A bstract The operation in enameling that is the most difficult to control is the setting up of enamels for dipping. The difficulty occurs because there has been no practical accurate method for measuring the set of the enamel. Practical experience shows that viscosity is not an indication of the set or of the dipping weight. The method presented consists in determining the apparent specific gravity of the enamel slip with true value for the specific gravity. Calculations give a numerical value for the value of the set or yield point. The measurements are accurately reproducible, and dipping weights have been found to correlate quite well with the results given of tests in laboratory and plants.
