The company GLASSTAR Nenačovice was founded in the year 1996 as small family
Glass Work.
The concept of the factory is the small-scale production of art glass (the factory does not produce glass for the wholesale market) with the intention of direct sale of unique pieces in an own showroom. A few specialized crystal shops in the centre of Prague buy our products regularly and we export part of the production to several countries. The rest of our goods is sold in our shop at the factory side. At present, the factory produces about 200 different articles, e.g.: various coloured hand made decorative glass items, various animal figures blown or hand made, coloured glass fruits and vegetables, toffees and sweets, vases blown or stretched, fruit trays, dishes and bowls, ashtrays, baskets, candlesticks, bells, coloured goblets and cups, paperweights, pyramids and hexahedrons, various flowers 40 cm, 50 cm long and even longer ones and many others.
The factory
produces on a continuous process 7 days a week. The furnace is heated by propane-butane
gas. It has three different chambers and there are ceramic containers inside
each chamber where three types of raw glass are melted (pure glass, green glass
and blue glass). During the day, the raw glass is melted at a constant temperature
of 1200°C and during the night the furnace keeps a temperature of 1350°C in
order to prepare the melting for the following day. We
melt only raw materials like glass granule
and sintered glass because of ecology. Solid glass is never used as a raw material.
The molten glass is a first-rate lithium-barium crystal. Other colours are obtained
by mingling pure crystal
with different coloured powders and frits specially made for this purpose. To
obtain the final shape of each object, the process should undergo either blowing
or giving shape by hand or with the use of a mould. When shaped, each object
should get cooled down so that the tension inside the mass of the glass is diminished
to reduce the risk of cracking. This cooling process is done in a computerized
furnace at the temperature of 500° C during a certain period of the time and
then all the objects are cooled down further at room temperature till the following
day. After cooling process, each and every item passes through a strict quality
control and thus articles like fish, flowers, etc. are finished. The other,
like vases, paperweights, goblets, pyramids, etc., undergo hand-cut, refinement
and polishing processes. Complete articles are then thoroughly washed, dried
and packed in boxes. Thus our products are ready to be sold in the factory showroom
or to be sent directly to our clients.
