Description:

June 3, 2015 30.5 months continuous use with one set of Kanthal elements. The elements were still good but the crucible finally gave out. Spectrum Nuggets Spruce Pine Batch/Nuggets Uroboros Cullet Bullseye Cullet Furnace design lowers energy costs Extends life of glass Lower melting temperatures = lower energy cost Steel locking Wheels Complete furnace and crucible ready to melt available Furnaces in stock. As of March 29, 2015 one set of elements fired a 100# crucible for 30.5 months of continuous melt of Spectrum Premium Nuggets. The mullite crucible finally gave up, but the elements were still good! This 30.5 months continuous use from a set of 9 Kanthal elements is due to engineered hard refractory element holders which show no signs of wear after 5 years of continuous use! The mullite crucible lasted 30 and a half months. All of this is due to even temperature inside the furnace is transferred to the center of the crucible. Lowering the temperature improves the glass quality, lowers the cost and lengthens life of the elements and crucible. Furnace design functions are as close to worry free as you can get. Owners of this furnace say that they were never able to have a natural gas furnace or propane furnace run continuously for 2 years! Here in the Northwest where our electricity is inexpensive, the cost per day to run this furnace is $8.00. Less than $250 a month. Less than $3000 a year. The cost per day of melting glass in this furnace is minimal compared to firing your glory hole and less than cost of your electric preheat kiln(s), annealer(s), lights, stereo, and refrigerator. Any glass furnace, gas or electric, will shut down when the power goes out. The recommendation for this furnace when that happens, is to get all the glass out of the crucible before the temperature drops to 1500 degrees F. Then close up the furnace and wait for the power to come back on. Proceed from the temperature when the power comes back on to 1500 degrees at no more than 100 degrees per hour. The crucible and elements in this furnace are still working today after 24 months and having successfully survived power outages three times. Another furnace dropped fully charged when the power went out the furnace was down to 1200 degrees F before the power came back on. That crucible survived by raising the temperature 50 degrees per hour to 1750 degrees and then to melting temperature. In both cases the glass was not of good blowing quality, but could be used for other techniques. The important thing is the furnace and crucible continued to function without damage. You can take the time, effort, and build your own. This one is proven and ready to go. Is your goal to build a glass furnace or to blow glass? The image on the left shows the evolution of the efficiency disadvantage of having corners in a glass furnace. Arching the roof, side firing across the door and adding a flue to a gas furnace greatly improves efficiency through design. Another development was shaping the furnace round with a dome rather than an arch. More work to build but much more efficient. Columbia Electric Glass Furnace continued next page
