Metals and Glass

[Stephen Richard]

The main element in being able to combine metal and glass is size and/or thickness. as the area or thickness of the metal increases you reach a point where you crack the glass.  It would seem to me that the metal is stressed when it is only a fraction of the thickness of the glass, or a small area.  When the metal reaches a critical point – different for each metal – it becomes stronger than the glass and stresses it.
