I Forge Iron

What do I have?


Ethan Stone

Hundreds of companies made similar forges; if it doesn't have any markings the maker is up in the air.  A bit high price for one of those in that area and in that condition in my opinion; but it should pay for itself fairly quickly when in working condition.

60/40 mix of Portland cement and perlite or vermiculite.  Make some wire rings put a layer of the mix in put wire in then put mix on top of the wire. Form your ducks nest let dry and do a couple of slow heats to finish setting of mix. Mix should be more like mud.  Not to runny not to dry.

Portland cement dosnt make a good refractory, heat breaks it down (thats how they make it in the first place) alumina based cements are refractory. A tub of stove cement and vermiculite work, add water to make the cement thin enugh to coat the vermiculite, then paint with a couple of coats of plane stove cement. 

The problem is that any cement (or clay for that matter) will trap moisture under it and when combined with costics such as ash and cement it will rust the pan out. Sand and ash will to but they dry out must faster. 

Lining it with adobe is fast and cheap if you want a liner, and a heck of a lot easer to remove later.

Any locally available clay you can dig up Ethan, you only need it damp enough to mold into shape, just pliable, no wetter. As Charles stated bash it down with a mallet, or hammer, or lump of 2x2". Give it a chance to dry out and then fire it up, if it cracks, which it likely will, just plug the crack with a thumb full of the same clay and your good to go.......originally, forges and smelting furnaces where build of clay. Simple, effective, cheap.

They are doing some road works opposite my home this week, I'll be over when they start digging to see if I can find a bucket full or two myself for later use...why dig it up myself when they are already doing it!.

(Hopefully someone will ask why I want it and start a conversation, then with a bit of luck I'll score some sand, scraps of metal, broken tools.......) .

xxxx disapearing post bug!

Adobe is clay soil you build houses out off.

10-30% clay 30-90% sand. 

If you want to buy it, buy fire clay from a good building center and mix it 1 part clay to 2 parts sand. If you want to get fancy wet it with waterglass (a saterated solition od sodiumsilicat in water)

More than 1/2 the peaple in the world live in adobe, cob or ramed earth houses.

Don't get fancy, cement of any kind is WAY not good. Just ram some damp clay in the forge an inch or so deep. It's ONLY purpose is to distribute heat, it's not a heat shield, just spreads it out some. Cast iron doesn't LIKE spot heating and can heat check it also doesn't like shock cooling, say dumping water on your fire. All claying does is spread the HOT and slow the chill. Adding perlite or ANY insulation is a complete waste of money. You're NOT making an oven, it's just a fire place. Literally.

Heck, spot heat on a sheet steel forge pan will cause warping.

Charles's ratio is about right but anywhere close is good.1-3pts sand to 1pt clay. It isn't brain science or rocket chemistry, a good portion of sand allows the clay to expand and contract with minimum checking (cracking). If you use straight clay it WILL check but that's no big deal, not even a hassle just put a little dry dirt in the cracks and it's good.
