If you haven’t heard about Bio-Solvents you need to. I just finished the “Orange Power” PDR newsletter which discusses these green but powerful solvents. Some brand new chemistry here. Also mentioned are a couple of different compositional abrasives, microcrystalline super-abrasives, and zirconium oxide to blend with such solvents for the purpose of working on defective tempered and annealed glass. All together eight different ingredients for your chemical tool box. This newsletter turned out to be much more than even I expected. Do I have your interest?
