Marvering involves rolling the glass on a
marver to shape and cool it. The marver can be used to create cylindrical or
conical shapes and maintain symmetry.
Process: Marvering involves rolling the hot glass on a marver, which is a steel or
graphite table. This process cools and shapes the glass, often elongating it
into a cylindrical shape or creating a more uniform surface texture.
Use: Glassblowers use marvering to
refine and shape the glass. It aids in maintaining symmetry and can be used to
create straight, cylindrical forms.
Observations: When marvering, glassblowers should observe the
glass's temperature and texture. The marver helps cool and shape the glass.
Uniform pressure and rolling are crucial to create symmetrical forms without
cracks or irregularities.
Cognitive
Process: While
marvering, the glassblower is considering the desired shape and texture of the
glass. They make decisions about how to use the marver to achieve these
objectives and maintain symmetry in the piece.
Safety Considerations:
-
Use a marver table at a
comfortable height to avoid strain or awkward positioning.
Perceptual stimuli:
- Visual Perception: Marvering involves observing
the glass's contact with the marver and monitoring its texture and shape.
-
Tactile Perception: The glassblower feels the
resistance as the glass is rolled on the marver.
