The process
A liquid film of colloidal protein and water is applied to one glass face.

During forced evaporation a bond is created between the two dissimilar materials, the colloidal protein and the glass. When stress is applied in the form of low heat ,100 f maximum, to the dried film, the colloidal protein begins to contract. If the bond has been established correctly it proves stronger than the glass it self, causing shards of glass to be literally ripped and torn from one face of the glass surface.

The result
The result is the creation of a pattern of pristine facets that continually react to the movement of light. It's this interaction with light that separates Duncan textured, architectural glass, custom tabletops and counters, art and architectural glass from virtually all other types of textured glass.

Duncan textured glass table tops, counters, door and sidelite inserts, art and architectural glass are made by hand using our eco-friendly proprietary surface sculpting texturing process.

what is surface sculpted textured glass ?

eco-friendly glass texturing

The surface sculpting process is an eco-friendly “green” glass texturing process. The only component used is a recycled animal by-product. Any waste produced  during the texturing process is bio-degradable.

No high temperatures are used so energy consumption is almost nil compared to other types textured glass. Nor are there any chemicals used so no harmful pollutants are created that might impact the environment.
