I found the pattern and structure of the shattered pieces to be fascinating enough that I made a cab out of one.
Many years ago, I did some heat treating of agates to enhance the color; but it has been so long ago that I forgot the recipe. Knowing that I would probably try it again sometime in the future I had been saving various recipes, most of which were for enhancing the characteristics of flint for use in knapping.
