So I am working on my own custom acrylic cast eyes and have run into something strange...
I always let my resin cure under 60psi pressure in a pot (my silicone molds too). I used mod podge to brush on the thread veining (using embroidery thread). I did thin the glue with a bit of water before brushing. I used a printed out paper iris and glued it in place with mod podge. I let it dry an hour before pouring the final outer coat of clear resin in the mold and left in the sealed pot for 24 hours.
I opened it up today and I can see tiny bubbles within the clear resin. I am using Smooth On brand EpoxAcast 690. What have I done wrong? Did I use the wrong glue maybe?
It is difficult to see since I haven't polished it yet but here is a picture...
