Addition To Comercial Glaze To Crackle?

07 January 2015 - 07:28 PM

Hi, is it possible to add something to commercial clear glaze to make it crackle?

 

and if I add a layer of regular glaze underneath the crackling glaze will it add more adhesion to it (sometimes may flake) or just get in the way of the crack effect?

 

Thanks! 


Firing Of Thinnslabs

12 October 2014 - 05:17 PM

Hi, I was doing 12'x12", 1//4" thick tiles (hearth clay, with and without grog, cone 04-06 using slab roller, electric kiln ) and firing each resting on each kiln shelf with good results ,

but the quantity to be fired is pretty limited.

 I try different tile setters but cracks and warping happened, even those tiles that were pre fired (or the second firing weakens them further!?)

 

I thought I could do porcelain(?) tiles 13x13, 1/2" thick to use as "shelves" so I can put more all- surface-supported tiles in the kiln. I also thought pre fired the "shelves"before putting them to work, metal would be the best but I know will melt... 

 

 

 do you have some suggestions for alternative kiln shelves?

I apologize for my massive ignorance   :o

 

Thanks
