Viscosity

What is the melting point of a solution? It hasn't got one.

Liquids are runny; solids are stiff.

10^-2 poise: liquid water

10² poise: motor oil

10³ poise: molten glass

10⁴ poise: working point (glass blowing)

10⁷ poise: softening point (glass slumping)

10¹³ poise: annealing point (glass deforms under stress)

10¹⁴ poise: strain point (glass shatters under stress)

10²⁰ poise: glass at room temperature
