Public Glass, San Francisco

I took the Introduction to Hot Glass class at Public Glass today, and will never look at another glass the same again.  I made an ugly paperweight, a deformed glass, and one glass that I’m actually proud of, and may actually use for drinking one day.  I had no idea how hot glass needs to be to work with.  When it’s malleable, it has the consistency of honey, and demands that you rotate it constantly or else it turns into a lopsided blob.  Below are some photos, and oversimplified directions.  I would not try this at home, but definitely recommend trying it.

Step 1.  Dip the metal rod into the pot furnace filled with molten glass, while rotating the rod constantly.

Step 2.  Place the rod in water to cool the handle, while rotating the rod constantly.

Step 3.  Carry the rod to the next station (either the bench or marver to begin shaping, or to the glory hole to reheat).

Step 4.  To create an opening, you blow through the rod and a small air bubble forms.

Step 5.  Finally, you transfer the glass to another rod called the punty, and then create a new opening from the side where the air bubble formed.  Continue reheating, rotating and shaping, and then release.  Voila!
