Twenty-seven samples of transparent vessel glass fragments acquired during archaeological research at the Salm Palace in Prague were collected from two cesspits, marked as 2223 and 23. Cesspit 2223, which was richer in finds, can be dated from 1575 to 1800, while the archaeological finds from Cesspit 23 fall into the period from 1550 to 1700. The samples were analyzed using EPMA and LAICP-MS. Twenty-six of them correspond chemically to potassium-rich glasses, and the remaining sample corresponds to soda-ash glass. The potash and woodash glasses were produced locally, whereas chemical composition and appearance identify the soda-ash glass as an imported item. Three major groups can be distinguished using principal component analysis: soda-ash glass, potash glass, and wood-ash glass. The studied samples differ from glasses of the same date from Germany, Belgium, and Portugal, as well as from medieval Czech glasses.
