Depending on the project and customer requirements, the front side, back side, or both sides of the panel may be treated using various techniques to achieve diverse 3D textures. As a result, the glass does not have to remain purely flat or curved (maximum bending angle 120°), but may feature surfaces reminiscent of rippling water, hewn stone, or wood grain.

The base variant is flat material with nominal dimensions of 700x700 mm (for a surcharge, the dimnesions can be increased to 1000x1000 mm), that we can subject to a fusing process to bend (curve) the glass according to customer requirements. The maximum angle of curvature is 120°.

‍

Notice: The choice of colour determines the maximum size of the panels. Colours containing Triplex Opal (white) can be produced up to a maximum size of 800 × 800 mm. Panels measuring 1000 × 1000 mm are available only in smoke colours combined with crystal.

The weight of the standard 700x700 mm format is approximately 13 kg. Panels in the maximum possible dimensions (surcharge) weigh approximately 17.5 kg.

‍

Due to the manufacturing process, it is not possible to achieve precisely the same thickness across the entire panel. Thickness varies between 7–10 mm. We can custom manufacture panels with a maximum thickness of 30 mm. Thicknesses other than the standard 7–10 mm will incur a surcharge. The material has a maximum allowable variance of 2 mm.

‍

Notice: As material thickness increases, not only do optical properties change – such as transparency, light transmission, and light absorption – but the distinctive texture of the glass may also be visually suppressed. This effect is particularly pronounced in smoke colours with a crystal admixture and may be further intensified by the use of an unsuitable black backing or coating. These factors must be carefully considered prior to placing an order. Subsequent claims based on these characteristics will not be accepted.

The texture varies from one piece to the next and depends on many factors, such as the fractions of the glass fragments, their orientation, dispersion, etc. BG is a special material, and each piece is a unique original. For a surcharge, customers can request a more compact texture in the material achieved by aligning the glass fragments in the piece. ‍

‍

Notice: Depending on the selected material thickness, optical properties such as transparency, transmission, and light absorption may change, as may the visibility of the glass’s unique texture and internal structure. This applies especially to smoke glass with a crystal admixture and may be accentuated by the use of an inappropriate black backing or coating. These factors must be carefully considered prior to placing an order. Subsequent claims based on these characteristics will not be accepted.

The selection of colour options is based on the standard production of Janštejn Glassworks. Currently, there are 14 colours: 1 Triplex Opal BROKISGLASS, 2 smoke colours in combination with crystal (Smoke Grey Triplex Opal BROKISGLASS and Smoke Brown Triplex Opal BROKISGLASS), and 11 colours in combination with Triplex Opal (white).

In the case of Light Pink Triplex Opal BROKISGLASS, the glass may display subtle tones of brown as a result of a slower onset of colour.

For a surcharge, multiple colours can be combined within a single panel according to customer requirements.

Depends on use. Gloss and matte options are available.

Due to the nature of the material and manufacturing processes, the back side is not 100% flat.

In the base variant, the back of the panels is sandblasted, leaving a matte finish. For a gloss finish and for safety reasons, a coating can be applied that acts as a safety film. The safety coating is applied to base variant panels above the standard size of 700 x 700 mm. In custom dimensions (up to 1000 mm), there is a visible joint on the back of the panel, but this has no negative effect on the properties of the material.

‍

In the base variant, the edges are chamfered by hand, therefore the same angle cannot be declared along the entire length of the piece. The process softens the sharp edges left behind by the waterjet cutting process. The resulting appearance of the edges is matte as opposed to a polished finish.

Limitation: holes cut in panel cannot be chamfered.

Holes with a minimum diameter of 100 mm can be polished.

Curved edges can be polished only when the curvature is 80°–100°.

The edges on panels larger than the standard 700 mm cannot be mechanically polished. A glossy appearance is achieved by applying a transparent safety coating.

For both a glossy appearance (alternatively achievable with a standard transparent lacquer) and safety reasons, a transparent safety coating may be applied. This coating functions similarly to a safety film, helping to keep the glass intact in the event of breakage. The coating may be applied to the front side, back side, or both sides. For panel formats exceeding the standard size of 700 × 700 mm, a rear transparent safety coating is applied automatically. In special cases, a white version of the safety coating is also available.

‍

Notice: Application of the safety coating to the front side is not recommended for glass intended for use as tabletops, for instance. The safety coating does not protect against mechanical damage, such as scratching.

Upon request, the rear side of the panels may be treated with a diffusion coating that improves light dispersion and enhances luminous performance when the panels are backlit, while also preventing visibility of the substrate behind the glass. The coating is available in white and black and can be combined with a transparent safety coating; a white safety coating is also available separately.

Notice: The diffusion coating (regardless of colour) is not suitable for backlit smoke glass. In such cases, an individual, project-specific solution is required, and we will be happy to advise you.
