I hate wasting resin. I realize a little bit 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 resin that I worked so hard to measure, mix, and get bubble-free that seems so … well … wrong. I always have a list of resin coloring experiments and ideas of things to do the next time this happens, so 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
After dividing the resin into 4 separate 1-ounce mixing cups. 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 exactly what it was, 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
The picture here gives you an idea of how much I added to each small cup of resin.
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 and decided to pour some into each of the 1-inch squares.
An important note here: When doing these experiments, you never know how your resin is going to turn out. Sometimes inclusions and colorants can keep the resin from curing. When deciding whether or not to pour your experiments into a mold, use one that you can afford to lose if your resin turns out to be a goopy mess. If you don’t have a ‘throwaway’ mold to use, then let your resin cure in your 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 as I expected it would. I am also surprised that resin cured without any problems, even though 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 as well. In fact, I wasn’t expecting the pastel chalk to color so darkly. The watercolor paint shavings managed to tint the resin some but weren’t able to dissolve in the resin.
The effects are more pronounced when you hold them up to the light. In all the ones where I used powder pigments, you can see particles.
So what do you think? What resin coloring experiments have you done?
And if you hate wasting resin too, here are some other leftover resin project ideas.
