It goes from the top to the bottom, the ring is unglazed. this is a slab platter where I attached a slab ring to the back

Hello! I am in need of some advice. I will attach photos. A whole batch of my platters came out with a hairline crack directly going through the center. There is no cracks in the green ware/bisque ware stage but they sometime come out like this. Is this from the clear glaze? Is it cooling too fast?

Hello! I was recently gifted a china painting kiln. However, I want to use it to fire pottery. I am used to doing mid/high fire pottery so I am not sure what clay would work best with this temperature. I can fire to cone 022-06. The temperature of these kilns are not supposed to exceed 1800 degrees. When working with low fire clay I was taught to always bisque fire to a cone 04. When searching for the appropriate low fire clay, the results are always clay that should be bisqued at 04. I am guessing I should be doing my bisque fire at a cone 06 so those clays wouldn't work with my kiln? Could I then glaze fire also at cone 06 with low fire glaze? Do you have any suggestions on clay I can buy that would work well with these temperatures? My kiln is the Evenheat RM2 1210 120v Thank you for your help

Hello! I am an art teacher with a large background in ceramics. However I need a solution to this problem. My dear sweet mother purchased an Evenheat RM2 1210 Kiln 120v for me as a gift. As you may know, this kiln is a china painting kiln and should not be fired over 1800 degrees. I know nothing about this firing range or china painting. Unfortunately, when my mom bought me this kiln she did little to no research and just swiped her card. I cannot go back in time. This was a crazy expensive purchase and I do not want to be ungrateful so I want to try to make use of this. I called Evenheat and you cannot return the machine after 30 days (which it has been). I can fire between cones 022-06. I am looking for any and all advice. -Can I buy an easy solution in order to fire low fire pottery (04-06)? Or even change it to high fire if possible (4-6)? A high fire kiln is what I always wanted or -Can anyone recommend clay/glazes meant specifically for cones (022-06) I have always fired bisque at 04 and then my glazes at 05... What clay would be okay firing at 06-022? Could I just use my normal low fire glaze at 06? Thank you in advance
