For those that build and built day tanks the Corhart AZS liner was an ideal refractory. It was long lasting, had only two seams, had no sharp corners, and was only 3 pieces as shown in the photos and diagrams. The center section came in 3 sizes so one could build a furnace of varying capacities. This liner is available once more and can be purchased through this web site. If you're interested in purchasing the liner contact me or download the pdf files found at the bottom of this page and E-mail your request to me. Please Include your shipping address and port of entry if you know it. The charges include shipping and delivery to your studio.
We can supply the Corhart design in 200 kg., 300 kg. and 400 kg. capacities

It is important to heavily insulate the AZS Glass Tank as part of the furnace design. This insulation not only saves energy (and dollars) but it also helps to dampen the effect of normal temperature fluctuations, thereby lessening the potential for thermal shock (cracking) of the fused cast material.
During the melting of your glass batch or glass cullet, we suggest several small charges rather than one large charge. This practice will dampen the severity of the temperature swings in the melter, and minimize the thermal shock to the refractories.
Tank depths greater than 12 inches can be supplied.
Position 2 is the center block and is available in three sizes. The photo above should give you an idea of how this liner is constructed.
The estimate of the glass capacity is based on soda/lime glass with a cu. ft. weight of 160 lbs. I have built 4 furnaces using this block and each lasted 7 years of continuous use in a university environment. The life expectancy of any furnace is dependent on a number of factors. The primary factors are: Type of glass used (batch or cullet), melting and working temperature, number of charges per week, how active your glass is (viscosity). Regardless, an AZS liner when used correctly will outlast any other type of liner.

How to Calculate the Glass Capacity of a Day Tank
▪ Length x Width x Height in inches.
▪ Divide the answer by 1728 (cube root)
▪ The answer is the dimension of your furnace in cubic feet.
▪ Multiply the cubic feet by 160 (weight of soda/lime glass pre cu. ft.)
▪ The answer is the capacity of your furnace in pounds of glass.
If you want the answer in Kilo capacity divide the pounds by 2.2
