Re: gum preservatves (polyester resin)



But I'll look for the polyester resin -- whatever that is. It reminds me that I came across a formula for "resinotype" in an American Annual of Photography from the 1920s... Very frustrating: It calls for "resin" but doesn't say what kind.
Simply change a vowel: rosin
