2 x Sheets of 1/8" Bullseye Fibre Paper This Bullseye fibre paper is approx 3.2mm thick. You will receive 2 pieces, each piece is 15cm x 30cm. It can be used as a shelf separator and helps prevent bubbles between the shelf and the glass while providing a smooth base for your work. It can be used as a dam and insulates against thermal shock and improves annealing. It can also be used for creating bas-relief texture and design in your work, simply cut to shape and place under your glass before fusing. Ideal also for creating jewellery - cut into thin strips and place between two pieces of glass to create preformed holes that run through your glass.
