Nope, I just use my heat gun or a small torch for any air bubbles, and I make my own "alcohol inks" by using mica in ISP alcohol, and they work the same (even though I know they are not the same thing) .You haven't felt the desire for a vacuum chamber or pressure pot? Alcohol inks? I'm sure I'll get up to resin before too much longer. There are so many project opportunities!
That is EXACTLY what it is. We just got back from Yellowstone on Wednesday and my son and his girlfriend said that was their favorite thing to see there. I made it for them. I used the magnet they bought me to model it off of.Beautiful! The second one looks like the Grand Prismic Spring in Yellowstone.
