  1. 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!
  2. Hi all, Happy New Year to everyone! I'm interested in firing stoneware dishes without using a glaze. I only want to use coloured slips. Would this still be food safe? I spoke to a potter at a rather prestigious ceramics event in London and she didn't use any glazes. I asked her if her ware was foodsafe and she told me, yes. I'm guessing that the high-fire temperatures will vitrify the clay sufficiently to make it washable/hygienic/easy-to-clean? One of the reasons I want to do this is so I can stack the shallow dishes on top of each other during the firing - but I also like matt finishes. I know there are matt glazes available but if I can skip this part, it would make my life a bit easier...and cheaper! Thank you in advance
