"It has been observed that one of the weak points in the present method of commercially preparing stiff mud bodies is the de-airing process, which involves passing them thru a vacuum chamber. Difficulties in maintaining a good vacuum, power costs, and work stoppages due to clogged vacuum chambers, are some of the problems. It was thought that perhaps a very definite contribution could be made in the field of ceramic engineering if some method could be devised for preparing a workable ceramic body of good dry and fired properties without the use of a vacuum chamber. In attacking the problem, it was remembered that the ancient Chinese achieve the desired properties in their clay bodies through aging. It is now generally agreed that the advantages gained by aging a clay-water mass are due to the more complete distribution of the water, which is accomplished as a result of the long time interval involved. The problem is to find a way to eliminate both aging and de-airing, by adding compounds or mixtures which are better wetting agents than water, due to their lower surface tension"--Introduction, page 1.
