Porcelain buy "Pit Fired" Necklace

"Pit Fired" porcelain pendant on leather thong with clasp
Pit firing is the word's oldest ceramic firing technique and involves multiple coatings and polishing of Terra Sigilatta slips prior to bisque firing for a smooth shine and then applying a wide variety of organic & non organic materials to create patterns when fired overnight in a pit buy with a fire built on top
Here I've used a masking slip which cracks during firing and allows the pattern to form
