My first attempt to press recycled shellac from a stamper I made. 100% recycled material seems to have experienced some sort of oxidation and/or polymerization. Some new material will probably need to be added. Does anyone know where to buy powdered or flaked shellac?
For those who want to know, pressing was done at ~300*F and ~5 tons.

PS. Many of you know about my reproduction discs and the only way to continue the project is if people are willing to loan discs that will make desirable copies. Please contact me if you're willing to help, either now or in the future.

Thank you for your support while I resurrect 78 and diamond disc technologies.

I believe flake shellac can be found from suppliers of furniture restoration products. In the quantities needed to press records, though, it may be very expensive. Also, it depends on what grade of shellac you will be using: it goes from "button lac", all the way up to "white shellac".
