This jar was thrown by me on the potter's wheel. I threw it as a closed bottle and then carefully cut off the top to create a lid. The dimple provides a little key to keep the lid more balanced. I glazed it simply with a traditional shino glaze on the inside and nothing over the clay outside. I chose to leave the exposed clay bare because this jar was headed for the wood kiln. The peak of the firing is over two thousand degrees, hot enough for the wood ash to melt into a swirling airborne glaze. You can see where it caught beautiful speckles of ash as well as some flashing in the clay from the open flame. This jar measures about 5.5"
