I hate wasting resin. I realize a little leftover isn’t a big deal in the grand scheme of what I have to get done every day, but I hate it nonetheless. There’s just something about throwing away epoxy resin that I worked so hard to measure, mix, and get bubble-free that seems so … well … wrong. Instead, I have a list of resin coloring experiments to try when I’ve got extra mixed resin. I thought it would be fun to show you what happens in the (resin) mad scientist lab.
Step 1: Find random things to use for your resin coloring experiments.
I scoured my house and studio to see what I had handy to mix in the leftover resin. Here’s what I found:
1) red kids’ paint (the label didn’t specify the ingredients, but I’m guessing it is a water-based paint)
2) blue sidewalk chalk
3) paprika (yes — that one — from the spice cabinet)
4) kids’ watercolor paints
Here’s what the resin samples looked like after I stirred each for about a minute.
Step 2: Add to a silicone mold.
I had an imperfect silicone mold to cast my resin into.
💡 Pro tip: When doing resin coloring experiments, you never know how your resin will turn out. Sometimes inclusions and colorants can keep the resin from curing. When deciding whether to pour your experiments into a mold, use one that you can afford to lose. Your resin may turn into a sticky, goopy mess. If you don’t have a ‘throwaway’ mold, let your resin cure in your resin mixing cups.
Step 3: Demold and assess the results of your resin coloring experiments.
Here are how the finished samples turned out. The red paint colored the resin well. I’m surprised the resin cured without any problems. Water-based paints have extra moisture that can cause resin curing problems. The chalk and paprika colored the resin more effectively than I thought they would. In fact, I wasn’t expecting the pastel chalk to color so darkly. The watercolor paint shavings managed to tint the resin some but couldn’t dissolve in the resin.
The effects are more pronounced when you hold them up to the light. You can see particles in all the ones where I used powder pigments.
