Guys you're barking up the wrong tree here. Seeing red glow is not any useful indicator, and in fact usually becomes impossible to do in less than a gram. Ignore it, it's leading you astray.
Follow the guidelines instead, they'll get you going like the hundreds of other owners before you. Then you can experiment with modifications.
From clean, load .2 grams or a bit more perhaps. Melt it well in with short power pulses before you attempt to draw vapor. Keep it cooler until it's fully melted in. Then key it on, let it heat, about 10 seconds or so and try a test puff, if it's good, go for it. If not give it another five or so and try again. Using a fresh battery, of course.
Expect at least a few good hits before it starts to taper off as the reservoir goes down some. When it slows up, add .05 to .1, never more. Expect at least half a dozen full hits from it but not a huge number it's at tiny bit of oil after all.
You can't just bung some in and hit the switch and expect good results. Nor will you get them watching glowing. Rather concentrate on the load inside, battery condition and heat going on. You'll pick it up quick enough, but you have to use it as designed. The idea is to use the heater to heat the ceramic with the goods already absorbed inside. Like microwaving a damp sponge, vapor is supposed to be generated in the bulk of the material, not on the surface.
Too much material will make it slow and 'muddy' and invite leaks, too little (or not properly soaked in) will give thin vapor and burnt taste (sort of what's happening?). If in doubt, error a bit on the too much side, you can vape it back down.
If the ceramic looks dry, it probably is (some concentrates can fool you here). Always question your battery condition if it slows up, if in doubt swap batteries first. Putting more into the unit when the battery is the problem will only add flooding to your troubles.
That routine is proven to work at least OK for all of us. Lots of others don't.
Best wishes
