At the At the usonicig site they have a graph showing the Zip temp at around 160°C and a normal e-cig between 240°C and 320°C, closer to 320°C but not very accurate. ETA: You say you have not felt any heat but maybe it is just because the heat is lower? Who knows, maybe the mesh (I don't think...

Something tells me it isn't the plate but the heating of the pod to about 160°C every time you start a session. I wonder how much the plate is really using?

I'm sure we can but, I'm going to trust someone who has isolated that molecule and took a taste before someone who whippped up a smoothie with a plant, that has hundreds of compounds, and want's to point at chlorophyll because the plant is green. ETA: Both types of chlorophyll are nonpolar...

Just because wheat grass and spirulina are high in chlorophyll doesn't mean that it's chlorophyll that is giving them that taste. For example, the molecule that gives grapefruit it's characteristic flavor is nootkatone. It is found to only make up around 0.3 percent of the oil from grapefruit...

Actually the molecule often associated with "hay" is gamma-Valerolactone. I don't know why chlorophyll gets mentioned, it's supposed to be tasteless.

No idea what pore size might be but probably not much better than coffee filters. All they need to do is keep dry tobacco in and according to this paper being porous is a plus. I can't get them where I now live but remembering from my RYO days I would say that they would tear to easily.

My point was that you could just add the flavor, Lorann for example, to the finished juice withut adding things that you will end up trying to filter out of your extracts. Sugars are a good example because they will get through most of the filters used here (1 micron). So, honey flavor, for...

Casings usually contain sugar, cocoa, licorice and fruit extracts which seem to play well with tobacco when it is burned but it seems like it is alot of the stuff we are trying to filter out.

Probably that nic salt/freebase thing. According to this: Analytical Determination of Nicotine and Related Compounds and their Metabolites

I think there is something that is being overlooked with coffee filters and cotton in the bottom of syringes. I had a syringe with cotton get so clogged that I ended up breaking the syringe shaft after applying too much pressure with a caulking gun. What I am talking about is that, after a...

Nothing scientific but could it be that the toppings, being applied at the end and allowed to dry out in a short amount of time, don't have time to "blend" into the tobacco mix. Once you place it in a liquid mixture and let it sit they might mellow and turn into subtle complex flavors that...

Maybe it was because much of the flavor of smoke comes from burning. Flavors are, for the most part, water soluble so I don't think you can do this with extractions and get positive results. My extracts are room temperature 30 minute soaks and the water draws out a lot of flavor.

Snus is really just pasteurized tobacco with bicarb and salt. The bicarb freebases the alkaloids, which is why snus hit hard, ideally you would use a non-polar solvent to extract them. The problem is that these are usually avoided. Things like toluene, hexane are not things people want to be...

It would be way less efficient. A 6 or 7 ml dose of saline solution, or other medication, would take forever to push through an e-cig. Then there is the fact, pointed out above, that salt isn't going to be carried along in the vapor. If you are looking for something that is a bit more...

I really don't know. I only used alcohol once. Also, I use air dried tobacco with nothing added. I don't know if you have ever heard of casings and top dressings. Just about every tobacco product has large amounts of sugar, in different forms, added that will end up in the extract. It's just...

Sure, what falls out is what the water, or the low ethanol water/ethanol mix, can't hold in suspension. But, putting the extract in the freezer before evaporating the everclear will cause different things to fall out. One thing of interest is sugar.

Everclear won't freeze. Not in a household freezer. I think that the ice crystals that bunnykiller may have seen were from the humidity in the freezer. The stuff that forms a layer of frost on things in there. What the cold temps do is reduce the solvents capacity to hold things in suspension...

Right, the thing is that we can do both. It just takes a little more time. Personally I like water first, leave all the wax and oils behind. The effect on flavor? I have no idea. Second step, freeze filter with an ethanol/water mix. Dropped wax and oil in the first, drop sugars in the second...

Sucrose is plain table sugar and sucralose is Splenda. The amount with pure ethanol is very significant. The example I gave above shows a 98.5% reduction in sugar. You kinda lost me. Why not try what with water? I will take stab at it and assume you meant reduce sugars. Well, I just saw a...

Not sucralose but sucrose. It has nothing to do with the freezing point of sucrose. Actually it is already a solid at room temperature. What it shows is that every ml of water at room temp can dissolve 2 grams of sugar. Any sugar above that amount will not dissolve and will fall to the...
