My third bowl made from cholla and epoxy. I laid the cholla canes in flat, rather than standing on end, and poured multiple colors of epoxy, tilting the blank a different direction with each pour. The bowl is just over 9 inches in diameter, and just under 2 inches high (so it probably is more of a plate than a bowl).

My second bowl made from cholla wood and epoxy, with blue, green, yellow and red tints in the epoxy. The blue is darker than I intended, almost a black, but I think overall it works.
