Once it is cooled, the Pearl is immersed in acid to eat away the copper rod, which will place the hole in the bead.
There are many techniques of beadwork to the lamp: among the most interesting and the most "Venetian", There is the technique of the sheet of gold or silver engraved, which is to form a first ball of molten glass to go pick by winding a very thin sheet of 24-karat gold or silver. The heat breaks the sheet, which gives an effect cracked, different each time.
Glass can also be covered with a second layer of clear glass to make the brightest pearls, while without this second layer, the final effect is more matte.
This lamp technology also allows to create small plates of glass in the shape of Star, heart or other rings and small animals.
Another very important technique is one which asked Millefiori Rod fragments on the main core.
Also called beads Millefiori or tile, are obtained by positioning of thin sections of wand that cover its surface completely around the soul of hot glass.
The Pearl is then heated a second time to allow the Murano from bonding with each other.
