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 diagram below. 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 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 final estimate will include crating and shipping charges to the port of entry. There is an extra charge for delivery to your studio.
These two photos should give you an idea of the the quality of the liner.
If a day tank is your furnace of choice then an AZS liner is what you should be using.
When ordering keep in mind that these liners are made to order and there is at least a 10 week lead time.

The AZS style Glass Tank is designed primarily for the glass artist who desires 300 - 500 lb. melts. The AZS family of shapes consists of end pieces and an 18" wide x 12" to 22" middle channel section with 2 joints. If you want more capacity than this, we suggest using two pieces of channel between the end pieces.
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.

Position 1 is the end cap (101-8). In order to construct this furnace you will need two of these. 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. It should be noted that this type of liner makes the building of a continuous take fairly easy. The great advantage to this liner beside long life is there are only two seams. 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. 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.

The initial expense of an AZS liner is more than compensated for when you consider its life expectancy. Real world experience tells us that an AZS liner will last 5 to 7 years. The life expectance of any liner is also dependent on how many charges one makes per week. The life of a high alumina liner is at best 2 years or less if you melt batch. It should be noted that the AZS liner is not recommended for use in areas that have frequent power outages.
