I am doing some simple molds with dried flowers inside the silicone and rubber shapes. I used the 2 part Amazing Clear Cast.. Some completely cured, others are still tacky, weeks after. I am supposed to give these at a celebration of life ceremony next weekend and need a fix! Can I put them in the oven? I've even tried a second coating, same result. HELP please!

If you put them in the oven BE CAREFUL, it can be done but you need to make sure to keep the temperature low and be sure to air out the oven for a few hours after (if it's your kitchen oven). I wouldn't go over 275 degrees (same as for baking clay) as the resin will "soften" at a high temperature and you don't want that. If you have an oven you use specifically for baking clay then that would work best, just be sure the temperature stays on the low side and do it for no more than 15 minuets at a time. Let it cool in between or there might be a chance of actually discoloring the resin - Brian's done a test of whether or not resin will burn but I don't think it was with one of the Clears so I can't remember if a Clear would get discolored or not when exposed to too much high heat.
A little heat is what is needed to cure resin but you also don't want to go too high and have it go soft instead of curing. If you have a heat lamp, you can put them under that - just not too close. I have a 3D printer and have been known to have it do double duty when I'm printing by putting slow curing resin castings or any mold I want to speed up the cure on into the case I keep my printer in - the case holds the heat nicely and I have air purifiers in place for the fumes so it works for me. A high heat is what is needed to "fix" a bent or warped resin casting so that is what you DON'T want to use as you're only needing to accelerate the curing.
