You can put everything I know about novaculite into a thimble and not have to worry about any spilling over the sides. I do know that a lot of novaculite is quarried, so be prepared to dig. Take along a prybar, a shovel or two, a rock hammer or copper billet to test rock with, and some buckets to tote that stuff in. Don't forget a strong back either. Novaculite needs to be heated before it knaps well. Once it is heated right, it is like butter. The color varies from pure white, grey, to black, to brown, pink & purple.
That right there is all I know.
Post some pictures of whatever you find. Good luck.
