OUR Clear glass

aesthetically pleasing, smooth and homogeneous

Glass is a product of nature. The most important raw materials are quartz sand, chalk and soda. Glass is produced by bonding these different substances at high temperatures and then solidifying the melted mass again during cooling, without the 
occurrence of crystallisation. The untreated, hard surface exhibits impressive qualities of chemical resistance, imperviousness to spots, simple cleaning and is absolutely hygienic – not to mention its aesthetic aspects.

Product description coloured glass Optiwhite (white glass) TSW

Our glass is made by float glass technology and is in accordance with generally accepted EU standards. There are two surface options: glossy or matted (satinized). Optiwhite glass is decoloured by exactly dosed metal salts and is largely free of green casts occurring in the glass.

Irisation appearances such as light clouds, little spot, rings, flow marks or drawing defects in spectral colours are subject to physical effects in polarized light and cannot be avoided. Small bubbles, spots, glass scatterings, flow marks, centre line flaws or ripples are acceptable material characteristics as long as safety and function are guaranteed.Such imperfections are evaluated in diffused daylight from a distance of about 0.5 m.

Depending on type and size of glass 100% pure glass is impossible as far as production is concerned. Glass is particularly amenable to scratches (no subjects with sharp edges must be placed on it, for instance). Water and other  liquids must be removed from the glass surface immediately as limescale lips might develop. Also, no deep-frozen or hot objects should be placed directly on the glass surface as this may cause damage in the glass. Exposure to light and other lighting causes different colour effects that change depending on the angle we look at the glass. This is a characteristic which is typical for this material and cannot be complained about.

Our glass is suitable for winter gardens with an ambient temperature between +5° and +30° Celsius. Both cold and thermal shocks have to be avoided as such abrupt variations in temperature might cause the glass to break. This may be the case, for instance, then the window is opened at sub-zero temperatures and is closed again after some time. It is also important to keep a minimum distance of 40 - 50 cm from radiators. 


If you have chosen a high quality glass table, in order to maintain your table’s perfect surface well into the future, it is necessary to observe the following advice:

  • Immediately wipe off all liquids that come into contact with the tabletop in order to prevent the formation of chalk spots.
  • Grease spots can be rubbed away using hot, distilled water and a cotton cloth.
  • The smooth side can be cleaned using glass cleaner or a micro-fibre cloth.


Due to the sophisticated and complex production process, deviations in mass and minor colour differences are to be expected. The tiniest of bubbles, little stones and streaks in the glass are unavoidable with today’s current state of technology. Glass is not scratchproof. We therefore recommend handling it with care during day-to-day use. We also recommend placing a protective pad underneath objects you place on the table.

Evaluation criteria and guidelines for visual inspection of furniture are defined by the "Deutsche Gütegemeinschaft", quality mark RAL-GZ 430, defined and specified as follows:

  • Evaluation basis: Emmetropic eyes; diffused daylight (no direct sunlight or artificial light).
  • Evaluation of harmonic overall impression: From a distance of  2 - 3 metres.
  • Evaluation of details: From a distance of about 0.5 metres.
