I thought the colors for pink and blue were decided by the marketers. The
pink matches the panther and the pink Owens-Corning fiberglass insulation.
The blue stuff that I've been using for insulation around the house comes
in both 1" and 2" from the local hardware box store and is Dow brand.
Is the green stuff used by the florists any better or worse that the
insulation? It seems to be a little less rigid/brittle.

There is a recipe for a ceramic coating for foam parts somewhere in the
archives. It uses a certain kind of clay (can't remember which kind off
hand), water, elmer's glue, and dish soap. If you can't find it, I will dig
around for the recipe on my computer. Back when I was doing some casting
(now in an apartment), I used this and it worked great. The coating would
be a very thin black layer on the aluminum part when I pulled it out of the
sand, and it would flake off (usually I could just tap the part on the
ground and most would fall off). I can take a picture of one of the parts I
cast if anyone is interested in the surface finish, etc.
I used both white bead and blue score-board foam. The blue was much easier
to cut and get a good finish with. I was doing all this in loose sand box
sand vibrated to compact it around a part, but my 'vibrating' was just
shaking the flask.
