I ordered some refractory cement a while back to fix up my old forge, but ended up getting a new forge instead. I thought I had ordered Satanite or the other similar cement, but when i finally read the label, I discovered that I had Mizzou castable refractory cement. Can this be used to coat blades and if so, what is the correct proportion of water to cement?
 
Joe, I don't think castable will work for clay coating the blade, it has large chunks in it more like concrete. You could try it but I don't think it'll stick or stay on the blade when heating. Satanite is what you want.
 
ah...makes sense that it would have some kind of aggregate in it.....oh well....time to find some satanite or furnace cement locally:grumpy:
 
Went to Lowes and Home Depot and got blanks stares. The "seasonal" aisle at Lowes contained Christmas lights, fake trees, portable outdoor heaters and compressed paper fireplace "logs". After all....I do live in central Florida....not much call for furnaces here and fireplaces only get used about a week every year on average. I ended up going down the street to my old faithful fireplace shop and got a 2 lb tub of Rutland Chimney Sweep furnace cement. It probably cost me more than if Lowes or HD had stocked it or if i had gone on the web, but hey......if you want something right away, you go to the experts and maybe pay a little more, but you get what you need.....reports to follow:thumbup:
 
You might try grinding some up real fine and then mixing it with water and trying it on a blade.
 
Contact Darren Ellis at Ellis knife supplies, he can fill about any order that has to do with forging supplies.:thumbup:

The Rutland gray cement is pre-mixed. I am using the furnace cement on Kevin Cashen's advice
