Things to Consider
Each handcrafted slab represents a one of a kind piece that will embody unique variations in patterns, texture and color blends.
Ribbon Glass in particular will evolve during the firing process and unexpected characteristics may within a piece.
Examples of these uncontrollable characteristics include:
Art Glass Surfacing is made to a nominal thickness of 30mm( 13/16″ ), thickness variation with each piece may be as much as +/-3mm.
Color shade variation may occur in all fired products. The proportion of the colors within each sample represented on the website and in samples you receive may vary from the final production piece. Each Ribbon and Crush panel is hand crafted and no two pieces will ever be exactly alike.
Every Art Glass Surfaces is hand-cast from scratch, therefore we need some basic size information:
- Order the finished length that is needed, (length 14′-0” or 4,267 mm). Note that slabs will be manufactured a minimum of 1” (25 mm) larger than the requested size in every dimension to allow the edges to be finished appropriately. Although large AGSurfaces are possible, the are very difficult to handle, transport, and fabricators have certain saw limitations to contend with – a more common length is 8’-0” or 2438 mm.
- Order the finished width that is needed, Width (4’-2” or 1270 mm). Note that the slabs will be manufactured with a minimum of 1” (25 mm) larger than the requested size in every dimension to allow the edges to be finished properly.
- Thickness: All AGSurfaces slabs are made to a target thickness by depositing a desired weight of glass with the expectation that it will fuse and settle to the calculated thickness. Variability is inherent with the process and the finished thickness may vary from 5 to 10%. Weight: Glass has a density of approximately 2400-2800 kg/m3 (0.09 pound/cubic inch or 156 pounds/cubic foot). For illustration purposes, a slab measuring 40” x 40” x 11/4” weighs approximately 165 lbs.
As a result of the manufacturing process every slab will have one face that has a relatively smooth glossy ﬁnish and one face that has a textured ﬁnish.
- Glossy. The glossy ﬁnish is the surface of the slab facing the heating elements (the top face). As the glass melts, it settles to a smooth shiny surface ﬁnish. Sometimes the glass surface can crystallize, causing some unevenness in the gloss. Further polishing is possible, but it must be carried out by your fabricator. A more common solution is to add a ﬂux to the unﬁred surface of the glass, creating a more even gloss but slightly weaker surface. A glossy ﬁnish is usually desirable for furniture, counter tops and partitions.
- Textured matte. The textured matte ﬁnish is the opposite side of the slab (the side in contact with the bottom of the kiln).
When requested, a rougher textured ﬁnish can be created on a Crush slab in place of the Textured matte ﬁnish. The rough textured ﬁnish is the result of granulating the glass that creates small voids between glass particles. The larger the glass granules, the rougher the ﬁnish (our standard is ¼” granule). This ﬁnish is ideal for slip-resistant ﬂooring applications.
Float glass is used to make our slabs. It is most often found in either green or blue-green shades (caused by iron oxide found in the silica deposits). We color our slabs using ceramic stains and nothing else. The final color is a result of the mixing of the natural glass color plus our stains. Naturally, some colors are easy to obtain, others like absolute white are more difficult. The variability of the source of the glass causes shade variations from slab to slab.
Crush slabs are made from recycled granulated glass that is colored and deposited in the kiln.
Note: When planning a custom color order, some colors, typically yellow, yellow-greens, red and orange are reactive colors that tend to flow and migrate when subjected to the intense heat of the Ribbon AGS manufacturing process.
Ribbon slabs are made with strips of float glass that are colored and assembled in the kiln. We offer a range of 8 standard color combinations, many other variations and combinations are possible, and custom orders are welcome.
Note: When planning a custom color order, some colors will react differently than others and may not result in a color that is not as intense as the reference chip – always request a sample.
