 Can I use Art Resin to make coasters and hot plates? Yes, Art Resin works great for coasters, not so great for hot plates. And here's why. The maximum temperature that cured Art Resin should be exposed to is about 120 degrees Fahrenheit. Any temperature higher than that may lead to some irreparable damage on your surface. The heat from a hot mug, on the other hand, is nowhere near that hot, so you can put it on a coaster without worry. You can make coasters out of wood, tile, glass mosaic. You can pour it in a silicone mold. You can embed objects in there if you wish. There's all kinds of creative options. Just have fun.
