Process: Aerial or offhand
glassblowing is an advanced form that involves shaping glass without the use of
a blowpipe or punty. Glassblowers manipulate the glass directly with hand
tools, using centrifugal force to aid in shaping and forming the glass.
Use: This technique is employed
when artists require precise control and detailed shaping, especially in
creating intricate glass art pieces. It is common in sculptural glass work.
Observations: The glassblower
observes the glass's response to the tools and their movements. They pay
attention to the glass's heat and viscosity, adjusting their actions
accordingly.
Cognitive Processes: Glassblowers
rely on their experience and skills to control the glass's shape and movement.
They must make real-time decisions based on the glass's behaviour and their
artistic vision.
Perceptual Stimuli: Visual
stimuli play a crucial role in this technique as glassblowers observe the
glass's response to their tools and movements. The tactile feedback from
handling the tools and the heated glass is also important.
