The butter dish is slip cast from porcelain and glazed with a yellow salt glaze. The iron specs in the glaze come out as brown spots in the creamy yellow.
I made the original myself and made the mold out of plaster. I then used porcelain slip that I had made from porcelain clay to cast the two pieces. Once they had been bisque fired, I glazed them and then they were glaze fired to cone 10.
The high heat from the glaze firing caused many of the base pieces to warp. This one is slightly warped as well but holds the top in place as can be seen in the picture.
Even though this butter dish is made from a mold the firing and glazing processes cause each on of these to be a unique piece of art.
If you live outside of the USA and are interested in this piece I will work up the cost of shipping for you. Just let me know.
If the final cost of shipping is less that what I quote, the difference will be refunded to you.
