so give it up. what is the "super flask"?
Are you trying to say you ahve been using mason jars for labware and have recently replced them with an unknown glass item from the floral dept costing only a buck? Damn dude go sell some crack and buy a 14/20 macroscale organic chem kit for three hundread bucks.
What is it a cheap ass vase?
BTW noting OTC would beat a "REAL" pyrex erlynmeyer flask in terms of heat shock resistance and durability. Go get on off the auction place for 3 dollars.
