I received two 1000ml flasks.first one i put on the hotplate with sulfuric acid as soon asthe hotplate got hot the glass cracked and it was a disaster,,,, toxic smoke everywherenext day. second one on hot plate. same thing withing two minutes.these are not safe and should not be sold as anything but a flower vase.my guess is made in china of course.
