Glassblowing a Bubble

How to blow a bubble into glass.
This video illustrates the three fundamentals of glassblowing:
1. Gathering enough glass out of the furnace.
2. Putting an even bubble into the glass.
3. Cutting a constriction (neck-line) into the bubble so it can be broken off.
Demonstration of using a blowpipe to gather glass and create a simple bubble. Also how to use the Jacks to create a constriction or neck-line in the bubble so it can be broken free of the blowpipe after it has sufficiently cooled.

Well, This looks like a job suitable for anyone that can blow up a balloon.

LOL! Love that! Actually, though, there's very little blowing involved in glass blowing. Much, much less effort required than blowing up a balloon.

So is the attachment and rubber bulb just something created to deal with COVID?

In the hell-year of 2020, you're wondering why they were wearing a mask?

@@satyr2k2 working alone in the shop and wearing a mask 😷 looks weird. Masks didn't help anyway IMHO

The masks were mandated by our employer... and to keep us safe from each other. The masks did work: we had zero in-studio transmission during the pandemic while our mask requirement was in place... and cold/flu dropped to almost zero as well.
