First of all, pinch harmonics are sounded with by catching the string with the edge of your thumb or any other finger you'd prefer right after you pick the note, and moving your pick around will give you different pitches of pinch harmonics, you probably already knew that.
Artificial harmonics on the other hand are also sounded on fretted strings(maybe this is where the confusion comes from) but are created the way natural harmonics are. They are usually sounded one octave higher than they are fretted (12 frets up)
What all this entails is that to sound an artificial harmonic of G on the 6th string, I would fret the G at the third fret, then lightly touch the string with my index finger 12 frets up, and pluck the string with my thumb, then quickly take my hand away to let the harmonic sound clearly.
There. I stil dont know how anyone could get those two confused.:confused:
