It’s simple to understand but takes trial and error to get working. You use a “sinker” ink to cause other inks to sink through the resin. The ink I’m using, after a bunch of YouTube recommendations, is piñata blanco blanco.
Fill your mold about 90% to 95% and then add two drops of a color and then 2 drops of the sinker, then do it again so you have layers of color, white, color, white. Let the alcohol sit for a little bit to evaporate and then cover the dyes with any remaining resin. Everything at the surface will kinda mix together but the inks are already sinking below. Let it cure and see what you end up with. Give it extra time to cure before any sanding or polishing because the excess ink will slow the process down.
Don’t use too much white or a lot will sink to the bottom and create a soft spot that won’t fully cure.
Ok. I’ll go look up “petri method”, thanks. 🤓
