Sometimes, when I am sorting through my slabs and trim saw cutoffs, I come across a particular piece that I know I want to make something with, but at that time I can’t picture exactly what.

HOW TO PUT A PROTECTIVE CAP ON A CAB
To protect a specimen cab, often a cap is needed. In my case, I had a slab with the because of the color of the background and the pattern. This background had a more silicified consistency than most sandstones. It had no graininess like most sandstone, so I'm inclined to compare it to a jasper. The pattern was typical of a dendrite.
