The raw material that we use mostly in our production is optical
crystal: high quality glass with an excellent transparency,
environmentally friendly.
Hand production is a long labour-intensive procedure. Heated in
the furnace, the clear or full-color raw material melts and turns into
a viscous fluid. Then it is moulded under pressure in a metal mould. A
semi-finished piece with the shape of the final product appears. Then
it cools and hardens.
Now the product is cut by the master craftsman’s hand. In many
different steps, the facets and the edges will be cut until the
incoming light separates into the spectral colors. Polishing adds the
final brilliance.
On request, the finished crystal is coated
with metal-oxides under vaccuum to achieve a coating color. At each
production step, the quality is controlled. Finally, every single
crystal is critically inspected. The products, quite often pinned
together, are carefully packed and shipped to the customer.
