates for buildings with incombustible gypsum roof decks are usually substantially lower; personnel safety is greatly increased; and the possibility of loss of plants, inventory, and BB019 0479 equipment,'as wdll as the sales position and establishment which go with them, is greatly decreased. Because Gypsum is so resistant to fire, more construction men, than ever before, are considering and specifying incombustible gypsum roof decks. They are doing this to provide the additional fire-safety so essential in buildings where.......... conventional fire-stops cannot be used. The modern plant of A. B. Dick Company, (shown below), with its poured gypsum roof deck, is an example of this trend, as are the thousands of other factories, schools, stores, warehouses, and institutions across the nation which have roof decks The heat from this blowtorch cannot be felt until the ice is melted. Exposed to fire, gypsum performs in much the same way. The unexposed surface remains relatively cool until its chemically combined water is driven off in the form of steam. This is an extremely slow process, requiring a full hour for heat of 1700 F. to penetrate a one-inch thickness of ' gypsum to a harmful degree. * Thus, gypsum is the mineral with a "built-in fire-protection system," a 4 unique physical characteristic that makes it incombustible--without equal as a fire proof material for roof deck construction. BB019 0480 M&hMb**4fcbh;, od&jjhihlc, bor'&wfj As America's schools are built, enlarged, modernized--it is of vital importance that they be given the utmost in fire protection. Materials and methods of construction must also be adaptable to modern design with its emphasis on economy and expandability. Pyrofill Gypsum Concrete meets all these requirements. below: Pyrofill Gypsum Roof Deck was'used for the extensive addition to this school at Grosse Point Woods, Michigan. In the architectural model shown, note how successfully the new contemporary buildings blend with the traditional design of the old. Pyrofill* .. the essential component of modern poured roof decks BB019 0481 T.M. Rea. U.S. Pet. Ott. When mixed with water, PYROFILL Gypsum Concrete can be pumped from ground level to roof level. As seen here, it flows freely through a hose and quickly covers the formboard, sub-purlins, and steel reinforcing mesh. The resulting slab sets hard and strong enough to walk on in about 15 minutes, so there is no need for costly planking and scaffolding. Because Pyrofill Gypsum Concrete can be poured rapidly, a typical 12-man crew can often finish up to 30,000 sq. ft. of roof area in a day. The roof deck is ready for the roof covering as soon as the PYROFILL sets. Ordinary inclement weather does not affect PYROFILL. Thus, the building is quickly "under roof." Interior work can be started and finished sooner, which means that buildings are ready for occupancy ahead of the schedule that would be required for materials with longer setting and curing times. Pyrofill Roof Decks Fear No Fire! Monolithic, joint-free, steel-reinforced-- a Pyrofill deck forms a positive barrier to heat and flame. It also imparts excellent lateral rigidity to the roof structure. The adaptability of Pyrofill to flat, curved, or pitched roofs offers broad freedom of design to architects and structural engineers. Since it can be finished in just a few days, a Pyrofill Roof Deck effects substantial savings in time and money. This modem roof deck construction is available through a nation-wide group of selected independent contractor organizations that specialize in pouring U.S.G. Pyrofill Gypsum Roof Decks. Administered by competent, responsible businessmen, each of these organizations operates modern equipment manned by skilled personnel. BB019 0482 /*: PYROFILL Gypsum Roof Deck, chosen for this modern building of The Armour iratories, has also been specified for the buildings of many other leading >rican companies, including: International Harvester Company, The Goodyear & Rubber Company, Inc., Sears, Roebuck and Co., Westinghouse Electric >., R.

