It’s around 8 inches. Those kind of pieces are the sorts of things you have to see in person to really appreciate.
While that piece doesn’t really do much with it, since a lot of his work is exploring printing on glass, Lepisto uses layering, varying translucence and bubbles and things as part of the medium. I like layered printing on glass esp., there’s a lot of interesting things you can do there, though it’s hard when you’re dealing with printing on a thing that’s a fluid at some points during the process.
