The production of this type of crystal bowl, known as Czech or Bohemian crystal, dates back a long way, with modern examples like the one shown often being vintage and produced from the 1970s onwards. History: Glassmaking in the Bohemia region (now the Czech Republic) has been documented since the 13th century, and the skill of cutting glass has developed over the centuries. Modern production: Items like this, with detailed cut patterns, are often sold as vintage pieces from the 1960s or 1970s, although traditional hand cutting continues today for luxury products. Very large bowl, hand-cut Bohemia crystal, from the 1970s.
