Cutting and lubricating composition for use with a wire cutting apparatus

A polar organic solvent based lubricating suspension carrier composition for use in cutting or slicing workpieces of a hard and brittle material with a wire saw, or other cutting or grinding tools prepared by admixing:

• a) from about 0 to 10.0 weight percent of a non-ionic surfactant;
• b) from about 80 to 99 weight percent of a polyethylene glycol or glycol having repeating units of 2-5 carbon atoms or the co-glycols thereof;
• c) about 0.3 to 6 weight percent of an organic polyelectrolyte partially neutralized in situ to form gelatinous or gel micro-particles with a density slightly higher than that of the surrounding medium, and
• d) water.
