Drinking glass (3) - Crystal - Kasteleinsglas

Three rare antique kasteleinsglaasjes, also known as toastmaster glasses.
These glasses are heavy and, because of the thick base, hold only a small amount, which meant the innkeeper could lift the glass without getting drunk. They are handmade and mouth-blown and date from around the early 19th century.
The glasses feature a ground and polished pontil. The glasses are in good condition; one glass has a small chip on the rim.
