Hello, I am new to this community and to pottery/ceramic topic and I really appreciate if anyone could help answer my question.
I recently purchased a Sri Lanka teapot from Studio M, a brand from Marumitsu Poterie, Japan(https://www.marumitsu.jp/webstore/srilanka-l2395/?sl=en) And it’s purposefully made so that it looks a used ceramic teapot. So on their website, it’s mentioned that the glaze color is supposed to have strong irregularity. However, I found it odd to see those glossy spot/speckles on the semi-matte finish. Does anyone know what has caused those metallic, shiny, glossy greyish spot out of the supposed white-yellowish-brownish glaze?
Thanks in advance and really appreciate your help!
