HI, I have a really long hairline crack in a sculpture that just came out of bisque fire :/ The crack is from the base to the neck, goes all the way through but very thin. Been doing research regarding Bisque fix, Mend it and paper clay. Looking for advise on which is better for hairline as cannot assure product completely fills the middle. Really want to glaze this to cone 6 without it separating even if I have to rebisque.,

Hi! I have been making pots for about 7 years and in the past 4 have struggled with small s-cracks appearing on the bottom of about 75% of my pots. The s-cracks are usually around a half inch long, thin, and only on the underside of the pot - never go all the way through and therefore the pots are all fully functional, just annoyingly cracked. In the photo attached, you'll see 3 cracked pots, and 2 planters that did not crack. My theory is that something is amiss in the center of my pots that causes stress & cracking during drying - because typically, when I make planters that have the cen -
Hello Community! :-) I am pretty new to ceramics and I am learning new things about this fantastic material on a daily basis. For my latest project I am trying to crack/break up old clay bottles with the principle of the heat shock. Does anyone have an idea what would happen, when I rapidly heat up a bottle (like the one in the picture) to 1800 degrees Fahrenheit ? My wish would be to let the bottle explode and to create many fragments. Is the wall of the bottle maybe too thick (approx. 4mm) to really burst into pieces? Will nothing happen or maybe just one big crack? Or do

Does this crack in the firebrick in the lid of my kiln need some kind of attention? I've been told both yes and no. It's a Shimpo DUA-15 kiln. Bob

Hello! I have recently made the transition from earthenware to stoneware to create mugs and dinnerware. I am fairly confident I applied the glaze to thickly to these mugs as I have made three and all three have small thin hairline cracks around the areas of thicker glaze... bummer.. a lesson learnt. I wonder if i can save these mugs though? The cracks are only on the outside surface there are no cracks to the bottom or inside. Shall I write them off (use might be dangerous) consider them seconds or try to repair the cracks? I have seen a few methods of repairing on google, I don't w

From the album: Handbuilding work
This lilypad plate is for under a frog planter I'm working on. It developed a small crack on the back during bisque however I wanted to test the glaze so went ahead and glazed it. The crack came to the front and lengthened during glaze firing but I really like the glaze. This was a slab rolled piece, handcut then embossed using one of the large ball Sculpey embossing tools .. I love those things! Other than the crack I'm really happy with this so I'll remake for the frog planter.
