O/T again... Granulated Charcoal question

[Ken_Shea]

Some ideas on what granulated charcoal can be used for by individuals or the HSM?

Please don't ask why I am asking, it has nothing to do with 1800 pounds of it

Case and/or color case hardening.

[Rich Carlstedt]

Water filtration.
Takes out oders and almost all chemicals, even Chlorine.

Jim, that is a very interesting suggestion, can you expand on the process a bit?

Rich, there seems to be a number of types designed for different tasks, not sure what type it is as yet.
Have even read food grade type.

Ken, an important question. Is it granulated charcoal, (charcoal crushed and screened to a size,) or granulated ACTIVATED charcoal, (charcoal that has been treated with steam during the charing process?) Either one can be used for pack case hardening, but only the activated kind will do much for removing taste and odors or color from water. It will also smooth out "white lightning." Duffy

I was thinking fuel for a aluminum melting furnace or possibly even a forge.

Duffy, not sure as yet what type it is, should get it picked up by next week. Am hoping it is the activated type though.

Couldn't say no to the 45 40lb bags though, $25

Metal melting/forging you want 3/4" or larger pieces,otherwise it glows and blows(lights and then flys all over the place)due to the draft air.

In a nutshell, you pack the parts to be hardened in a closed container filled with the charcoal. Heat to ~1300-1400 degrees F and hold for a half hour or so, then dump into a water quench.

In practice, it is more involved, but that is basic pack hardening. For colors, bone charcoal is added to the mix, other organic charcoals such as leather are used as well.
