I think the blue vapor may have something to do with size of the particles of water, lower temp oils and small air diluting it. I was watching a commercial where a lady was using a pressure cooker and I noticed that the steam coming directly out the hole of the pressure cooker was BLUE and not a little blue but HIGHLY blue but as the steam went a way from hole it became bigger and white.
I assume this was because the steam only became diluted with air very little in the first release of it but as it keeps going more air comes into contact with it and expands it and turns it white like like eggs whites which are clear and turn white when beat and air is introduced into it and turns to whip cream.
In the case of bud there will always be some water in it unless dry to a powder and this may be the main reason for the light blue vapor. The bud has more cells that can hold water than the oils we want so I think water may have something to do with the light blue vapor being released at low temperatures and the more moisture you have to an extent the more blue vapor you will have along with the lower temperature oils.
Also the size of the water vapor particles along with the lower temperature oils may be smaller than higher temp chemicals so blue light can reflect off of them better than bigger particle chemicals. This may be why you can get a blue vapor off of good fresh water hash because it will have a lot of lower temp oils being released before being burned by the flame and the small particles give a blue hue when seen in the light most notably the sunlight.
Here's an article about this:
http://indianapublicmedia.org/amomentofscience/why-cigarette-smoke-is-blue-or-white/
"When someone is smoking a cigarette, aside from the hacking and coughing, have you ever noticed that the smoke curling off the tip of the cigarette is blue, but when the smoke is exhaled it's white? We know that some nasty things are happening to the lungs, but why does the smoke change color?
The smoke changes color because the size of the smoke particles changes. The smoke particles rising from the cigarette tip are very small, smaller than the wavelengths of visible light. Because the particles are so tiny, when most light waves strike one of them they are not reflected back like a bouncing ball, but only slightly deflected from their paths. This is called "scattering."
The various colors of light have different wave lengths, and the ones toward the blue end of the color spectrum are the shortest. So, the short, blue waves are scattered about more by the tiny smoke particles because they are closer to the same size. Since mostly blue waves are scattered about the area, we see the smoke as blue. Most of the other, longer wavelengths go almost straight past the particles and we don't see most of them.
Smoke particles that are sucked into the lungs are a bit bigger because they are not burned down completely. Many of them will remain in the lungs, hidden from the world until the biopsy. Many are exhaled, though, and when they come out they have changed again. While in the lungs, and on the way out, they pick up moisture so they become bigger still.
The particles are now big enough to reflect all wavelengths of light equally. When all the wavelengths are reflected back they make white light, and so the smoke looks white."
& edit * if the heat is still a problem perhaps a few holes preforated @ top of cloud to help vent excess heat & may b a silicone ring atop so glass piece rest comfortably with cushion in between eh? yes vapemon or hooever lets jet get a purdy stonmon green blu turquise ozone purple perhaps thcx one wuv
sounds cool!
