SPECIAL HAZARD ALERT: Avoiding moisture contact is important
in storing this substance. Science teachers frequently report cracked glass
bottles. We suggest high humidity exposure may have resulted in the generation
of sufficient heat to crack or break the glass bottle. Flinn’s product is
not packaged in glass; however, that does not negate the need to keep this
substance dry. We package this substance in a plastic bottle. The bottle is in
a plastic bag and contained within the bag is a desiccant to reduce or absorb
moisture. Continue to store this material under similar conditions. Buy only
small quantities of this substance.
