One of the challenges of making jewelry out of "journeyed" broken pottery is just the process of getting it ready to be cut. Thankfully, we have a shed and part of a tent full of pottery that volunteers have collected since the tsunami. But it is all dirty and unsorted.
We have a staff member who works hard -- outside most of the time -- in getting the shards and pottery ready to be made into jewelry. She washes it, sorts it, and cuts it into suitable-sized pieces to be ready for the grinding room.
