Beebop Posted October 24, 2021 Report Share Posted October 24, 2021 I am thinking of trying out saggar firing at mid-temp in an electric kiln to create an anoxic environment, and possibly for some other effects as well. I’m not sure what kind of clay to use to make saggars that don’t need to be replaced after a few firings. Should I use ^10 clay? I see Laguna has a ^6 flame ware clay for making cookware, would that be a good way to go? Would grog make a difference? Should I just expect that no matter the clay, they will need to be replaced frequently? Is it just a bad idea all together? Can’t seem to find much about this online. Any and all advice on making and firing with saggars also welcome! Thanks! Link to comment Share on other sites More sharing options...

JohnnyK Posted October 24, 2021 Report Share Posted October 24, 2021 During my college Raku class we were required to build saggars and we used ^10 Laguna Soldate 60 which is a grogged clay and it worked out pretty well...I don't remember what cone the saggars were fired at, probably ^10, definitely gas.

Callie Beller Diesel Posted October 24, 2021 Report Share Posted October 24, 2021 I’d find something refractory like fireclay, and mix in some grog. Something that’ll hold up to a lot of refiring. Link to comment Share on other sites More sharing options...

Mark C. Posted November 1, 2021 Report Share Posted November 1, 2021 You want a open groggy clay body-and for added durability wedge in some fireclay10-20-% (you can buy this at any ceramic outlet) type does dot matter. I would use cone 10 clay like the soldate mentioned above or any really groggy cone 10 clay. The clay will not vitrify and thats good for a sagger.The more grog in the clay the better.
