Vintage French set of 6 large water cups from Biot

Really beautiful vintage french set of 6 large water cups from biot, with their characteristics bubbles. For centuries, bubbles have been well-known to glassblowers. They were their worst enemy, as they result from imperfect melting or from bad finishing. The temperature isn’t hot enough, or for long enough, to allow the gas to escape so the bubbles can pop on the surface of the molten glass. The bubbles remain trapped and create “waste glass”. At the beginning of the century, some glassblowers took advantage of the effect of this type of flaw. It was also an ancestral technique used from scandinavia to venice to bohemia for creating lamps, for example. Each of biot’s glassmakers have borrowed this technique and made it their own. Now a signature of glass made in biot, bubble glass has left its mark. This type of glasses never goes out of style and gives your table/date/celebration a touch of joy. The price is for the set of 6 cups. They are in perfect condition and each one measures 9 cm in diameter and 14 cm high.
