Hello, made a reddit account just to ask this. I have a dnd group with friends and wanted to help make some potion props for our meetings, and Ive seen a couple different things for the base like hair gel, water, etc. I just wanted to know if someone knew what this was? It looks slightly thicker than water, but not gel i dont think. It seems they add mica maybe in the mix. I thought it was resin but I think all resin hardens. Im just not sure what this is and this was the kind of texture my dm wants. Thank you.
