They will break readily.


And eventually.  Maybe not today or tomorrow, but they're a ticking time bomb.



Classic love story. 


Girls meets bad boy glaze. 

Girl falls in love with bad boy.

Bad boy breaks her heart.


She tries to reform the bad boy.

Tries and tries to change him…. but it’s not in his nature, he’s a bad fit.


Girl needs to meet a nice suitable and well balanced boy.

Well suited boy won’t tear her apart and leave her in pieces.

hey Larry,


Clive Bowen multi nozzle slip trailer here, near the bottom of the page http://discover.gold...mic-decoration/  (totally looks like something you would make)

In Topic: Mixing Commercial Glazes To Create A Translucent

It might and it might not, only way to tell is to try it and see.


Another approach to take would be to take the clear glaze and add some stain of the same colour you like to it. You would have to weigh out the glaze and stain and take good notes so you can replicate it if it works.  trial and error

So I'm guessing that since you are bisque firing to approx cone 1 or 2 that this is earthenware?


Do you have a controller on the kiln? If you do I would slow down parts of the firing and speed up other parts. For thickish pieces I would use something like this:


candle overnight at 85C

25C per hour up to 120C

90C per hour up to 540C

then slow down to 40C per hour up to 600C

speed up again to 80C up to around 1000C

then slow it down again to 40C until you hit your final temp of 1140C


I wouldn't peek at 200C, leave the plugs in, go have a cup of tea, walk the dog, clean the studio, leave it alone until its about 90C then take the plugs out, but leave it be to cool down the rest of the way. Don't unload until the shelves are cool enough to pick up. (air temp inside kiln is a lot cooler than shelf temp).


+1 for what others have said about even drying.

Picture 1 damage is from the tile being fired before it was dry. Moisture in the clay blew it up, try candling the tiles overnight, kiln around 185F, before starting to increase temp slowly.


Picture 2, cracks could be from cooling too fast. Do you fire these pieces on something like silica sand so they can move in the kiln as they shrink? Few more questions though, what's your firing schedule, how fast does your kiln cool and at what temp do you crack the lid open? Also, the little piece that came away from the surface, I would guess it's from not having it joined really well or is the result of a second cooling dunt.
