What is slumping?
Slumping is a kiln forming process that uses heat and gravity to transform sheet glass into the shape of a mold. We can to create an almost endless variety of forms when slumping glass.
When the glass is heated in a kiln and enters a liquid state, the force of gravity pulls it to the floor. In glass slumping, this “floor” is some type of mold.
After the heated glass has flowed into the mold and assumed its shape, it is cooled back down to room temperature with an appropriate annealing phase. By the time the glass is fully returned to room temperature the liquid glass will be crystallized into the rigid form of glass with which we are most familiar. Its new permanent shape will be that of the mold.
Simply put slumping is a technique in which items are made in a kiln by means of shaping glass over molds at high temperatures. This means we can manipulate patterns and textures to customise glass for you!
Due to the handmade nature of Escape slumped glass in some cases patterns, on a larger scale may very slightly from samples provided. Care should be taken when selecting textures as images may not overlap from panel to panel. The molding process may cause random variations in background textures and some expansion, contraction or toughening markings may be evident in the final product.
Slumped glass has two texturally different sides each with corresponding optical differences. It is generally preferred to view the glass from the smooth side.
All Escape slumped glass is produced with fired edges, additional edge work is not necessary.
What are the specifications of the glass?
Escape Glass is available in 6, 8, 10, 2, 16 and 19mm thick clear float glass. Colour tinted glass is available in green, blue, bronze, grey and super grey (subject to availability). Glass can be colour coated in opaque and metallic paint or sandblasted. Maximum panel size for 6 and 8mm is 2600x1500mm for 10 and 12mm it is 2800x1600mm. Depth of some patterns
Can I add my logo?
Of course you can, talk to us today on the various ways of making this happen and how it can be done.
What patterns does your glass come in? GLASS PATTERNS can be viewed here.
Can you make glass in any shape?
Standard or counter sunk holes, radius's, corners, curves and special cutouts are available. The diameter of the circular holes should not be less than the thickness of the glass and the total area of the holes should no exceed 10% of the area of the panel.
The glass has a nominal flatness, however where necessary a flatter glazing border (generally 10 to 40mm wide) is provided to ensure ease of installation.
Escape Glass requires finished glass sizes for all panels. All panels manufactured to a tolerance of plus or minus 3mm from quoted sizes. Templates must be provided for all non standard custom shapes and must be clearly marked with hole diameters, cutouts etc. We reserve the right to judge each job on an individual basis
What is toughening?
Where human impact is a possibility or local bodies require it our glass can be toughened to comply with all local building regulations. All processing must be done before the glass is toughened, any attempt to cut, drill or edge work the toughened glass will result in damage.
All slumped glass conforms to New Zealand and Australian safety standard ANSIZ97 UA when toughened and should be installed in accordance with ANSIZ97 AU safety standards. Setting blocks and spaces must be used at all times. When toughened, slumped glass increases in tensile strength 4-5 fold and takes on the same safe breakage characteristics of toughened flat glass breaking into small relatively harmless fragments. Toughened glass has the same sound installation properties as annealed glass. Normal weathering or exposure will not affect toughened slumped glass, however, the toughening process does not increase the resistance to scratching or abrasion.
