ROCKWOOD GLASS GROUP has acquired  the first BLACK GLASS  bottle production line in China.    In operation since 2007, the factory has 2 furnaces of black glass , producing   400 000 bottles per day.     

Black glass is hard to make,  because of the reflection of the glass itself, sometimes temperatures are not even in the core of the furnace,   this phenomenon happens only on Black Glass bottles manufacturing,  this leads to uneven temperatures and results in heavy losses when the production  reaches the core .   This is one of the main reason why black glass has always been more expensive than  other standard color glass.

In the antiquity , black glass bottles were often used,  the bad quality material would result in dark glass, not always perfectly  and even black.  We can see OIGNON BLACK GLASS bottles below ,  it was perfectly accepted at the time , the black glass would protect  ingredients from the U.V. sunlight.

Black glass bottles were  found on many of the early ship wrecks along the coast of the USA .    The 1600 to 1700 the vessels would carry their alcohols in this type of OIGNON BLACK GLASS BOTTLES.  

There is very little black glass sold in the market today,   although most IRISH CREAM BRANDS use black glass,  BAILEYS,  RYANS, CAROLANS   , to protect from the UV Sunlight
