Biglou13 Posted June 5, 2014 Report Share Posted June 5, 2014 This is probably a John b? First it's vitrified. It's wood fired with some grog. I think this clay is mostly laguna 900, or possibly a mutt mix of wood fired clays. Looks a bit bizen like. Picture to follow. While it's not hagi ware. I understand that if a piece of hagi-yaki piece continues to leak there are remedies. Like the starch or rice gruel treatments I had/ have beer in mind with this piece What is your technique / recipe for sealing I'll make more but it's a 2 to 6 month turn around time for for me to get woodfired pieces back. And I'm interested in the japanese way to seal even though it's not hagi ware. Link to comment Share on other sites More sharing options...
bciskepottery Posted June 5, 2014 Report Share Posted June 5, 2014 This thread has potential . . . so, just how does a vitrified clay body leak? Link to comment Share on other sites More sharing options...
neilestrick Posted June 5, 2014 Report Share Posted June 5, 2014 So it has a crack in it? Link to comment Share on other sites More sharing options...
Biglou13 Posted June 5, 2014 Author Report Share Posted June 5, 2014 It wood fired. It more so seeps than full on leaks. By the time I finished the beer the coaster was not fully wet. It's laguna #900 the cone pack I saw cone 11 was down. Not sure where my cup was in kiln. Or where cone pack was. No crack but I haven't looked with magnification. I know the the grog, granite chunks. can cause small cracks in woodfire. This piece has some grog in it, not aggressive amount. Didn't see any iron spots on bottom. 3 other cups are holding water, less to no grog. I was told it was a shorter firing. And lack of, very little natural ash glaze on some pieces also proves it. Was a shorter firing, well known clay body. So I doubt it's a cristabolite issue Link to comment Share on other sites More sharing options...
PSC Posted June 5, 2014 Report Share Posted June 5, 2014 What does it sound like when you tap it with a finger nail...does sing or is it a clinker? Clinker means cracked. Link to comment Share on other sites More sharing options...

neilestrick Posted June 5, 2014 Report Share Posted June 5, 2014 It must have some sort of hairline crack in it, or series of tiny cracks. I wouldn't mess with trying to seal it up. 75% success rate from a wood kiln is pretty good! Next time put a liner glaze in it. Link to comment Share on other sites More sharing options...
