If you're looking for some standard terms for the parts of a pen, I have a modest proposal based on what the parts were generally called in the golden age of dip pens.
https://thesteelpen.com/2017/10/14/defining-terms/I do use the flame method myself, but the trick is to flame only the middle of the nib for about 1.5 seconds (a long one-second), take the flame away, and then do it once more for a delicate nib, maybe one more time for a larger nib, and then wipe it off with a tissue. The heat will soften the shellac (most vintage nibs used a form of shellac to protect the nib from rust, which is why alcohol can work), and then you wipe it off. If there is still pooling of the ink, or it won't stick, then try it again.
Do not put the flame directly under the tip, keep it centered on the space where the ink will go, the concave side of the center of the pen. The heat will still transfer to the delicate tip, without affecting the temper (it has to get pretty darned hot to really affect the temper, but this can happen at the very small and delicate tip)
Also, if you flame, make sure you put the nib into a holder. You don't want to be holding it in your fingers as you heat it up.
I have captured some of my thoughts on this sometimes contentious topic. (including why I never use the saliva method)
