I believe ETI's  pamphlets say the only way to get it off once it's dried/set is to sand it or use a heat gun, but I don't know if heat would make glass crack or not.

if you can't lie no better than that......you might as well tell the truth.

I'm a heavy user of Goo Gone, but I haven't tried it on dried resin yet.

hey! it's my first post here. i've read this thread a few times before actually starting to work with resin (at least the first 50 pages) and it's answered a lot of my questions, but i ran into a problem.

i used castin craft in an ice cube tray (with mold release). i'm reasonably sure that a combo of messed up mixing proportions and humidity caused a stickiness issue, but it's the top (the part that was actually in the mold) that was sticky and not the part that was exposed to air.   Huh

i used one as a tester and tried to wet sand the sticky part off (in water), but it didn't do much besides make the surface cloudy. was there some kind of chemical i was supposed to wet sand it in?? should i just keep sanding and try to polish it afterwards? or should i have tried to spray a layer of sealer over it and then sand it?

What kind of ice cube tray?   Did you have a thick pour?

table glass is generally VERY hard, a hairdrier isn't going to hurt it. don't heat and then cool or cool and then heat Any kind of glass quickly though because that Will crack it for sure! glass is also more suseptible to cracking when it's cold and gets hit with something.

in other words, i'd try the hairdrier method. let us know if it works!

it was just a plain plastic dollar store ice tray. i'm not sure if it would be considered a thick pour, but it was about 1/2" thick and each one had an embedment in the middle. it took like 2 weeks to cure and i didn't use any dies.

This sounds like a mixing problem-- not enough catalyst. If you didnt mix pigments or anything I would guess that proportions were wrong. Which means, the only way to cure the outside would be to spray it with something-- an acrylic spray, like a polyurethane sealer, or castin craft' resin spray, which is the same thing, basically.  This will make the outside not sticky in most cases, but it sounds like your pieces didnt cure throughout, so I dont know if that will lead to problems in just trying to seal the outside. If they hadn't cured in 2 weeks, they won't ever cure, I don't think. Try sealing them, though, it just might work.  Are you using poly or epoxy resin?

I called a company that uses resin for construction purposes when I got resin all over my roommate's laminate top table. They said they did not know of any chemical agent that would dissolve resin, and in the end they suggested using a razor blade (I used the one that is a flat blade that comes out of a handle, used by my father to scrape paint of windows and windowsills, I dont know if it has a proper name or formal use) and it worked by "breaking the seal" on the resin on the table, popping it off that way. It involved trying to pry up an edge of the resin, but using a razor on glass might scratch it.  But it worked because it was a really thin razor attached to a handle. I just kept scraping into the edge of the resin till it popped up.  I don't think any solvents or heat will work on it.....

it's polyurethane resin. i read somewhere that polyurethane resin cures in absence of air so i put the pieces under a tupperware bowl for about a week and took a look at it today and the pieces are a lot less sticky than they were when i first wrestled them out of the mold. i think you're right. i didn't use enough catalyst. i got some deco art triple thick gloss glaze, but that won't seal it, right? should i spray with acrylic sealer and then the gloss glaze?
