Firing is such a crucial part of the ceramic making which I don't know much about yet but hope this will change soon. I saw this book at the studio and given the age of the book, published in 1968, there were some very old images of potters and kilns.
This is such an old image of a pottery workshop... people don't dress like this anymore in Korea. This is probably around 1950s or before. It reminds me of my grandmother... she wasn't a potter but the country life.
