Summary of new furnaces

A range of front and top loading muffle and chamber furnaces for laboratory and workshop or studio use are described here. Three types of top loading furnaces are listed. There are those designed for use with crucibles for metal or glass melting, simple vertical rectangular shaft furnaces for general use and large flat furnaces for annealing, fusing and bending glass sheets.
Bogie hearth kilns are also shown.
Units of other sizes, types and operating temperatures can be built to order. All the furnaces are electrically heated.
