* a mixing stick
* a pair of disposable gloves
* 4 art stands to display your cute pieces!

If however you're fully addicted to this fun art trend, then you'll want to buy in bulk!
We sell ArtResin, alcohol ink (8 colors), silicone molds, and accessories a la carte as well.



💡TIP: Did you know that Ink Sinker is the secret behind making perfect petri dish coasters? It's true! Ink Sinker is a white alcohol ink that has a different density than the other colors, and it has the unique ability to push alcohol ink colors down through the resin, creating tendrils and other cool effects!

Before You Start: 

- Warm up your resin and hardener bottles in a warm water bath prior to mixing. This will help any bubbles escape later in the process.
- Working in a well ventilated area and wearing gloves, measure your ArtResin resin and hardener in precisely equal amounts by volume.
- Mix thoroughly for at least 3 minutes, scraping the bottoms and sides of your mixing vessel as you go.
- Fill each section of your mold halfway with ArtResin.

⚠️ PLEASE NOTE: We don't recommend using a torch with this project! By warming your resin and hardener in a warm water bath prior to measuring and mixing, this is the best way to reduce bubbles.

And now, you're ready for the fun part!! 

Step 1) 

  • Add 5-10 drops of Ink Sinker into the ArtResin

Step 2:

  • Add 5-10 drops of pink or red alcohol ink on top of the white

Step 3:

  • Scatter 10-20 drops of gold alcohol ink onto the pink/white drops you put down in Steps 1 and 2, and onto the rest of the resin surface

Step 4: 

  • Place 10-15 drops of pink OR 5 drops of white, followed by pink or red

After your resin petri dish has cured for 24 hr, peel the silicone mold away from your resin petri dish ...
