Thank you for viewing. I purchased this a few years ago, but I ended up only using it two or three times and it's been sitting in the cupboard ever since, so I'm putting it up for sale. It is definitely compatible with gas. I'm not sure about IH... It's in beautiful condition as I haven't used it much. (Stains like patterns can be seen due to the lighting.) The depth is about 20cm. Instant purchase is welcome. I'd like to make it first-come, first-served ^_^ Thank you very much m(_ _)m
