The point you make about Nr Jolley in Para4 is a rory sorlous on# and Nr Nana will bo having a word with Nr Yilaoa about this to see that the prospoets for glass eloth on land basod Insulation aro nothing llko as big as wo previously thought I an afraid wo did not got a cross chock on this point yesterday at Darlington Insulation but Nr Nann has arranged for Nr Wilkinson to follow up this point With respect to the point in Hr. Harper's nano of tho 10th January about ICZ placing a contract with Darlington for an asbestos-free nagnssla insulation, I can certainly confirm that this Is so It is d e a r fron what Hr Grant said that Darlington have done a lot of work on finding substitutes for asbestos and not just in combinations with magnesia but with other Materials as well We raised the question of glass and they are at present evaluating a sample of "A" glass that Hr Wilki has recently arranged for then to have Z was surprised hen they said that "X* glass was no good because it was attacked by the insulating material Z poited out to Mr Laldler (Works Director who was -- king this point) that aagnesla was alkali and not ~?id and then he said he was not talking about magnesia but another material, unnamed, that was not very important! in short, Z could not set a straight story from them about their work with glass and when we get a report on their position with glass it might be useful for someone from Glass "search y Department to go and see them D.tf.
