Shellac does not dissolve in alchohol I have quite a lot of shellac flakes in plastic self seal bags ,airtight I assumed.
When I add to methylated spirits it will not dissolve .
It is anything up to 5 years old and has been kept in a region where humidity is generally above 80% all day and night .
I tried adding proper auto paint thinners to the mix but this did not seem to work.
So I microwaved some to try and drive out any moisture the flakes may have absorbed . The flakes heated up some and partially melted but this had no effect and it still will not dissolve.
Next I will try in the direct sunlight or a bowl in a low oven.
Does anyone know what might be happening chemically here?
I want to save and use the shellac if I can. |
