Durobor
Durobor was one of the first companies to mechanically produce glass in the 1930s. In the 70s, they followed up with an automatic solution for producing glasses with a heavy bottom containing the characteristic bubble. In 1985, a guiness book entry for the biggest glass pyramid created a lovely side anecdote. Today, the company's name equally stands for renowned quality and innovative design; this shows in exciting, seasonally released products.
