1. Method for producing light dispersing and structured surfaces in an intermediate glass layer in which the surface of the base glass of a parison is roughened and coated with a second glass layer after the treatment, characterised in that the parison preformed of crystal or lead glass is sandblasted after cooling down to about 500 to 600 degrees C, whereafter a short-term reheating occurs in order subsequently to coat the roughened surface of the base glass with the second glass layer ; after finishing the forming and a further cooling down the glass object is tempered in the cooling furnace. |
