The only thing that convection and conduction has to do with this is "how the herb gets heated", hot air or hot metal. We are talking boiling points, which can be controlled by pressure. My theory is the herb doesn't reach vaporization temperature every time, we just raise and lower the...

Say a container has 1500 trillion molecules in a space of one cubic millimeter at atmospheric pressure. If you remove 1200 trillion molecules from the container by suction, then you have a vacuum in the container, right? According to Pascal's Theory, pressure or the vacuum is equal throughout...

Sorry about this, you guys got me started. Bodon, what about Pascal's' Theory? It applies to vacuum also. Doc

Boden you win. I give up, it's "Magic". Give me a good theory on how it works. I just retired from a fifteen year stint in manufacturing and metalurgic field. I don't have a degree, just practical experience. I do know how to connect a fifty foot long sintering furnace to a computer so I can...

You know I have been saying all along that the reason we get so much dense vapor is because we lower the atmospheric pressure of the tip inside. The space inside the tip is so small you can easily create a vacuum with a mouth-pull or lung-pull. Which in turn lowers the boiling point of the vapor...

Someone using my name in vain? :lol: Mr. Shifter, try dipping it in coconut milk. Dry thoroughly. Doc

Try steaming. Distilled water, (no chlorine), turn temp up, hold upside down, dampen q-tip, steam away the stain. Be careful, be straight. Good luck worked for me. Doc Some people use "Magic Eraser from Mr. Clean" and scrub it.

Summer I can't say enough about magnets and Altoids tins. I still say it cuts down on the cooking of the herb between rips, yields more constant temperature. Better taste. IMHO. Doc

"Mele Kalikimaka me ka hauʻoli makahiki hou" This goes out to everyone on here. Thank you folks for helping me get by with getting old. I appreciate your kindness and camaraderie, and friendship. Doc For you without a "Funk and Wagnall", "Merry Christmas and Happy New Year"

Why do you want tungsten? It isn't very attractive, and it would cook the o'rings. You have to realize how heat sinks work. Wood does not conduct heat, so it doesn't get hot enough to retain the heat. Metal heat sinks pull the heat out of something, in order to move it to something else...

Snoutband A snoutband is someone who always interrupts a conversation to correct or contradict the person speaking. Every social group has a snoutband, who thinks they know everything. They probably don't know the meaning of this word, though. At least, not yet.

IntoTheVoid, I don't think you want a tungsten vc. After working for years with tungsten in heat sinks I wouldn't want it anywhere near my mouth. We took tungsten powder, pressed it into heat sinks, sintered it at 1000c, and machined the part. For one thing the heat conduction index for tungsten...

Twice a year we wind up repeating ourselves, trying to explain how to get the best and most from the Dynavap System to new owners of vapcaps. Like I've said before. I can tell you how I do it, but I can't tell you how to do it. You have to learn all by yourself. You keep at it and all of a...

I love the taste of different strains. I love using my sherlock. Whether using a bubbler or sherlock dry is better tasting. I call it anhydrous glass. Doc

Having trouble placing the rings where you want them? Find a soda straw that goes in the stem or body and over the condenser. Push rings where you want them landed. Build from tip to mouthpiece to get it together. Lube rings with spit or sebum. Doc

I left the Rockies to get away from snow, and damned if I didn't get up this morning and it snowed last night. Ground is too warm to stick, (thank God). I've had a Blackwood Vong Stem since they came out. Well I picked up down through buying, this piece and that piece, two Omni XL condensers...

"Hey look, everybody is out of step but Junior." Doc

Surely in all the fast food places around the world there are soda straws that will fit over the condenser and in the vc body. Just put the rings where you want with one. Doc

This bring to mind that old song,"Just trolling along". Don't you folks recognize this "Snoutband"? Look that up in your "Funk and Wagnall". Doc

kuzko, yep titanium works great in my Jarhead. I call him "Sarge". Doc
