History of Blooming

Blooming, a popular finishing technique for karat gold jewelry from 1870 to 1890, was first documented in 1853. The means for creating a bloom finish involved dipping a karat into a boiling mixture of hydrochloric acid (muriatic acid), saltpeter (potassium nitrate), salt and water. This process burned off any alloys on the surface resulting in an alloy-free, thin layer of soft, pure gold on the item.
