I’m back today with more resin petries (my best yet!), as well as a video showing how to make them. These resin petries are fun and easy to make, and while I hate having to wait hours and hours for them to dry, taking them out of the molds is like unwrapping a present. You never know what you’re going to find.
Here’s the video tutorial…
(Having trouble viewing that? You can click here to watch on YouTube.)
I just love these little resin petries. They’re an explosion of color and pattern and depth and texture and interest. They’re basically all of the things I like encapsulated in one four-inch disc of resin.
You can use them as coasters, or frame them (stay tuned for a tutorial on that very soon), or just prop them on a little easel so you can enjoy seeing the colors and amazing depth and designs trapped the resin. They really do resemble something you might see growing in a Petri dish. 😀
To make these, you’ll need to gather up a few supplies:
First, you’ll need something to mix your resin in. I just stock up on these little 2-cup plastic measuring cups that I get at my local neighborhood grocery store.
Then you’ll need something to mix the resin with. I buy these little spatulas in bundles of four at my local grocery store. When working with small batches of resin, I prefer to use a small spatula so I can be sure that I’m getting every little drop of resin mixed thoroughly.
And then you’ll need a measuring cup. Each four-inch resin petri takes 1/2 cup of mixed resin, which means you’ll mix 1/4 cup of resin and 1/4 cup of hardener. I just use cheap plastic mixing cups.
As for the actual resin, I use ArtResin, which you can buy on Amazon or directly from the company. I like this brand because it was developed by artists for artists. It dries crystal clear, doesn’t yellow like other resins do, and it’s non-toxic with no VOCs, so you can use it without a respirator. It comes in two parts that have to be mixed together. One part is labeled “resin”…
…and the other is labeled “hardener.”
And it really is as simple as mixing equal parts of resin and hardener (again, for these petries, I use 1/4 cup of each) thoroughly for at least three minutes, then you’re ready to pour.
And let me give you a quick tip. Don’t mix up the lids. Don’t put the hardener lid on the resin, and the resin lid on the hardener. Yeah…ask me how I learned that. I thought I’d never get those lids off the next time I tried to open them! 😀
So what do you pour the resin into? Well, you’ll need some silicone molds. These are the ones I have, but as you can see below, I cut them apart to make each one easier to handle.
And you’ll also need some alcohol inks. This is the set I have, which I used in the video, but I also just ordered this much larger set, which should arrive this week. I’m excited to play around with a much larger set of colors.
Any time I use resin, I also use this propane torch, which I picked up at Home Depot.
It gets the bubbles out when you pour thin layers of resin (the recommended thickness of each individual pour is 1/8 inch). But when pouring thicker layers, like on these petries, it’ll get most of the bubbles out but you’ll still have some. I still recommend using either a propane or butane torch, but it’s optional. Just know that if you don’t, you will have bubbles. But that might make these petries look even more interesting!
Before mixing the resin, you’ll also want to put on gloves. The resin is very sticky, and it’s difficult to get off of your skin. So I just pick up a box of disposable gloves at Home Depot to use for my resin/staining/polyurethaning projects.
So with all of your supplies in hand, all you do is mix equal parts of resin and hardener (thoroughly for at least three minutes), then pour the mixed resin into the silicone mold. Use the torch to get the bubbles out, and then you’re ready to drop the alcohol inks onto the resin.
There’s no right or wrong way to add the ink. I just add drops of ink in random patterns, and I like to add white ink after each color to make the colors show up more. You’ll notice that the colors on their own seem to have a transparency to them, but adding the white after each color seems to make it a little more opaque and vivid.
Once you’ve added the inks, you can see the inks start to move and mix on their own. You can use something like a straight pin to swirl them, but it’s not really necessary. The inks move just fine on their own.
After about 10-12 hours (or maybe longer, depending on the weather and temperature), you can take them out of the molds and see what designs the inks created in the resin.
Here are a few detail shots of the three resin petries from the video. These are the best results I’ve gotten so far. There’s just so much detail and depth in these!
Aren’t those amazing? I could seriously stare at them and study the detail for a very long time.
I’ve been trying to find the best way to use or display them. I personally don’t like the idea of using them as coasters since they aren’t the least bit absorbent, and I only drink iced tea. The condensation on the cup would just pool onto, and eventually run off of, the resin disc. But I do like the idea of framing them. I’m working on that right now, and I’ll show you the results soon. I think it’ll look pretty amazing!
