Vodka shot glasses "Gzhel style"

Vodka shot glasses.
At the end of the 20th century, I was involved in ceramics and made porcelain in the Gzhel style. It should be said, however, that since the manufacturing conditions were artisanal, this porcelain is not of very high quality: the shard (potsherd) is not white enough, and the glaze flow (spread) is not always ideal. And perhaps it would be more accurate to call it ceramics. But in my opinion, this does not detract from its artistic merits.