EBaaSSEBSKPi BB019 0483 . formbo.ards of varied types increase the utility of Pyrofill top RifiHT: Formboards are the base materials over which Pyrofill Gypsum Concrete is poured to create the complete roof deck. When incombustibility at minimum cost is the major requirement, SHEETROCK* Gypsum Formboard is used. Fireproof SHEETROCK is available in large panels that are easily installed. Because its exposed surface is hard and smooth, light-colored SHEETROCK forms an attractive ceiling with good light reflection. ' If further decoration is desired, it can be painted with brush, roller, or spray equipment. center right: For effective sound control and pleasing beauty, U.S.G. Acoustical Formboard is preferred. Its unique slotted pattern permits a wide range of interesting ceiling designs to complement the contemporary architecture of today's schools, churches, auditoriums, and shopping centers. It can be painted repeatedly without noticeable loss of noise reduction qualities. lower right: This new formboard, called Pyroform*, is the latest product of U.S.G.'s constant research to improve roof deck construction. Specifically developed to be used with Pyrofill, it consists of millions of tiny mineral fiber filaments separated by minute air spaces. Thus, in one material are offered the outstanding advantages of incombustibility, thermal insulation, and sound absorption. In addition, the under surface of PYROFORM may be left exposed as the finished ceiling. T.M. Ra. U.S. Pt. OH. BB019 0484 roof decks of pre-cast gypsum planks In order to extend the advantages of gypsum to other types of roof deck construction, U.S.G. manufactures Metal Edge Gypsum Plank which differs from poured Pyrofill in that it is a dry unit system. No special skills are required to erect the units which can be installed in any kind of weather in which it is possible for men to work. The planks are 10 feet long, 15 inches wide, and 2 inches thick. As shown in the photo at right, all four edges are reinforced with heavy gauge, galvanized sheet steel formed into interlocking tongues and grooves. Strength and rigidity are further increased by specially designed steel reinforcing mats imbedded in each plank during manufacture. USG* Metal Edge Gypsum Plank is incombustible, and particularly adaptable to either flat or pitched roof surfaces. High light reflectance makes the underside suitable for finished ceilings. T.M. Reg.

USG* Steel Roof Decks are cold rolled from high quality carbon steel, with a rib design specially engineered to take advantage of the inherent strength of the metal. They are prime painted and pre-formed to provide edge interlocks for ready installation upon delivery to the job site. In addition to strength and speedy erection, USG Steel Roof Decks offer economy, good appearance, and easy maintenance.

Often the only difference between order and confusion is the effective control of sound and space that can be achieved with acoustical ceilings and movable walls. Ceilings of U.S.G. Acoustical Tile, either of incombustible mineral fiber or of wood fiber, reduce nerve-wracking noise as they beautify a room. USG * Movable Partitions create areas of needed privacy at reasonable cost.

Called Linea, it is notable for its classic sculptured lines. At right is the often-imitated fissured pattern of regular Acoustone. Closely resembling fine Travertine marble, it creates a singularly attractive ceiling. Other distinctive advantages of Acoustone are paintability, cleanability, durability, and high light reflectivity. These features, along with its beauty and efficiency, have gained wide acceptance for Acoustone in industrial, commercial, and institutional buildings. T.M. Roo. U.S. Pat.

G. expanded metals Those who design, make, and market America's products are finding that USG * Expanded Metal is broadening their horizons in many directions. Of its numerous uses in manufacturing plants, personnel safety and machinery protection stand out as perhaps the most important. Enclosures, ventilator panels, filter screens, and sorting bins are additional examples of its utility. In the heavier gauges known as Grate-X* Expanded Metal Grating, it provides sure footing on walkways, stairs, platforms, and industrial flooring. In the fields of product design, architecture, and display, the potential of USG Expanded Metal is virtually unlimited. Furniture, novelties, housewares, partitions, ceilings, decorative trim--these are but a few of the imaginative uses already found for this versatile product. USG Expanded Metal is cold drawn from a solid metal sheet resulting in a product of greater rigidity than the original sheet. Carbon steel or aluminum and, in some meshes, stainless steel are used. The open mesh pattern not only permits free passage of light and air, but also results in less weight, for important savings in shipping and handling costs. Other advantages include: attractive appearance, easy fabrication and welding, easy cutting without raveling, and ready paintability by accepted industrial methods. USG Expanded Metal is available in regular expanded design; or in a flattened pattern, if level surfaces are desired. r.M. Rl-<7. U S. Pal.

