High PH water and glass

SWIM knows people have suggested pyrex quality jars and the like, but if someone where to use just a jar that once held a product with vinegar and cucumbers, would that glass eventually break due to stress from having basic water in it? Should SWIM just eat more pickles?

SWIM read somewhere that it has to be a certain type of glass, where would it be shown if the glass is of the right strength or quality?
 
I wouldnt store a solution with too high ph in a glass for long.. Also wouldnt use the same containers for many extractions.. (just being safe)

but these normal type of jars are usually strong enough for a quick day extraction. SWIM always mixed did his extraction in these typical big glass pots of about 3l that some people put noodles or rice or whatever... He did all the pulls and threw it out the same day, and did this a couple of times.. if one does a few hundred grams of mimosa in an extraction, its enough dmt for personal use for a really long time.
 
SWIM left his jars with bark + ph water for days at a time... no ill effects but SWIM was worried about using them again etc. Mayhap swim should invest in perm glassware.

Nothing wrong with using pickle jars and such. Personally SWIM prefers lab glassware but many things will suffice. I don't see how base could destroy average glass.

Would a flask with a rubber stopper work? SWIM doesnt just end over end, but shakes the hell out of his water + bark. SWIM has not used lab grade in year, but SWIM knows when a lid on a jar is tight shut.
 
Disaster!

SWIM's fears came to be today as a jar broke, spilling spice, water and solvent. SWIM had just removed jar from about 120 degree water. Was this SWIM's mistake? SWIM's work area smells of a lovely vinegar fragrance to neutralize the basic water.
 
Are you talking about C or F? .

I was thinking more along the lines of going from room temperature to 100 degree C in a few seconds.

It does vary with the type of glass however. Pyrex can handle quite a bit of temp change.

Either way if you picked the glass out of the water and it shattered after a few seconds it was most likely the temperature change and nothing to do with the base.

I am not sure what you mean here but covering a flask inhibiting air exchange will cause a pressure build up if heated and shaken with organic solvents.
 
edit - def F.
Oh SWIM wanted you to know he meant that he did not want basic water coming out of the top whilst he vigorously shook said flask. SWIM has had no problems with pressure during his shakin and bake'n.
 
Glassware is not supposed to be used with a very high pH solution.
At least it's written as such in many web sites.

However,most separatory funnels are made of either PP or glass.
Maybe chemists in labs think that using it for minutes or an hour to be safe.
Anyone knows?
