Picture 027

This is another "surprise" marble. On the table top it looks almost black. But get some light behind it and you can see that it is actually a spiral of cyan and purple. Again, the colours are too dark to be really effective in a piece this thick -- the density builds up incredibly fast with thickness. It is more successful than the others, though, despite the big bubbles where I didn't get the air squeezed out of the rod bundle quite right.
