Healthstone and hot air

[Chance4373]

I'm new to posting here but not new to the art of vaporizing spice. This community has taught me so much that I thought I should give back, at least in a small way, by sharing my setup. Many great ROAs have been described on this forum so forgive me if none of this seems novel or new. I've found this setup delivers exact dosage every time and creates little guesswork. Additionally, with pure spice this setup results in almost no taste on inhale.

Required items are a torch lighter, Healthstone pipe, milligram scale, and a rework solder heat gun.

Weigh dose using milligram scale and transfer to the center of the Healthstone. Melt the spice using the torch lighter by aiming the flame toward the spice while keeping the flame 1/2" away from the material. The goal is to melt, not burn the spice so make sure the flame is not touching the material. You want to see all of the spice melt so it doesn't blow away while using the heat gun.

A good rework solder heat gun allows air flow and temperature to be controlled and has a stand that shuts the heating element off when the heat gun is returned to its base. Set airflow to between 50 and 100% and the temperature to 650F (approx. 340C). Once heat gun is up to temperature, point the tip into the stone roughly 4 or 5 mm above and inhale deeply as if trying to take a breath through the pipe. Vapor will start traversing the pipe then stops once all of the spice has vaporized. Hold in your lungs until you exhale no vapor (about 10 seconds). Done this way there is no taste just the feeling of warm air on inhale.

This method is nearly fool proof but it is not without risks. The heat gun is obviously designed to melt solder so only do this if you have someone with you to help in case you fumble putting it away. Alternatively, the torch lighter works as well but burnt spice becomes a possibility if the flame is held too close to the stone.

Many thanks to all of the psychonauts here that have shared their wisdom. Hopefully, someone finds the above info useful.

Cheers

Salutations,

...rework solder heat gun.

How about this:

Airflow can be set down to 3.6 cfm...

This method is nearly fool proof but it is not without risks.

Although a heat gun won't provide conduction energy and still imply variations, while i don't do DMT anyway, it seems to me the key to precision dosing is likely to reside in « packetization » of the energy budget - which depends on this universal law of dame Nature:

It appears that energy transfer variations can be dealt with by conveniently separating the pre-heating phase (#1) of noble molecules from their release/transport (#2) using convection, by building up the blow as a function of temperature, mass and specific heat exactly:

A "healthstone" will convert thermal mass into convective energy after raising temperature of your noble molecules temperature, yet for optimal performance i must point out that Silicon Carbide Foam is a nearly ideal material which is chemically inert while its microscopic arms massively connect the foam's air pockets which quickly transition from a state of collective insulator to convective heat source. The pre-heat phase would presumably cause premature energy transfer to a workload but i figure some tiny airgap separating 2 slices of healthstone or SiC Foam might work just fine if only 1 of those gets the full heat while radiating on the other.

Perhaps ready-made devices offer alternatives, i'm thinking of the rejuvenated VapMan Click where conduction is the main energy source, assisted by airflow and i guess some convective heat for transport. The "e-Mesh" solutions also attracted a fair bit of attention in previous years. YMMV!

Personally i've regained enthousiasm about IH scenarios after having an intuition confirmed by this old video:

Greetings and Merry Christmas to you!

I've seen induction used in some dab rigs and it appears to work great! They heat up quickly (as your video points out) and could be dialed in to work flawlessly. I don't have personal experience with this method so opted for a setup that can be had with a few commercially available items.


The heat gun you mentioned would almost certainly work but the orifice is a little larger than what I wanted to use plus I like that the rework gun turns off when placed back on the stand.

This is more along the lines of what I have found works:




By properly controlling the temperature and airflow you can achieve vaporization without the undesirable burning that can occur when using a flame. Spice will react with oxygen which is why the sandwich method has been used successfully by many since it limits the amount of heat and oxygen that would burn it.

The boiling point of spice at atmospheric pressure is not known due to decomposition and has only been measured at reduced pressure. Although, spice does have a vapor pressure estimated to be about 3.1X10-4 torr at room temperature so it can be vaporized below it's boiling point to prevent decomposition. I think this is what is occurring when using a heat gun. Other resources in the Nexus suggest lower temperatures are better but I've found the hot air from the heat gun at 300C or higher has worked every time and leaves no taste in the mouth or residue on the stone.
