I bought some Japanese ceramics and drilled some holes in it to turn them as bonsai pots.
I would like to unglazed the inside of the pot.
First if I would like to do it is because all the ceramic glazed pots are not glazed inside. I am wondering why exactly, and I guess it is for better breathability?!
I am also wondering how can I remove it in the inside ?
I found out you can sand paper it with a 220 grit.
I tried it but by hand it seems to be to hard if not impossible.
Is there any product to help removing the glaze ? Has anyone ever tried it ?
Let me know your suggestions on the process to do it and if it is worth it or useless.
Thank you for you help
