Crackle Glass Egg

12. Water is applied to the jack line, the pipe is tapped and the glass breaks free of the blowpipe.

13. The blowpipe is put into a metal bucket to cool and the egg is re-heated.

14. When soft enough, pliers are then used to pull out the neck to thin it, it is jacked to the proper size, re-heated, jacked again to make the opening about 1/8-inch inside.

15. Water is applied to the jack line and the excess glass is lightly tapped off into a bucket.

16. After the next two re-heats, use a needle valve on the air hose to puff-up the end of the crackle glass egg.

17. There is one final re-heat, and the crackle glass egg is then tapped off into the annealing oven at 900-degrees where it will slowly cool for 12-16 hours.
