Fluxing agents used in most steatite bodies contain alkalis which lower the electrical resistivity of these insulators. Attempts were made to obtain a vitreous steatite composition by additions of oxides containing no alkalis. The effect of grain size, liquids, and varying pressures was determined to obtain the best mixture which would produce the lowest absorption when fired to cone 14, and to this mixture the various oxides were added. The absorption and shrinkages were obtained after firing to cones 13 and 14.
