I stumbled across this great book at the Internet Archive. It's aim is to provide craft skills in school and solve the problem of pottery and tile making without a kiln. Portland Cement is the medium but the skills are the same as potters. The tile making is very interesting and easy to do at home. Also of interest are slip techniques in cement. Published in 1922.
