§ 24. Mr. Leslie
asked the Parliamentary Secretary to the Ministry of Works whether he has any knowledge of the process employed by the Scottish Oils, Limited, whereby the refuse of shale bings mixed with 10 per cent. of lime makes excellent bricks?
§ The Parliamentary Secretary to the Ministry of Works (Mr. Hicks)
Yes, Sir. Full information of the process is available in my Department. Sand lime bricks made by this process are at present being used on building work in Scotland.
§ Mr. Leslie
Is my hon. Friend satisfied as to the durability of these bricks, because so many other bricks in the last 20 years, when just touched by frost, have simply crumbled away?
