jrgpots Posted December 20, 2015 Report Share Posted December 20, 2015 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? Jed Link to comment Share on other sites More sharing options...
Mark C. Posted December 20, 2015 Report Share Posted December 20, 2015 When you get this process mastered please let me know as I have a lot of broken soft bricks. The glue/cement may be the key. Link to comment Share on other sites More sharing options...
High Bridge Pottery Posted December 20, 2015 Report Share Posted December 20, 2015 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.

Tyler Miller Posted December 20, 2015 Report Share Posted December 20, 2015 Use it as the grog component in a castable recipe like this one: http://www.artistpotters.com/anagama/castable.htm Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted December 20, 2015 Report Share Posted December 20, 2015 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. Link to comment Share on other sites More sharing options...

Marcia 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. Link to comment Share on other sites More sharing options...
Colby Charpentier Posted December 21, 2015 Report Share Posted December 21, 2015 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. Link to comment Share on other sites More sharing options...
ronfire Posted December 22, 2015 Report Share Posted December 22, 2015 What about a cement mixer with a couple of steel chunks to help break it up. There are lots of cheap used mixers available. Link to comment Share on other sites More sharing options...
