I love this part of my process. I spread out all of my test tiles (both glaze and terra sigillata) on my work table and create combinations that I’ll use on my #pottery. The four tiles to the right are one of the color combos I picked out. I wrote about the process of converting foraged #WildClay samples to terra sigillata (refined decorating slip) in this blogpost: “Earthen Rainbow: Decorating with Clay” https://potterybyosa.com/blogs/clay-people/earthen-rainbow-working-with-wild-clay-terra-sigillata-at-midrange
