This was the intended outcome. I got some new inks and thought one looked like coffee and I was pretty sure that the petri method would look like cream in it.
Itās simple to understand but takes trial and error to get working. You use a āsinkerā ink to cause other inks to sink through the resin. The ink Iām using, after a bunch of YouTube recommendations, is piƱata 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.
Donāt use too much white or a lot will sink to the bottom and create a soft spot that wonāt fully cure.
Iām using piƱata blanco blanco. I didnāt really believe it but all the other whites (3 to be specific) I tried did not work as well. I did 2 drops of ink, then 2 drops of piƱata and I did that twice for each die.
Most of my previous experiments were just with extra resin in a dump mold so I didnāt really count them. I had one that looked promising but when I tried it in dice it didnāt work well at all, just kinda sat near the surface and only slightly penetrated downward.

I'm super curious about both the intended outcome and this one pictured. š¤©š¤š¼

looks almost like the underside of a mushroom

Thatās why itās called petri, looks like some kind of fungus growing in a Petri dish.

Ah I wasn't totally sure I knew how to spell petri so I wasn't sure if it was refuring to a petridish

I can't ever get white alcohol ink to do me justice. What am I missing?
