Magnesium Carbonate can be added to either an etching or relief ink in order to stiffen its consistency. It should be added modestly as a little goes a long way. It will also reduce the gloss of an ink. 16 oz/100 g container

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.
