Old Brittle Ifb

Recommended Posts

The local school district sent an old 35 cubic foot to the warehouse. The bricks fell and broke into pieces. The pieces were loaded onto 3 pallets. I got 3 pallets of free pieces.

 

Has anyone used ground IFB to make a refractory? If so,

1. what recipe do you use?

2.To what size I should grind the brick?...gravel, 10-20 mesh?

After working on my kiln and ending up with a big bucket of collected dust and other broken bits I have been thinking the same. I want to try mixing with sodium silicate and seeing if you could make some kind of maybe slightly castable IFB. Not sure how much of the insulating they would lose.

Use it as the grog component in a castable recipe like this one: http://www.artistpotters.com/anagama/castable.htm

That is the very article I have and was planning on using its recipe... my after Christmas party will be crushing 400+ lbs of IFB. I'll post pics. At that point I will have everything for my kiln build. The kiln will be about 16 cf.

 

I'm excited.

I've had that link bookmarked since at least 2012.  It's funny how small the ceramics community really is.  I would have never guessed at a connection, but I'm not surprised--that seems to be the way things go.

Do you have access to a Soldner mixer? I've heard of some colleges making their own ceramic grog in one out of scrap bisque.

The Soldner Mixer is great for mixing clay, not so much for crushing fired clay. Jaw or plate mills are used to crush the aggregate prior to mixing.
