To prepare carmine, the powdered scale insect bodies are boiled in ammonia or a sodium carbonate solution, the insoluble matter is removed by filtering, and alum is added to the clear salt solution of carminic acid to precipitate the red aluminium salt, called carmine lake or crimson lake.ther methods for the production of carmine dye are in use, in which egg white, fish glue, or gelatin is sometimes added before the precipitation. The quality of carmine is affected by the temperature and the degree of illumination during its preparation, sunlight being requisite for the production of a brilliant hue.
