This forge comes with
Superwool XTRA
insulation!
A
major generational leap
in the thermal blanket insulation industry.
It emits
ZERO
crystalline silica, and the fibers are
Low Bio-Persistent
.
Containing high heat safely has been an endeavor put forth before scientists, chemists, and engineers
for decades. The existing material used, Refractory Ceramic Fiber (RCF) Blanket, made from Kaolin, came
with negative health concerns. RCF, when heated above 1800°F, releases crystalline silica which are
hazardous to our respiratory system. The second health concern was the airborne fibers. RCF fibers are not
low bio-persistent, meaning they stay in the body for a long period of time, which could lead to health
issues.
When forging, temperatures reach well above 1800°F. Forge manufacturers for years would line the
forge with RCF Blankets. In our earlier generation forges, we included a liquid Rigidizer to harden the
blanket and Satanite Refractory to seal the fibers and that worked out great. However, we felt that the
forges we manufacture need to be many times safer for our customers.
Working with the Thermal Ceramics department at Morgan Advanced Materials in late 2021, we made
the decision to switch over to the new Superwool XTRA insulation blanket. The blanket is both a Low Bio-
Persistant and does not form crystalline silica when heated up. It is not classified as hazardous or
carcinogen. Morgan has been internally testing this product for 4 years with proven success.
We are the
first forge manufacturer in the world to use the Superwool XTRA insulation blanket.
It is much more
expensive but well worth the safety benefits! We are also still including the Rigidizer and Satanite
Refractory with our forges for our customers, to achieve that rock hard surface that they are used to.
Superwool XTRA has very high heat resistance characteristics, the working temperature is 1450°C
(2642°F) and max temperature is 1650°C (3002°F).
