What Are ‘Petri Dish’ Dice?

‘Petri dish’ dice feature sinking ink in the resin and is achieved by using a sinker medium. If the sinker is not used, you will get a smokey effect as the ink disperses in the resin. It is named ‘petri dish’ because of the mold appearance that occurs on the bottom of the die face; it’s almost like mold growing on a petri dish used in biology labs.

It is generally considered a more difficult effect to achieve in resin art, unless you know exactly the right combo of ingredients and directions. It took me six months, even with watching tutorials, to crack the code for myself. I’m still trying to fine tune it, but it was worth it to achieve these beautiful results.
