have friends who use both heard glass can break when using lye what do you all think would be all around safer

Yes glass can break that is why you want to use thick glass and do it over something like a sink just in case.
You can also use lab grade borex. Use thick glass!
You do not want to use HDPE2 because endlessness has shown that plasticizers can leach into the naptha and the DMT product which are carcinogenic and should be avoided.

Mixing lye and H2O is an exothermic reaction. Glass that is not borosilicate might not withstand heat. Mix slowly and allow to cool and there shouldn't be a problem. I think there are trade offs for using either.

U got a link for this?

Yes sir.

Ide really like to get a glass mixing container but I cant help but think the rubber around the lid will degenerate from a base.

not all plastics have phthalates, but other monomers may be leeched into the solvent.

so would you say your average mason jar is safe to use or what should i use?? i want to be one hundred percent safe after a revent accident i heard about from aFOAF

it's safe for a quick extraction, but don't store very basic liquids in it; silicates will complex with the cations of the dissociated base (the so-called etching)

what about a rubber seal?

im not trying to sound redundant but a mason jar is safe but i shouldnt store lye in it? can i still freeze evap in a mason jar if i use naptha? safely??

Lye will cause etching on your glass jar, but as far as i know, naphtha doesnt eat away at glass.

yes

so then what is the safe alternative i dont wanna be ingesting more glass.....lol

im sure youde be fine with quick extracts, and its not like you will be vaporizing the glass.. ide be more concerned about what effects lye has on a rubber seal of a glass jar.

well how likely is the lye going to breakthe glass never seen it happen but know that i have read abot it i guess you could say i have thefear lol

rubber is comprised mostly of nonpolar molecules; organic solvents are more destructive to rubber than aqueous base.

I think it only breaks when a solution of lye and h20 is made, and under pressure, the jar breaks. I dont see a problem, if you dont let pressure build up.

Isnt naphtha an organic solvent?

so after shaking should i open it let it sit a sec re cap shake uncap and repeat a few times??
