The FS Series Shuttle Envelope Kilns are primarily designed for the firing of ceramic ware. Each furnace system includes two fixed stationary bases and a moving kiln that shuttles between the two bases. The stationary bases provide a stable platform for loading delicate ceramics. The base is easy to load because it can be loaded from all four sides once the kiln is shuttled out of the way. Normally the kiln is removed from the fired ware at a fairly high temperature for a fast cool down in the slowest part of the cooling curve. This greatly adds to the efficiency of the whole system. The entire kiln is built for heavy duty daily production and easy in-house maintenance.
