Overcoming Surface Tension
The basic idea behind kiln-pressed glass is that we can defeat the surface tension and create thin glass by squeezing it from above using weights. The basic setup looks like this:
As shown, the glass is placed between two kiln shelves and weights are placed on top. Small fiber strips placed in the corners act as spacers to prevent the glass from being pressed too thinly.
The concept is surprisingly simple but the results can be spectacular.
