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.
