§ 64. Dr. Stross
asked the Minister of Education why he proposes, in his memorandum to local education authorities, dated 9th November, 1955, that raw lead glazes may still be used in advanced courses in ceramic design and technology; and whether he will give an assurance that such lead compounds will be used only rarely and for the purposes of fundamental research.87W
65. Mrs. Slater
asked the Minister of Education on what grounds he suggests in the Memorandum 517, 9th November, 1955, that the use of raw lead glazes in advanced courses in ceramic design should be permitted when the use of these glazes has been forbidden in the pottery industry for some years.
§ Mr. Vosper
Raw lead glazes may occasionally be needed to demonstrate the development of pottery making and the results produced by different types of glaze. The advice my right hon. Friend has given is that their use should be very rare and limited to advanced courses in institutions of further education. He is sure that the responsible authorities will exercise due care.