These new and exclusive patterns now join long-popular Expand-X*, in traditional diamond mesh, to open new avenues of expression for those concerned with the design, manufacture, and sale of products for better living. USG Expanded Metal has varied uses in many fields. It is used in architectural design and interior decoration. Industrial design, product engineering, and advertising displays find many places for it; and, manufacturing, transportation, and farming benefit by using it. USG Expanded Metal will be used in many, many other ways as imaginative minds discover its exciting possibilities! T.M. Reo. U.S. Pal.

Note how gracefully the single sheet of RONDO forms both the chair seat and back. BB019 0496 GRATE-X, another USG Expanded Metal, is especially suitable for industrial walkways and flooring, as it offers exceptional strength and sure traction underfoot. It is easy to maintain, and its "transparency" improves lighting conditions as well as air circulation. Specially designed U.S.G. welded steel grating has broad application throughout the railroad industry. Its non-skid surface makes it ideal for freight car running boards and brake steps. Duron? the lardboard ;hat mproves >n A^ood .M. ReQ. U.S. Pat. Oft. 4 Due to the natural grain structure of wood, (see the photomicrograph above left), it is subject to splintering, face-checking, splitting and warping. Sheets of Duron, on the other hand, while retaining the desirable characteristics of wood, do not have these disadvantages. The wood from which Duron is made is first reduced to fibers. Further processing rearranges these fibers, (see photomicrograph above right), and finally compresses them into stable, homogeneous sheets of hardboard. Duron Hardboard has an important extra feature--it is smooth on both sides, so either or both faces can be finished as desired. In this manner U.S.G. improves on nature's most valuable resource, wood--by creating Duron Hardboard to serve business and industry in an almost endless variety of ways. BB019 0497 DURON is exceptionally well suited to a variety ot operations, and these are performed by selected fabricators strategically located across the country. DURON can be laminated to other materials with adhesives; or sheets of DURON can be laminated together. It can be machined with hand or automatic shapers; it can be punched, die-cut, perforated, or bent. Just as important as the "smooth-both-sides" feature of DURON is its ability to take a wide variety of finishes, such as paint, enamel, lacquer, wood graining, and plastic. BJ3019 0 4 9 8 left: The suitability of DURON for cabinet making is further emphasized by its wide acceptance in the manufacture of furniture. The picture shows a functional arrangement of cabinets, as often seen in the libraries and classrooms of today's new schools. The sliding doors and cabinet tops, shelves, sides and backs are formed of this smooth, sturdy material. opposite page: Graphically portrayed here are but a few of the ideas developed as manufacturers have learned the multiple advantages of hardboard. B B O I9 0 4 9 9 Scores of different industries are represented by the many users of Duron Hardboard. Among these users are the display and prefinished wall panel industries, furniture manufacturers, and companies whose toys, games, and novelties are distinguished for quality and durability. As designers, engineers, and manufacturers see how others are using this versatile material, ideas will undoubtedly arise that will warrant consideration of Duron Hardboard to improve products and reduce costs. BB019 0500 J.S.G. insulation >oard or ndustry Like hardboard, USG* Industrial Insulation Board is formed into large sheets from wood fibers. In contrast to hardboard, however, it is resilient and light in weight. Yet, it is exceptionally sturdy, tough, shock-resistant-- and low in cost. Another advantage of USG Insulation Board is that no special equipment is required in its fabrication, for it can be sawed, drilled, punched, and shaped by hand or standard machines. The photo above shows the use of USG Industrial Insulation Board in the prefabrication of floor sections for mobile homes. Although its high degree of thermal insulation is the quality for which it is most prized in the design and manufacture of house trailers, its inherent rigidity further increases the structural strength of the trailer framework. Because it has so many practical advantages, possible uses of versatile USG Industrial Insulation Board should be studied carefully. Still unrealized are many of its potentialities in industrial operations and manufacturing processes. BBOl 9 0501 (A) Specially treated Industrial Insulation Board is often used as a filler for expansion joints in highways. (B) As protective packing, Industrial Insulation Board helps prevent damage to heavy objects in transit, such as stone and machinery parts; its light weight means easier handling and lower shipping costs. (C) Its soft but durable composition and good paintability make it an ideal material for games--such as dartboards.
