gas forge info

[skip52]

The gas forge that I'm fabricating will be lined with Kaowool and coated with QF-180. Can the Kaowool be coated with a furnace cement to firm it up and provide a more ridgid surface for the QF-180. Thanks for any help. skip52

I'm not familiar with QF-180. Most of us coat our kaowool with satanite and then go over that with ITC-100..The ITC-100 is a refractory product that contains ceramics and will boosts the temp of the forge quite a bit, although it is a little pricy...

To find the products he mentioned check out Darren Ellis' site. www.refractory.elliscustomknifeworks.com. Hope this helps.

Here is the basic process. Line the forge with the wool. Apply rigidizer (colloidal silica) to the wool and let it dry. This stiffens the wool. Apply a 1/4" layre of satanite over the wool. This seals the wool fibers from becoming airborn, and increases the R factor. Finally add a coat of ITC-100 to give the inside a highly heat reflective surface. Darren Ellis' site has lots of info and FAQ about forge building, as well as all the supplies and parts you will need.

Ok,
The short answer is no. The black furnace cement is silicon base and it will melt over 2000F.
Thanks,

Hi Skip52w, As Stacey mentioned, if you want to ridigize the wool, you can use Instuff, else, the standard is to apply Satanite and then top coat with ITC-100 for efficiency. Let me know if I can help in any way!
