Gamblin : Magnesium Carbonate : 100g

Traditionally used to stiffen ink, Magnesium Carbonate can reduce the gloss level of ink and when added to ink it becomes transparent - there will be no alteration of color of the ink. It is recommended that it is added in small amounts at a time - little is needed to add body to an ink. Magnesium Carbonate can be used with both Etching and Relief Inks. Mix well and keep away from excessive heat.
