I have discovered how to efforlessly remove the "cutting text" off of conservation glass. I am probably not the first to discover it, but I've not seen it mentioned here and I can't explain how happy I was to find this! Simply use a Prismacolor colorless blender marker! It's instant and takes no effort. Over time the ink will build up on the marker tip, but it still works. just clean off any residue with your normal glass cleaner.
