Before I went on the trip across the state to visit glass making facilities, we had been learning about the art of fusing glass. I would like to pick up now where we left off.
You watched a video about the process of fusing glass so that it forms a new piece that is flat. Now I want to introduce you to how fused glass can be formed into vessels. This is done through a process called slumping. You begin by fusing a piece of glass in the kiln. Then you place it over a mold and put it back in the kiln. The heat will cause the glass to bend to the shape of the mold.
Watch the following video and answer the questions below. This video not only shows you how slumping occurs but also shows you how certain types of glass can have reactions when they are heated while touching each other. It also shows you how to use stringer to create a linear design.

Answer these questions in your journal:
1. What tools were needed for using the stringers?
2. Why did the stringer not change colors in some places?
3. There were two different firing schedules in this video: one for fusing and one for slumping. What are the differences in the temperatures for these two processes?
