Extra thick silver leaf is used exclusively for artistic work on glass (of which Murano is its maximum expression). Its extra thickness prevents the leaffrom breaking up (or almost disappearing) in very high temperatures, frequently over 800°C. Extra thick silver leaf is not suitable for other working techniques. Extra thick silver leaf is packaged into books of 25 leaves each.
Resistant to very high temperatures, the high thickness pure silver leaf is used for artistic decorations on glass. Each book contains 25 leaves.
