I also bought a purple sand electric stewing cup from Xiao Xiong. Later, I asked someone who ran to Xiao Xiong, and she said that it was actually just ceramic pot, and it wouldn't matter. You can go and see it now. The same model is still on sale, but the products sold have been renamed ceramic electric cookers.

I asked if the purple sand was changed to ceramics after the problem, and she said that it had always been a ceramic pot.

So what we are facing is probably that they sold ceramic pot as a purple casserole from the beginning, but this is a mistake.
