Excerpt from Notes on Clay Deposits Near McMurray, Alberta
The overburden along this stream will, in most instances. Be very heavy.
Laboratory No. 302. This is a grey, highly plastic, fine grained clay, requiring 28 per cent of water for tempering. It has good working qualities. The drying shrinkage IS 8 per cent. It must be dried slowly to avoid cracking.
On burning to cone 010, a dense, steel-hard body is produced, having an absorption of 10 per cent, and fire shrinkage of 1-3 per cent. If burned to cone 06 the absorption is reduced to 4_per cent, but the fire shrinkage 15 too high, being 46 per cent.
Burning to higher temperatures produces bloating, unless the firing is done very slowly. 'the clay is intact at com 3, and will probably stand a much higher temperature but the presence of carbonaceous matter is a defect, and interferes with the development of a good product.
Laboratory No. 303. This clay is light grey in colour, and rather calcareous. It requires 27 per cent of water for tempering; the working qualities are good; the wet body is fairly smooth and free from coarse grit. The clay can be dried as fast as desired after moulding, the drying. Shrinkage being 508 per cent. The following results were obtained on burning.
