Thank you so much for all the detailed answers. In the studio I go to or the workshops I followed, we were never told about the hazard of dry clay, oxides etc. I'm planning on setting a small studio at my place, whether it's for me or the others I'd rather be too cautious than not enough. At least I know now that I have to use a respiratory mask when handling powders. I'll try to use stains as much as possible since they are less harmful.

Hello everyone, I started throwing last year but I didn't have a lot of time so I was on and off the wheel. I just bought my own wheel and now that I have a lot of spare time I will be focusing on throwing but also experimenting. I am thinking of making some colored clay to get some marble effects. A lot of potters use mason stains or oxides that they mix to wet or dry clay. But I was wondering about the food safety, let's say I am making a mug using a white and black (colored with manganese) clay, is it going to be food safe if I use a transparent glaze that is food safe ? When oxides are covered with an appropriate glaze, are there any risks ? Also, some people add mason stains and oxides to transparent or white glazes to color them, same question about food safety. As you can see I am too scared to poison anyone Thank you
