<p>[QUOTE=&quot;calcol, post: 2775284, member: 77639&quot;]I not only have heard of it, but still have a supply.&nbsp; After I use a bit, it goes in the recycle bottle.&nbsp; When the recycle bottle is full, I distill it.&nbsp; It was a high temperature refrigerant, called Freon-113 or CFC-113.&nbsp; It was used extensively as an industrial solvent too.&nbsp; Colorless; nonflammable; liquid at room temperature, but volatile, so it would evaporate quickly; nontoxic; would dissolve lots of oils and greases, so ideal for degreasing coins.&nbsp; Superior to acetone because there was no chance of fire or explosion.&nbsp; It was more inert than acetone in that there were fewer things with which it would react chemically.&nbsp; However, it&#039;s one of the best ozone depleters, so getting new stuff is almost impossible.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
