AndreaB Posted January 29, 2017 Report Share Posted January 29, 2017 Hi everyone, I'm going to be doing a lot of hand building of porcelain, plates. platters. Should I bisque fire upside down (on rims), right way up, on kiln washed shelves or on calcite alumina? Thanks Andrea Link to comment Share on other sites More sharing options...
Roberta12 Posted January 29, 2017 Report Share Posted January 29, 2017 Andrea, I put mine directly on the shelf, on their bottoms. Maybe I should put them on their rims, but I am always concerned about the warping with porcelain. The dinner plates are 11 inches and I have a platter that is about 22 inches. And that is what I do for bisque. Roberta Link to comment Share on other sites More sharing options...
Mark C. Posted January 29, 2017 Report Share Posted January 29, 2017 I always fire all plates on their feet.Never on rims-sometimes draped over other forms or stuffed in sideways. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted January 29, 2017 Report Share Posted January 29, 2017 I fire them threes in a stack upright, if they are thrown, with a little grow in between. Handbuilt pieces may or may not stack depending if they are the same shape. Marcia Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted January 30, 2017 Report Share Posted January 30, 2017 How many plates do you have? Link to comment Share on other sites More sharing options...
neilestrick Posted January 30, 2017 Report Share Posted January 30, 2017 You can stack them as long as the weight is carried by the foot of the plates, not the rims. I usually stack mine in groups of 5 or 6. Link to comment Share on other sites More sharing options...
AndreaB Posted January 31, 2017 Author Report Share Posted January 31, 2017 Whoa you all take making plates seriously! I'm starting a hand building porcelain class with Antoinette Badenhorst next week and I've only done 1 slab piece to see how shrinkage affects the size. So in answer to your questions I'll only be making at the most 8 plates (my kiln is a front loader) and hopefully they will turn out to be stackable. I was just concerned about how stacking them would affect warpage since I've previously had quite a bit of warpage. Thanks for the info, I appreciate it. Have a good week Andrea Link to comment Share on other sites More sharing options...
neilestrick Posted February 1, 2017 Report Share Posted February 1, 2017 I the glaze firing, make sure your shelves are very flat, and don't rush the firing or the cooling. Link to comment Share on other sites More sharing options...
