The Chribska glassworks, full name Sklarna Chribska, was founded in the early fifteenth century, and stayed in production until very recently. In 1882 it was bought by the Mayer family. Chribska became part of the Borske Sklo National Corporation during the 1950's. Chief designer at this time was Josef Hospodka, who specialised in sculptural blown glass designs. 

The Sommerso technique was originally developed in the 1930's by Antonio Da Ross. Sommerso (Italian for "submerged") is the Murano glassmaking technique of creating two or more layers of contrasting glass without the colours mixing together. It is formed by dipping coloured glass into molten glass of a different colour, before blowing the glass into the required form.
