Hi, thanks for the question. Pretty much any type of clay is going to be suitable for ovens and high heat as long as your glazes are food safe. You have to keep in mind that most clays are fired to 2200 degrees plus if your firing cone 6 and 2350 if your firing Cone 10. So we know that clays can withstand some pretty hot temperatures. The key factor is what temp your clay "matures" or "vitrifies" at, making it non porous. 450 in an oven is nothing to be concerned about. B-Mix is pretty standard and usually just a formulation of porcelain mixed with ball clay.
An electric heat gun can bring your clay to a more sturdy leather hard in short order. Also, lifting up on your bat while tooling is an easy way to check your pots weight to gage clay thickness.
Very nicely slanted plate
Thanks for the video. Do you have to use any certain clay for items that are intended for the oven? I use mostly B-Mix.

@@RedCirclePottery thanks for the well thought out answer. That is what I suspected but had seen some things that made me wonder.
