I make my pots from mid-range stoneware, and occasionally porcelain. I only use food-safe glazes (unless specifically noted in the pot's description), so all my pots are suited for daily food use.
They are microwave-safe and dishwasher-safe (unless specifically noted), but make sure you pack them with softer/plastic pieces around them in the dishwasher to reduce the chances of chipped edges.
My pots are not tested for oven use.
As a general rule, never put boiling water into a cold pot; instead, let the pot warm up to room temp or above before pouring in hot water.
If you run across an issue with your new pot, please don't hesitate to let me know. (I'm just a human; I make mistakes). I do not guarantee a refund or exchange, as all my work is handmade and therefore not always reproducible, but we can work out the issue on an individual basis and I'll do what I can to make it right. Just send me an email with a photo of the piece and a little info about it.
