Edging – A grinding process performed to remove the sharp, raw edge of a glass component. Edging is done for various reasons including safety of handling, protection from chipping, promotion of cleanliness, improved dimensional tolerance and mechanical function.
Bevel - Beveled glass is usually made by taking thick glass and creating an angled surface cut (bevel) around the entire periphery. Bevels act as prisms in the sunlight creating an interesting color diffraction which both highlights the glass work and provides a spectrum of colours which would ordinarily be absent in clear float glass.
Ground or Milled Edge - Refers to the processing of the entire edge (usually all edges of the part) including top, bottom, and sidewall through a CNC or mechanical operation.
Chamfer - Typically describes a uniform grind on the top and bottom of all edges with defined tolerances. Chamfers are most commonly applied with CNC grinding or other mechanical operation, though small components are “hand chamfered” on a grinding wheel.
Seam - Is usually used to describe a less critical edge treatment – often a “safety seam” or “edge break” with the primary purpose to remove sharp edges.
