This is larger version of the 15-pound electric furnace design. Fourty pounds may not seem like very much glass, but it is enough for several hours production work, making sculpted or blown items.  This design is perfect for the glassblower who wants to have regular access to hot glass for only a few dollars a day in energy cost.   Top-gathered furnaces like this are ideal for making patterned or plain pulled cane, paperweights and blown ornaments, where color can be placed on the top surface of the molten glass, and carefully picked up on the gather. This is a very useful technique which is difficult if not impossible to do accurately in a larger side-gathered furnace.

This has been a great furnace for me.  I use it for blowing vases and balls, making flowers, leaves, napkin rings, paperweights, marbles, hanging suncatcher ornaments, canes & millefiori, off-hand sculpted items.  It is the perfect size to use for learning and production.  It cost around $1,200 to build in 2001.  That includes the controller, elements and crucible.

The first 2-hr video segment covers the design and assembly of the unit, the second segment covers the controller wiring, use and maintenance. There are also several demos of the types of things the unit can be used for in a hobby or production shop environment.

Included with the DVD’s are suppliers’ list and parts list.  PDF parts list included here.
