Bentonite Brown 30ml sizer

  • Bentonite Brown pigment is hand foraged in Central Oregon along the John Day River. This clay was formed from a series of volcanic eruptions 35 million years ago depositing layers of ash. This volcanic ash gradually weathered into soils. The soil is a dark brown, silky bentonite clay. In the wild it dries into popcorn like clusters. These clusters are hand ground and levigated to select for the finest pigment particles. This ink is very lightfast. 


    The ink is packaged in 30ml (1 oz.) clear glass bottles capped with a glass dropper lid. The pigment is hand mulled on a glass slab with watercolor medium for a smooth consistency. The pigment in the ink naturally settles over time. Shake before use. 


    The ink is suitable for use with brushes. It can also be dropped directly onto paper and then diluted with water or combined with other water-based paints and inks. The ink can also be dropped into a palette and used as a wet watercolor paint. If the ink dries in the palette it can be rewet for use in the same manner as a dry watercolor paint. Please watch my ink video tutorials for more information about how your inks will arrive, how to use oxgall to counteract floccing, and how to blend the inks. 


    The ink is all natural, but not suitable for consumption. Keep away from pets and unsupervised children.
