mordant

• “The technique, attributed to Cornelis Drebbel, used a tin mordant to brighten the color produced by cochineal. 11 The discovery, as reported in the eighteenth century, was a fortuitous accident similar to that of Prussian blue; fortunate in that the discovery happened to someone able to recognize and exploit it. reference Drebbel, it was said, accidentally broke a container of tin-infused aqua regia over a container of the cochineal extract used in making thermometers.”

  The Creation of Color in Eighteenth-Century Europe

• “In the case of Cornelis Drebbel, who invented a bright red dye color by mixing cochineal with a tin mordant, we cannot prove that the inspiration for the invention was directly related to this production method for gold purples, but, even if the connection is only circumstantial, it is a circumstance we cannot completely ignore.”

• “A mordant is a substance which has an affinity for, or which can penetrate, the fiber to be colored, and which possesses the power of combining with the dyestuff and thus forming an insoluble compound upon the fiber.”
