Look closely at the colored vanes of this marble and you'll notice that the white lines are actually fused BETWEEN the two layers of color. How sweet is THAT!! And then there is dichro running through the other vanes between those colored vanes, with the solo white line. Incredible beautiful in hand! I'm telling you, the Hot House guys are doing some things that NOBODY else is doing, and it is COOL. This is one of my very favorite styles from them. Signed with Hot House symbol and 2015.
