^ ail-glass fiber which has come to aid tbs other
fr4ftV fiKor* \n doing the work of the world. This interest is
understandable when we remember that glass fibers possess
properties and characteristics not found in emnl&r combina
tion in anyother commercially available material. * Weallkiwtheattributes ofglasswinchmakeit one ofthe
most perfect of all man-made materials--Us plasticity when
molten,its hardness and strength, He deanliaese and itsgroat
durability. All of these desirable attributes of glass in solid
form am retained when glass is transmuted into fibrous form.
But maddition, the original properties arc extended by many new properties not found in other organic or inorganic ma
terials of comparable utility. There are two basic fom of Fibcrglas--a wool form and a
textile fiber form. WooWikc fibers arc used primarily for thermal insulation, purposes; coarser fibers of tilts same
