HC Deb 16 July 1942 vol 381 cc1348-9
37. Mr. Hannah

asked the President of the Board of Trade whether he can give the House any information about the possibility of using heat-resisting glass as a substitute for rubber in the manufacture of hot water bottles?

The Parliamentary Secretary to the Board of Trade (Captain Waterhouse)

Consideration is being given to the possibility of increasing the output of substitutes for rubber hot water bottles, including those made of heat resisting glass, having regard to the competing demands for labour and materials for war production.
