[TheForge] ITC 213 and beyond

Thanks Frosty.
Don Fogg and Chuck Patrick put on a marathon clay heat treating demo at the 
BBS last week. They were heat treating swords using Don's latest design heat 
treating forge
. It was a 55gal steel drum with a 2" X 4" door at the top of each end and 
an atmospheric burned idling at the bottom of one end. The1" kaowool liner 
was held in place with Nichrome wire, and the kaowool was not coated as he 
heat treats his 1095 blades at 1425 F.
Don used a digital read out thermocouple to regulate the temperature.
He told me that it the interior temp was the most uniform of any of the 
forges he has built, and large enough to treat the whole blade a one time.
Considering that he has built more than 55 forges and he tried every 
variation of multiple burners,this is a pretty good recommendation.

>> Jerry,

>> WWW.advacedmaterials.us

>> more refractory than zirconia) and the largest grain size is less than
>> .5µm--pure colloidal zirconia. Keep it dry and do not let it freeze as 
>> you
>> don't want it to cake.
>> That is a good price for such a refined product. You can also find #200

>> bentonite
