Stack

Sometimes stacks, when full fused, melt down to some visually interesting shapes and colors.  It is  surprising to me that each color in the stack retains a distinct separation from it's neighbors in the final puddle.   The mobility seems to depend on the laws of 1/4 inch and gravity.  Take a look at the tilt of the French vanilla, transparent and and white/salmon streaky in the left hand corner of the fire paper in the picture below, then watch for the end result.

Below is the stack from a bird's eye view.  Notice that the squares in eight of the nine layers are staggered so that the final shape is less likely to be square.

The only piece of glass that is a different thickness is the white/salmon opal on the top - it is only a small piece and is turned on it's side.  Looking at it from the top, you can actually see the layers in the glass that categorize it as a "streaky" sheet.

Just the slightest off center placement of the white/salmon opal is enough to pull the entire stack the direction of the "lean" when the temperature rises.  Check out the final piece below and the flow of the tilt is apparent.

If you look carefully, you can actually count each of the nine layers in the final piece, however.  Even though they worked to achieve the 1/4 inch thickness, the integrity  of each layer in the stack is discernible.

I would like to try another stack or two until I get one that does not tilt to one side, but creates concentric shapes, rippling from the middle - at least that is my expectation.
