Accuracy in Glass Engraving: Preparation and Alignment
Engraved glass relies on preparation carried out before any cutting begins.
Linework, spacing and placement are resolved at the artwork stage, then checked again during stencil application to ensure the design will sit correctly on the surface.
Stencil and Alignment
Artwork is first prepared and printed onto film, which is used to assess scale and positioning on the glass.
This allows the design to be checked against curvature and proportion before engraving. Adjustments are made at this stage, rather than once the process has begun.
Application
The prepared film is aligned to the glass by hand.
Positioning is set against a reference layout, ensuring that the design sits square and balanced across the surface. On curved forms, this step is critical, as small misalignments become more visible once engraved.
Complex Layouts
More detailed commissions require additional stages.
In one case, a wraparound whisky glass incorporating multiple molecular structures was prepared through several iterations before the stencil was finalised. The design was adjusted repeatedly to maintain clarity and spacing across the full circumference.
Engraving
Once alignment is confirmed, the stencil is applied and the glass is sandblasted.
The engraving follows the prepared layout, producing a consistent etched finish with the design cut into the surface.
Outcome
The finished piece appears straightforward, but is defined by the accuracy established during preparation and alignment.
The engraving stage follows the work already done.
