I am not sure what you mean by MAPP torch.
That said, I will go on to the striking and reducing.
Some glass is striking. You get it hot, then let it cool and when you put it back in the flame, the composition of the glass causes it to develop various ways and change color. Striking red, yellow and orange is almost clear, light amber, but as you work it and it gets hot and cool it will develop the red/orange/yellow for example. The Double Helix striking glass is not easy to use with a torch that does not have oxygen added to the flame.

Reducing is when you make you bead, let it cool some, then put it into a flame that has more propane/less oxygen than a neutral flame. On the Hothead, you can carefully cover the oxygen holes around the torch to get the reducing flame. When you waft the bead in that flame, the surface gets some shine/iridescence.

Garaging is when you keep your kiln on as you put the beads in it, holding a temperature until you are ready to move on to an anneal.
