MOLTEN GLASS VS Prince Rupert's Drop - Smarter Every Day 285

Summary by Krater

Destin from Smarter Every Day visits Cal Breed at Orbix Hot Glass to explore the material science of glass and how to cast a Prince Rupert's drop inside molten glass and shatter it.

From the video

Answers: Can you cast a Prince Rupert's drop in molten glass and shatter it?

• Prince Rupert's drops
• glassblowing
• material science
• viscosity vs temperature of glass
• phase transition of water vs glass
• annealing glass
• high-speed photography of glass fracture

What it concludes

• Glass is a second-order transition material where viscosity changes gradually over a wide temperature band.
• Blowing air into molten glass using the ideal gas law allows glass artists to form shapes.
• Failure in glass can be used as a space for discovery and artistic design when carefully managed with annealing.
• The Prince Rupert's drop can be successfully embedded and cast inside a block of molten glass without premature shattering.
