The process of glass blowing reminds me of life. We are molded by events around us and difficulties often bring out the best and richest of our personalities and capabilities.
Heat again (to about 2000 degrees F) with chips, pinch colors to blend. Heat and roll to blend colors.
Blow into tube, heat again to about 1600 degrees F, and then cool using a damp wooden shaper.
Repeat twice as diameter of mug grows. Temperature remains around 1600 to 1900 degrees F.
Continue shaping using heat, air, and tools.
(I love the way the colors change dependent on process and temperature.)
Prepare to switch ends from which you are working. Blowing is complete at this point. The rest of the work is all molding and finishing.
Attach the handle, heat, shape handle, and repeat the process.
Set in the the “cooling” oven, initially set at 700 degrees F for annealing. Cools overnight.
(All language is my own and paraphrasing/simplifying the process in the extreme.)
