In 1963, Hotwork developed the original glass Furnace Heatup technology, termed Forced Convective Heating, and since that time has brought on-line well over 10,000 glass furnaces worldwide. It is now the accepted world standard for heating glass furnaces, with over 400 sets of portable heating equipment and 80 full time, highly trained technicians strategically located around the world to service the glass manufacturing industry.

Over the years, the service was expanded to include dust-free Cullet Filling, Expansion Control Supervision, Furnace Draining, Crown Rise Monitoring and Recording, Sulfate Removal, "Hold Hots" and a variety of other services to reduce downtime and enhance furnace campaign life and efficiency.

A safe yet fast glass furnace heatup using the Hotwork technology will ensure the integrity of the furnace refractory to maximize campaign life. A controlled temperature cooldown using the Hotwork method is performed when refractories are to be reused during a subsequent campaign or when a detailed inspection of the furnace is required.
