Brian: Great! I wish there was a central location for this type info at permies! What do you have on Duraboard?
I want to use a rigid insulation between my RMH and straw wall. The RMH is 1' away from the wall. I've been looking for all types of ridged insulation and it's all pretty expensive. Regular fiberglass insulation is rated to 1200 degrees. Do you think that would be enough to keep my wall from going up in flames?

Thanks Brian
I'm in Illinois and called a number of home depot and lowes stores and no one carries the fireclay here. Finally, after an hour of being on the phone I called H.C. Muddox in Sacramento, CA. and spoke to a representative who said 'FYI' they don't call it fireclay anymore because it doesn't have a fire rating. He said "It's basically just ground up dirt" and asked what I was planning on using it for. I explained that I was going to cast a firebox and he said mixing furnace cement with any good clay would achieve the same result. He gave me the number for Basilite Co. which is a distributor for Muddox's product, now called 'mortar clay' and I will call them but I will probably end up experimenting with some local clay, perlite, fiberglass strands and fire cement to form a castable core.

F.Y.I. Almost all of the fire brick out there right now is the heavier 7 pound a brick at 9'' X 4.5'' X 2.5'', what we want is the much lighter 28 -30 ounce 9'' X 4.5'' X 2.5'' brick and
the 1/2 size 'split' 9'' X 4.5'' X 1.25'', ether get them to show you in the manufactures listing where it gives the weight, or take a full one quart milk jug with you and give them the
free hand balance test ! Think like fire, flow like a gas, don't be the Marshmallow! As always your comments, and questions are welcome and Solicited ! PYRO - Logically BIG AL !

follow up: I talked with someone at Basilite in California; she said Muddox is a "sister" company, was somewhat surprised that a maddox guy would say the fireclay was 'ground up dirt' but couldn't find a spec sheet on it and took my number and said someone would call me. I'd like to know how the product compares with regular clay.

I'm building a reel to reel electric furnace 6 meters long as well as two 24" cubic muffle furnaces, so I've found a few places to add to this list.

Cheapest furnace mortar is on Amazon: http://www.amazon.com/MEECOS-DEVIL-611-Refractory-Cement/dp/B002OU2Y62/ref=pd_sbs_petsupplies_6

Insulating fire bricks are cheapest if you live near the supplier. Best supplier in the Northeast: http://www.ceramaterials.com/insulatingfirebrick.html $2.10 per brick
This place also has a great price on ceramic blankets if you live near enough for shipping to not cause an issue.

High temp wire and ring terminals both are cheapest on Amazon.

Heating elements are cheapest on eBay (search furnace wire).

Good temperature control unit for a good price: http://www.ebay.com/itm/AC-110-240V-Digital-PID-Temperature-controller-25A-SSR-K-thermocouple-Sensor/141021325676?rt=nc&_trksid=p2047675.m1851&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D261%26meid%3D2824700559778313667%26pid%3D100005%26prg%3D1088%26rk%3D3%26rkt%3D5%26sd%3D330897116869%26
I'm using three on my reel to reel furnace (three zone heating) and one on each of my other two furnaces. I have an additional three lab scale muffle furnaces that are powered by this same controller. I've been using it for years with no troubles.

Hope this helps someone!
