Process: Incalmo is a technique
used to create pieces with contrasting colours by joining two or more separately
blown glass bubbles. These bubbles are heated and fused together to create
distinct sections with different colors or patterns.
Use: Incalmo is commonly employed
to create glass vessels or sculptures with visually striking colour contrasts
and patterns. It allows glassblowers to combine variours colour combinations
within a single piece.
Observations: Glassblowers
observe the temperature and alignment of the separate glass bubbles as they are
joined. The success of incalmo relies on precise heat control and accurate
alignment.
Cognitive Processes: Glassblowers
need to plan the colour combinations and pattern arrangements in advance. They
make real-time judgments about the temperature and alignment of the bubbles to
ensure a seamless fusion.
Perceptual Stimuli: Visual
stimuli are crucial as glassblowers monitor the colours, patterns, and alignment
of the glass bubbles. Tactile feedback is also important, as they manipulate
and join the heated glass sections.
