Frequently Asked Questions (FAQs)
1. Why is a flask best for heating?
They use a double-wall construction, separated by a cavity, which creates a thermal insulation layer that keeps liquids hot for longer. The same vacuum principle applies to keeping drinks cold, so double-walled flasks are also a great way to keep drinks ice-cold on a hot hiking day.
2. Can we pour cold water in flask?
A cold thermos flask will not break when you pour cold water into it. Note that it is by no means guaranteed that a thermos flask will break in these conditions. Local flaws, scratches or pre-existing micro-fissures in the glass probably initiate/exacerbate the breakage.
3. Is thermo flask for hot and cold drinks?
VACUUM INSULATION: The ThermoFlask keeps beverages ice-cold for 24 hrs, and hot for up to 12 hrs with double-wall and vacuum insulation.
