The same glass, by physics

The walk follows the studio. This page follows the physics. Rows are strands, columns are studio steps, and each lesson sits in every strand it teaches. Read along a row to meet one idea in every place the studio uses it. Read down a column to see everything one step depends on. 21 of 80 cells hold a lesson; the empty ones are what the site does not explain yet.

By strand

Foundation first: a lesson comes after the ones it builds on.

structure

How the atoms are joined: the network, its breaks and what fills them.

  1. 00 Glass is a liquid that stopped
  2. 01 Clear glass is not clear

flow

Viscosity and the glass transition: how a melt stiffens and what that leaves behind.

  1. 00 Glass is a liquid that stopped
  2. 01 Clear glass is not clear
  3. 02′ Some glasses are long, some short
  4. 06 Glass remembers how it cooled

stress

Strain frozen in by cooling, and how polarized light shows it.

  1. 06 Glass remembers how it cooled

absorption

Light taken out by ions, particles and band gaps, compounding with path length.

  1. 01 Clear glass is not clear
  2. 02 The furnace air picks the color
  3. 03 Each ion absorbs its own bands
  4. 04 At heat, glass gives back what it takes
  5. 05 Some colors must be struck
  6. 08 Every color on the shelf

emission

Light given back: thermal glow and fluorescence.

  1. 04 At heat, glass gives back what it takes
  2. 09 One glass gives light back

light at surfaces

Refraction, dispersion and interference: color with nothing absorbed.

  1. 07 Color with no colorant
  2. 01 Clear glass is not clear
  3. 06 Glass remembers how it cooled
  4. 07′ Clear glass holds every color

seeing

A color is a spectrum through a lamp and an eye.

  1. 08 Every color on the shelf
  2. 09 One glass gives light back
  3. 09′ Color is a fact about an eye

over time

What water and years do to a glass.

  1. 01 Clear glass is not clear
