Variables in the Experiments

I finally had an empty kiln available to do experiments over the weekend! I wanted to control all the variables and see the effects of changing the temperature the glass melts thru the screen...

3 major things seem to effect the melts: time, temp and quantity.

So I kept the quantity of glass the same and the time it was held at the melting temp was also kept constant. What I changed was the temperature. This caused all sorts of variations: the roundness of the shape, the amount of bubbles in the melt, the patterns of color in the clear glass and the thickness of the finished piece.

The experiments continue... I just thought I'd share what came out of the kiln this weekend...

1700 degrees F

I like the shape of the first one, but the colors in the second. Good luck with more experiments.
