Make some Test samples and try and break them! A suggest practice for warming epoxy is set your bottle in a pan of hot water. I have heated mixed resin and hardener in the microwave before. That makes the mixture more runny/less viscous for a few minutes but makes it set up faster kinda like turning slow cute into fast cure. I’m not sure what putting just resin or just the hardener in a microwave does to it if anything but I know warming it in a pan of warm/hot water is safe.
