Blow and cap

I never got the blow and cap method to work for me. My blow hose works well . What’s the secrete of the blow and cap?

Practice. You want a good amount of pressure in the pipe and your thumb ready to go. Try it on a cold plugged pipe, if you hear air move when you take your thumb away you did it right.

I would think that doing that with a hose was going to really require a good deal more pressure than just doing it with a blowpipe. Is that bad thinking?

You cant exactly do it with the hose. Blow, cap, bubble, then hose.

I've never met Nikolaj Christensen, but I like his explanation.

Have the bottom part of you thumb pad resting on the mouthpiece almost covering the opening completely, so that you can easily seal it off, and then place the mouthpiece and positioned thumb in your mouth from the side. Blow and seal off the pipe while you are blowing. Should look sort of like you are playing a flute but with a thumb in you mouth also. As Shawn said practice on a clogged pipe by getting it hot and try capping. Hold it up to your ear and uncap it and if you hear a pop you had it sealed. When you start capping with molten glass it does not take a lot of pressure, the heat will do the work for you. If you are blowing bottle glass, which if I remember you are, it will take a bit more pressure for the capping puff. But heat does wonders.

When I learned I found it helpful to excessively overdue the amount of air being blown before capping.

Practice on a clogged pipe. Release the air near your ear to know if you got it right. The more you practice the easier it gets.
