Grease generally consists of a soap emulsified with mineral or vegetable oil. A common feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease.

How do you make calcium grease?

A lime-oil slurry is prepared by charging 15 parts of a mineral lubricating oil having a viscosity of about 600 SUS at F. and 9.777 parts of hydrated lime [Ca(OH) into an open saponification kettle at about 70-80 F. The oil and lime mixture is stirred without the application of heat until a smooth mixture is obtained.
