Week 3 Lab: Group B Pottery Data

Clay Forming

My group — consisting of Margaret, Max, and myself — had to create a clay body that was 500g clay and 100g temper. The temper was made up of 80g of sand, 18g of gravel, and 2g of chaff. The chaff came in two varieties: small wood chippings and long strands of straw. Each member of the group used a different composition of the two chaffs. Margaret used exclusively wood chippings, I used exclusively straw, and Max used a combination of both. When we started working the clay, it was difficult to see how the clay body would incorporate the temper. However, after a while, the temper was properly incorporated, and we could get to work on our pinch pots.

Here are the proportions of clay and individual tempers in our final clay bodies:
