A while ago, on another site cough cough I posted some initial attempts I made at some petri dish art. This is done by pouring resin in plain petri dishes, and then dropping in various colors of alcohol ink. It’s really a fascinating process, but the end results are quite unpredictable. I finally got around to making some more and I really think I’m starting to get the hang of it!
Thank you! A friend I have gifted some of my earlier works is using them exactly for that. It’s definitely possible. I think I’d want to back the bottom with some felt though. It’s not flush against the bottom, so I’ve experienced some cracking on the rim when trying to use it as a coaster (my wet glass would stick to it, and pick it up and the drop it…yeah, I’ve learned…lol)
No, plastic. I didn’t know glass petri dishes were a thing. Would up the quality on the end product I’d say. Not that I think the plastic petri dishes come off looking cheap - you barely notice it really.
Not too hard at all - the major thing to be mindful of is how big your petri dish is vs how much alcohol ink you put in it. Based on all the results I’ve had, too much alcohol ink will drop to the bottom and make it look like my beginning examples (sort of like brain slices, cool but not what I was going for), and not enough ink will not get the drippy growing effect. It’s tricky to gauge which is why I still think the results are kind of a crapshoot til you get the feel for it.
