We use drop moulds quite often to do tests, demonstrations, and also
to produce pieces for sale.
For our purpose 5mm fibre board performs fine; it is easy to cut and
can be used serveral times. We use insulation bricks to build up
support for the fibre board.
Depending on design we sandwich strips or pieces of HiGlass GIN (coloured
art glass series fusible with clear float) between layers of clear float
(window glass). HiGlass GIN softens earlier than float, which
allows interesting effects. You will need some experimentation
to find the optimum heating profile to achive a good fusion together
with the correct sagging of your glass. This very much depends on your
kiln and heat distribution.
Hope this help; please email if you need more details.
