Founded in 1993 by Carl Firestone, Cadiz-based Fuse Tech repairs and maintains high-temperature industrial furnaces and their refractory linings using ceramic welding and other proprietary methods. Its specialty is performing many repairs while furnaces remain hot and operating, helping glass and coke producers extend furnace life without a full shutdown. Fuse Tech’s employees bring more than 150 years of combined ceramic-welding and refractory-repair experience, and the company mixes and tests its exclusive welding materials in-house.
