Resin is AFAIK a generic term -- I think even gum arabic is "resin" tho
possibly at the time that meant 'Canada balsam,' which I now forget the
composition of. I'd beware, though, of something that's mostly turpentine,
I'm told one of the two most allergenic substances to humans (the other
being chrome, as in dichromate). However being ever interested in "resin"
as I seek a varnish for gum, I checked DS catalog for resin -- not listed
in index. Any recollection of what/where?
It does seem, meanwhile, that this "transparentizer" is largely wax. The
melting with heat works very well without the volatile solvent, at least
IME. However, and here's a wild guess, sticking my neck out -- reason for
the "resin" may be that beeswax is on the soft side. We've had very good
results with parrafin and hot iron. The parrafin is hard when cold.
