Hello everybody! I am quite new to ceramics and I was wondering if it is possible to leave pieces unglazed. It concerns a series of handbuilt tealight holders, so even though it is functional pottery, they will not be used for any food or beverages. The types of clay I have used are the numbers 354 (980-1200 °C), 366 (1000-1120 °C) and 376 (max 1240 °C) from Have a good clay (I think it used to be called Goerg&Schneider). I like the structure and colour of the clay (especially when the tealight itself is lit and illuminates the chamotte) and I wish to keep it after firing the pieces. Is glazing a must for every piece of pottery? And if it is possible to leave them unglazed, should they be fired twice (and to which temperature)? Also, will the pieces be more brittle and fragile when they are not covered by the glaze? Thank you very much in advance! Any help is very welcome!:) Have a good day!

Hi, I am looking for some advise if possible. I fired my kiln last night but the kiln didn't reach full temperature. I looked at the cone I have in my cone stand and it is not melted. The cone in the sitter either melted or fell off and the kiln shut off. Can I re-fire? As I have not unloaded it, can I just turn it on? Thanks Mal

Please help me. I can’t figure out what stoneware clay my kiln could handle. I recently purchased the Jen Ken AF3C 11/9 Ceramic Kiln. It’s Max temp (as stated) is 2100* or about cone 3. The problem is I need a functional ceramic that’s not too porous so avoiding earthenware. Does anyone know what type of clay I can fire at the temp? Or am I coming at this problem the wrong way? Thank you so much for your help! -
I've got a small top loading kiln which states that the max firing temperature is 1000 degrees Celsius, however I really need to fire to Cone 6 (1240 ish). Is there any way a kiln can be converted or refurbished, or rewired in order for it to fire to a higher temperature?
