Gamblin Magnesium Carbonate
Magnesium Carbonate is traditionally used to stiffen ink. It will also reduce an ink's gloss level. Once added to ink, Magnesium Carbonate becomes transparent and will not alter the color of the ink. We recommend adding small amounts at a time; little is needed to add body to an ink. Mix well. It can be used with both etching and relief inks. Available in 16 oz.
