re: Exothermic epoxy

It did, Nathan. The after picture is after I turned off the plastic cup (which hadn’t melted, but had seen some heat) to see what was inside. The surface of it next to the cup was relatively good-looking, but I could feel that it was lighter than it should’ve been. I’d guesstimate I lost 20-25% of the total mass of epoxy.

I was trying to blend the colors, so doing this as separate pours (maybe four for the cup?) will be tricky. Ideally, I’ll let the first pour get past peak heat and start cooling, then mix and pour the next layer before the first has fully cured, so I get a little mixing between the layers… or maybe I’ll change my design and tilt the cup so that the layers blend less, but run at angles… dunno. Mañana.
