Founded by John R. B. Ransom to provide supplies, instruments and furniture for barbers, doctors and dentists.
Thaddius R. Randolph became partner.
The Ransom & Randolph Co. was incorporated.
Our primary business focus changed as we developed many revolutionary products for dental, industrial, jewelry and ceramic shell investment casting applications. These products included:
Investment for casting gold dental inlays
The first vacuum casting appliance
Industrial solid mold investments for World War II production
The first high temperature, water-based investment for ferrous metals
Ultra-Vest® investment for jewelry casting
Primcote® binder, the first ready-mixed, high performance primary binder
Deluxcote® concentrate, the first coat-reducing, fiber-based backup binder
Purchased by Dentsply Sirona (NASDAQ: XRAY), an industry-leading supplier of innovative dental products and technology, and began operating as a wholly owned subsidiary of Dentsply Sirona. At this time, we began distributing ceramic shell binders and refractories.
