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!
