A )
Stems : metal vs mineral/organic and length .
- Stems made out of Titanium (or stainless steel ,copper,bronze,etc) do absorb more
heat from vapor than stems made out of wood,carbon fiber,acrylic/PMMA,bone,horn,etc.
Thus,the vapor is somewhat cooler.
- The XL (79 mm) stems provide cooler vapor than the standard length (62 mm) stems.
B )
Toking : Mouthpulling vs lung inhaling
- Mouthpulls are creating a negative pressure only inside the mouth cavity ,with
the utilisation of facial muscles (mainly the cheeks ) .The range of muscle movement is quite
limited ,but the negative pressure created by mouthpulls is quite big.
My own longest mouthpull is not more than 2-3 seconds.
Smoking a cigarette,sucking liquids from a straw/tube are two examples of mouthpull utilisation.
The vapor stays for a while in the mouth cavity before it gets inhaled from the lungs.
Thus,it cools and gets filtered also.Using a carbless stem on a VapCap is the same as operating
the VC with the carb hole fully closed.So,mouthpulls is the only way to go ,at this case.
-Lung inhaling is creating a negative pressure almost
throughout the whole human respiratory apparatus.
The diaphragm and the sternum muscles are utilised.
The range of muscle movement is rather large,
but the negative pressure created by lung inhalling is quite limited.
Duration of toke can go up to 10 seconds ,
with some individuals being able to extend this limit even further.
Deep breathing ,feeling the lungs before a dive,toking from a whip /balloon are some examples.
As it is understood and probably well experienced ,any draw restriction at this case
will only cause discomfort .
C )
4th gen / 7 fin Ti tip vs 5th gen / 5 fin Ti tip : A personal experience
The new Ti tip ( 5th gen ) has 20% less mass than the 4th gen tip.
That means that it has 20% less thermal capacitance ,also.
In practice the 5th gen tip is 20% faster than the 4th gen tip.
Quite small difference ,but with the use of different length Ti stems ,
it kinda makes a "statement" to a keen and experienced VC user.
4th gen Ti tip + 62 mm standard length stem : Quite a lot of vapor production,
with full "body" vapor .Somewhat hot also,with the aroma & taste being subdued.
4th gen Ti tip + 79 mm XL length stem : A perfect combination !
Lots of vapor production ,the body of the vapor is there,the taste & aroma also there
and the temperature of the vapor is just as it has to be.
5th gen Ti tip + 62 mm standard length stem : It's my second favourite option.
It's like the above combo,just with a bit more taste & aroma somewhat,but the vapor
also being a bit hotter with less body .
5th gen Ti tip + 79 mm XL length stem : A good combo for resin,oil,wax ,etc.
With this combo ,going a bit past the click will quickly increase the chamber temperature
to the extraction point ,but also will quickly start decreasing thus not allowing for mishappens.
The vapor is quite cool ,at least for the high temps involved .
Reminds of dabbing.
If used with herb ,this combo is the best option for aroma & taste (respecting the click ,this time),but the vapor lacks a heavy body .Very cool and aromatic vapor ,but rather " light bodied ".
Ideal for those with sensitive respiratory system.
