decarbing is mostly counter productive, and is really only degradation. it gets decarbed when it reaches boiling point and travels to your lungs or other mucous membranes.. one could say that a slow enough decarb would give more thc than decarbing at 500° almost instantly (a bic lighter) ..however even if you did that, it still must be hit by the same high heat .... and any decarbing before hand is just degradation
what frenchy is really attempting to do with the heat and pressure of the wine bottle...if thats what yall are referring.. is to melt and homogenize the hash, this makes it smoother, taste better and its cleaner..ill explain
any possible plant matter that made its way through will be broken down-
secondary metabolites are toxic and must be held in a storage cavity to prevent cell death and indeed "thca and cbga cause 100% cell death in 10 day old suspension cultured cannabis sativa cells at 50um(through apoptosis). The cannabinoid precursors do not have this effect and some can be found in leaf material The results of reverse transcription pcr and heterologous expression suggest that THCA synthase is localized in the apoplastic space of the glandular trichome only"
this apoptosis-little cellular explosions i suppose.. as i said, "cleans" the hash and smooths the smoke, the waxy heads when combusted, are harsh and acrid
the movement, pressing with the bottle, folding and repeating.. also allows oxygen to better reach the active compounds(and temp speeds the processes) as well as the favorful terps esters etc (many of which are also psychoactive) that would normally be trapped behind the waxy head, slowing this process.. this technique aids cyclization and formation of new and additional "desired" products including terpenes..
also, when the trichs are in this... mixture whatever you want to call it, patty lol. less o2 and heat reaches each trich head(if you were just smoking sift), while smoking..less surface area giving a smoother and cooler smoke as you burn it, and makes it easer to dab.. infact it may even "perma goo" with the temps as alot of rosin does, which many people assume is better quality, visually its more appealing and resembles a terp filled extract as they have much lower melting points..gooey.. however this is not what thats from necessarily, hence "perma goo" the compounds are actually forming an azeotrope pulling water from air, they are hygroscopic
*im not talking bad about any tek mentioned..not everyone "burns" or combusts there hash..etc, dont play word games with me lol. i didnt go into pros and cons for a reason
my little penny..
hope it made your dollar
