Field observations of lubricant type and level control are presented with the intent of promoting laboratory routes to developing better rigid formulations. Calcium stearate is identified as a gelation promoter. PE wax is described as a very effective gelation retarder. POPE is an effective slip agent, ineffective retarder, and slight promoter. It is obvious that more understanding of the functions of lubricants is needed to permit on‐line formulation adjustment.
