DRAENERT opens up for the manufacture of glass tables the endless universe of colours by a new technology. With
special glass lacquers, we combine the brilliance and clarity of glass with almost every required colour shade; also
mirror glass is possible. To best preserve the colourfastness of the lacquers we use for this product line, exclusively,
white glass as a carrier material, a clear glass with low iron oxide content, which excels by a clearly fainter tinge of
green. In addition, a special adhesive technology enables, in connection with the glass lacquers, a continuous vision
on the glass surface without interruption by glued-on metal parts. They, therefore, stay invisible.
Float glass is an industrial product and is manufactured fully automatically in huge production lines (about 1.2 km
long), at a melting temperature of about 1600° C. Similar to the steel worker’s blast furnace, a glass furnace is designed
to have a useful life of about 10-11 years in which tons of flat glass sheets roll off the conveyor belt around
the clock, day in day out. They are picked, loaded and transported to the glass processing industry by road, rail and
sea. Here, they are cut to size and the edges are processed. It is only at this stage that they arrive at our workshops
for use in our production.
The quality requirements in terms of bending tensile strength (brittleness, breaking strength), transparency
(blisters, inclusions, opacity), surface quality (scratches, streaks) and glass colour (green cast, white glass) are laid
down in regulations for DIN and Euro-standards. Apart from technical feasibility, the tolerances here are mainly
influenced by the needs of key customers. Basically, it is impossible to manufacture glass completely free of blisters,
inclusions or opacity. Limits are set by the consistency of the natural material, which is neither perfectly pure nor perfectly
constant, and the highly complex melting process. Defects which are outside tolerances are identified and marked
on the production line by photo-laser sensors so that they can be isolated and rejected during cutting. Fine, hairline
scratches, small enclosed blisters, fine opacity or inclusions are all within these tolerances as long as their effect is
not too disturbing in normal light from a distance of 1.5 m.
General care instructions
There is not much to be said about the care of float glass. Float glass is both a user-friendly as well as a sensitive product,
resistant to virtually all normal household acids and alkalis and easy to take care of with conventional non-abrasive
cleaning agents. This is valid also for lacquered surfaces. As part of our range of care products, DRAENERT offers
a special citrus glass cleaning spray. Dull rings on the surface of the glass mostly come from lime deposits in water
and can be easily removed with a non-abrasive de-scaling agent. However, glass can be easily scratched through
mechanical influences or even break as a result of mishandling.
A few basic principles in handling glass furniture:
- Glass tables have a similar load-bearing capacity as comparable tables of a different construction, but should
not carry more weight than for normal purposes.
- Please never use glass tables as a seat.
- Glass tables are not a children’s toy.
- Glass should never be subjected to extreme temperature changes (e.g. a hot pan or deep frozen items). This
could lead to spontaneous breakage. Please use mats.
- Take care with ceramic, porcelain or diamond rings, their extremely hard edges could easily cause scratches.
Please use mats.
- Damage to edges can result in a broken plate, sometimes with a time delay.
- As the bottom plates of some models could easily be scratched on stone or ceramic floors, PVC slide pads
should be used (available on request).
