This listing is for 3.4 ounces of pulverized shale from Felkins creek in Madison county, Arkansas. All of my rocks are sustainably wildcrafted by taking what is available on the surface. We do not mine for rocks. If you’ve ever been to our part of Arkansas, you’ll see that rocks are an abundant resource here!
You’ll need to grind it finer to make paint, but the starting point is a lot less time consuming than if beginning from whole rocks.
Some pigments need to be washed before you use them. Shale is one. If you don’t wash the shale, the resulting paint will stink like rotten eggs until it is dry. The source of the odor is sulfur compounds, and is water soluble so washes out easily. Do the washing after you’ve crushed the pigment to your desired mesh. You can read more about how I make my watercolor paint from this pigment at my Color Journal.
Watch this listing for more offerings soon! I have a new mechanical rock crusher and once it’s operational, I’ll be able to offer a wide selection of pulverized Ozark pigments in addition to the whole pigment rocks already on offer.
