Varnishing, shellacing, or polycoating sugar cookies Answered

What would be the best paint-on preservative (some type of clear coat; varnish, polyurethane, shellac, etc) and the method to use to seal a frosted sugar cookie so that it would be durable, colorfast, and not get moldy or crack? I'm not looking to seal it into a block of acrylic, I want to keep it looking like the original cookie.

Yours unpreservedly,

How about epoxy resin? See Peter Brown's videos on Youtube, he put food in epoxy and AFAIK it still looks good somehow...

1. Unless it is very dry or sterile it will still decay inside your coating.
2. It won't look normal once coated.
3. Dip in your selected medium, resin is a good durable choice, varnish might work OK.
If you want an effect like the japanese plates of plastic food get creative with Sculpty (Fimo)

Right on, thanks for the practical advice! We decided to get some "test cookies" from the store before going after our art piece, and they are hopefully now drying out in separate containers with all the silica gel I've saved for no particular reason. Since it's - 4 F outside, they should be as dry as the skin on my hands in no time at all.
We're planning on trying something different on each lucky test subject.

If anyone has done this before, I'd be happy to hear how it went -

Clear shellac would work without giving it the amber tint you'd get using oil based poly. For that matter, a waterborne poly would probably work too. In either case, don't try to get too much on the first time or you'll probably smear any colors.

I like shellac because it dries quickly and it's easy to apply, as long as you don't try to smooth it on, which can be disastrous, since the new coat will start dissolving into the previous coat(s) and you'll both get drag and the possibility of smearing your fine work.
