The history of Nový Bor in North Bohemia- is indelibly linked with the art of glass-making. The tradition of glass making in the region goes back more than seven hundred years. Thanks to abundant stocks of wood –used as both fuel and raw material -and crushed quartz used in the melting of glass, the region provided ideal conditions for the craft. Glassworks in different areas date back to medieval times and have been traced due to various archaeological finds –such as small pieces of melted glass and fragments of moulds -in places where old glassworks used to stand.
