Effetre is glass made on the island of Murano, Venice, Italy. And is very popular with lampworkers partly due to the vast array of colours available.

Many stockists of Effetre glass rods use their own colour descriptions and stock numbers. The last 3 digits used by any stockist for their stock numbers will refer to the Effetre factory stock number.
