At first, he works the glass only by skilfully rotating
the pipe. As additional layers are added, each drawn
from a different furnace, he begins blowing into
the pipe as well, inflating the glass into a so-called
parison. This process is repeated up to three times
depending on the size and colour of the final
product. The first and last layers of molten glass
are always crystal.
The creation of a single BROKIS light requires three
to five skilled artisans – two gathers,
two blowers, and a tender – who work together
as a coordinated and independent production team
called a shop.
To achieve its final form, the softened glass is
placed in a mould and blown into shape. At Janštejn
Glassworks, three types of moulds are used:
traditional beech wood, ideal for prototypes
due to its short lifespan; in-house crafted graphite
moulds, perfect for small series of up to 1,000 pieces
with a maximum diameter of 40 cm;
and durable Italian cast-iron moulds, used
for large-scale production.
