"Pit firing is the oldest known method for the firing of pottery. Examples have been dated as early as 29,000–25,000 BCE. Kilns have since replaced pit firing as the most widespread method of firing pottery, although the technique still finds limited use amongst certain studio potters. Unfired pots are nestled together in a pit in the ground and are then covered with combustible materials such as wood shavings, leaves, metal oxides, salts, sawdust and dried manure..." source

I'd love to pit-fire them, but I'm not sure about the result. Let it be an experiment.
Here are some examples of pit-fired pottery on Etsy >>
