The range of art glass supplies required for kiln forming need not be extensive. General fusing projects can be produced with a minimum of supplies.
It is not necessary to have a large store of supplies to produce great fused designs.
Glass fusing can be as simple or as complex as you want to be.
With a glass kiln, cutter, glass pliers, thinfire paper or kiln wash, great results can be obtained.
As you become more experienced you can add to these basic supplies so as to expand the range of glass art you wish to produce.
For many years I have purchased my supplies from Delphi and have found them to be a very reliable and helpful supplier.
