From Acid Etching to Zebra board
Acid Etching
A process for achieving an obscure frosted appearance, where the surface of flat or bent glass is obscured by treatment with hydrofluoric acid or its compounds. The glass surface is covered with an unreactive barrier medium such as wax, the desired design is inscribed in the barrier, and then hydrofluoric acid is applied. The acid will only corrode the areas that are not covered by barrier.
Acoustic laminate
A laminated glass with special interlayers with better "acoustic performance" than ordinary laminated glass.
Airspace
The cavity formed by the spacer bar between the two "panes" of glass in an "insulating glass unit". It is generally filled with air, hence may be also referred to as the "airspace". The air can be replaced with argon for example, or other inert gas, for enhanced thermal insulation.
Annealed glass
Annealed glass is ordinary float glass, that has not been heat-strengthened or tempered.
See moreAnnealing lehr
The section of a glass manufacturing line immediately after the glass formation, where the glass is carefully cooled to prevent any undesirable residual stress in the glass.
Anti-reflective glass
Surface-coated glass, which minimises light reflectance and appears therefore to show virtually no visual reflection.
Arrisseding
A basic form of edge working involving the removal of sharp edges of cut panes of glass by means of abrasive belts, resulting in a coarse ground finish. A standard arriss is often applied to annealed glass prior to being heat treated.
Asymmetrical glazing unit
A sealed unit that consists of panes of glass of dissimilar thickness.
Autoclave
A large pressure vessel that Polyvinylbutyral "PVB" laminated glass is heated in and subjected to high pressure, to bond the layers of glass and PVB together.
Balustrade
A term commonly used for a "barrier" or form of "guarding", generally waist-height, which protects people from falling where there is a change in floor level, for example stairs and balconies.
