Columbus Clay Co. #4150 Red

Note: Shiny Transparent Pink. I use this next to the Rivulet Pink.

This would be an excellent base for other colors.

Zinc Oxide

Copper Carb.

Note: A beautiful glossy transparent glaze. I use this next to the Rivulet Green. Because of the zinc, this glaze would be an excellent base for blues and greens (cobalt and copper) but not for all colors.

Manganese Diox.

Note: This is another shiny transparent base.  I use this with the Rivulet Blue. This, like the Pinnell Base, would be a good glaze to test with other colorants. Both are smooth and stable without much variation.
