Emanuel Ciner was instrumental in pioneering many of the technical innovations that made the creation of high-quality costume jewelry possible. He worked to perfect and popularize the use of ‘white metal,’ which was a strong but workable blend of tin and other metals more popularly known as jeweler’s metal. He also worked to master induction casting and developed a special kind of rubber needed to make molds that could stand up to heated, liquid metals.
When Ciner first entered the market, costume jewelry was sand cast, an inferior molding process that produced bumpy, inconsistent pieces. To create a better quality product, Emanuel Ciner knew he would have to revolutionize the mold making process. He found the method that would solve his problem by talking with his dentist! Working side by side with his son, Irwin during these days of experimentation, he modified the method utilized by his dentist to make inlays in order to create quality molds for his jewelry.
To mimic the casting process used to make dental inlays for jewelry manufacturing, they had to have something far stronger than the plaster and wax molds used in dental processes — and this led to experimenting and later working to perfect a special vulcanized rubber. The methods Emanuel Ciner developed o create laid the foundation for the way much fine and quality fashion jewelry is manufactured to this day.
