I seem to recall one or two doing this. But i suspect the reason they don't is cause they don't need to.
They all have a pot already. The benefits of more pots seems low. Conversely the calorie cost seems high (if only just collecting clay and cutting wood to fire it.)
On Alone thd priorities are shelter and food. Clay pots seems like a luxury in terms of utility use and energy cost.
This is the correct answer. Alone is not really a how to live in the woods show, it's a managed starvation show. The contestants are limited to about a 1 sq mile area which may or may not have a good source of clay. They purposely set them out just a few weeks before winter so they do not have a long time to prep. Conserving and replenishing calories is the name of the game.
