While I’m not a ceramicist, but have done some calligraphy, the gold
is most likely 23 K. gold leaf, which is still available today in
sheet or patent form; from better art stores or online. Do not buy
composite gold leaf, as it’s not real gold, but is used for picture
frame gold leafing.
The gold leaf is applied using a sizing, and burnished onto the
surface. If you are removing overall paint, you probably cannot
easily remove it without removing the gold leaf as well, depending on
However, due to the age of the piece, I agree with the other list
member… contact a qualified restorer or museum before further
damage is done to the piece that may be irreversible.
Good luck, Marsha Greene
