Deltech glass melt furnaces withstand the harshest environmental and cycling conditions.
They were initially intended for use in a national lab research setup, where the furnaces were constantly used and operated with a variety of glass formulas. Today, these furnaces are frequently employed in government labs, universities, and industry settings to conduct research and development on bio, optical, nuclear waste containment, and other specialty glasses.

Get the Right Furnace
Not all furnaces are appropriate for melting glass. The compositions of many glasses are corrosive, and their fumes and splatter can damage fiberboard linings and heating elements within the furnace. Deltech's RS ceramic lining, developed with Sandia National Glass Labs through more than a decade of research, is the ideal lining for glass melting.
Deltech has also developed countless accessories including bubblers, multiple types of stirring mechanisms, tilt casting, and inclusion of downspouts to allow flowing glass at temperatures up to 1800 C. They have the ability to customize a glass melting furnace to your exact process, as they have done with many R&D facilities and many of the largest glass producing companies in the world. This allows Deltech to provide bespoke furnaces capable of producing the world's most complex glasses.

Deltech's glass furnace models offer numerous advantages to meet the glass melting needs. These benefits result in high-quality products, enhanced glass production, and safer operational practices. The furnaces can reach temperatures of up to 1800 ºC and are equipped with a ceramic lining to withstand glass corrosion.
The glass melting furnaces are engineered to remain idle at elevated temperatures and facilitate the rapid dropping of the bottom for swift quenching. The substantial thermal mass of the hot zone ensures quick recovery following the quenching process.
A ceramic split plug and ceramic top cylinder provide convenient access for a stir rod while safeguarding the furnace roof and top opening from corrosive substances.
A variety of optional features can be suggested or chosen by the user. Deltech's optional glass furnace features include:
- Automated functionalities such as melt pours
- Manual or programmable stirring systems for glass fining
- Sight ports
- Drain plugs to assist with cooling
- Spill traps replacing hearth plates to contain minor glass spills
- Element protection liners
- Kiln cars
- "Atmosphere envelope" designs for processes requiring inert atmospheres
