A gluten free kitchen question?

I know I need to get rid of non-stick cook ware, wooden utensils, plastic items, wooden cutting boards and the colander... I'm wondering if I need to stop using my pottery as well? Specifically I have an older McCoy mixing bowl that belonged to my mother, it's part of the oven ware set. I'm definitely not going to throw it away in any case-- but is it safe to put gluten free food in? Would there be a problem with cross contamination?
