In terms of a given apparatus of suitable standard dimensions the plastic flow characteristics of various ceramic slips may be measured and recorded. Each slip has its characteristic plasticity which is a highly important factor in connection with its successful use in the specific process for which it is intended and this plasticity may be adjusted at will in order to obtain the most desirable working condition. The types of flow which have been arrived at through long experience and employed in the art even without a means of measurement arc shown for various commercial enamels, glazes, and body slips. A useful deflocculation test for the classification of clays and the testing of their uniformity from time to time is specified. This description covers a means for control or regulation of the slip whereby (1) uniformity may be obtained in the application of white or colored enamels and glazes, (2) crawling and “settling out” difficulties may be avoided, (3) uniformity of consistency for spray operation from week to week may be checked, (4) accuracy of batch mixing may be checked, (5) casting slip control may be effected, and (6) in general, any other property such as case of filter‐pressing or sieving which depends wholly or partially on a proper slip consistency may be held at the most desirable value.
