Clay with batch codes 24MAY001-24MAY089 may contain a small plastic piece of PVC pipe. We found a small (less than 1″ by 1/4″ piece), determined the source and approximate point of contamination and were able to determine that there may be about 10 more pieces of that size across the 88 batches (roughly 125,000#) in this range. They are most likely to be found in the earlier batches in this range, but in an abundance of caution, we wanted to widen the notice. We do not believe the pieces will cause harm to the potter, but may interfere with process. Should you find a piece of the contaminant, please do fill out this form and let us know whether you would prefer a credit or replacement. We do sincerely apologize for the trouble.
