For a new pot, the firing process could leave some residual clay, which comes out while wiping. This does not get into food though, because we have tested it cooking plain white rice and steaming milk – both these ingredients can quickly take from what is next to it or added to it, but in both cases, we did not find clay mixed with food. So, we can confirm that this is only while wiping after washing for the first 1-2 times.  It is however important to note that our clay is even purer than food grown today and is composed of essential nutrients so there is nothing to worry about.

The clay residue will stop coming when wiping after a few uses.
