you can boil water in a paper cup! over an open fire should you choose…

the temperature of your container will not exceed that of the liquid boiling in it. that is the physics of boiling. it removes energy from the puddle.
you can get decarboxylation in ethanol at 78C, but it takes a while. eg I get full decarb when recovering 15gal over the course of 12-14hrs. but only partial decarb if I recover 1/2 that (so 6ish hrs dwell time)
Are you concerned about decarb? it needs decarbed to “work”. Eat it/vape it/Dab it is only relevant to decarbed. I run decarbed eho in my vape pens, when not running live resin in one of these
check this thread for using a store bought water distiller for recovering ethanol.
if you’re not concerned about recovering your solvent to go again, you can remove it with a rice cooker (I pay $5 for them at the second hand store). This is usually how I set folks up for “home use” style production.
it won’t be decarbed when it shuts off, but you can achieve that if you desire.
1/2 gal ethanol, 1/2lb biomass. Big jar, large french press, rice cooker.
if you want a “shatter”, then you’ll need to evaporate slower…rm temp with a fan works for those on a budget.
