A mounted marver gives you the flexibility to shape your glass without holding a tool in your hand. They have a small lip designed to hold millefiori or small items (eg cubic zirconias, metals etc) you want to warm up before adding to the glass. We have 3 styles of mounted Marvers: for a Hot head, Specialised and for Nortel Minor and Mega torches. The graphite area of the Marver for a Hot Head (from Griffins Tools) is 5x 7.6cm. The graphite area of the Marver for the Nortel Minor & Mega Torches are 5.5cm x 7.7mm. It has a saddle designed to go around the top of the barrel of the torch. Note the saddles are different sizes so the Minor & Mega Torch mounted marver will not fit on a hot head. The graphite area of the Specialised marver is 6.3cm x 7.6mm. It has a steel bracket designed to attach to large barrels from 3.1cm up to 6.4m such as a Rocket, or CC torch.
