How to test insulation quality of the vacuum flask?

• Check the inside (that is, the suction mouth) is intact, if there is a break between layers is damaged inside the vacuum, lost heat preservation ability.

• Look inside presence of blowout trace.

• See if bottle is round. If you don't round bottle, bottle stopper can't seal, will reduce the heat preservation ability.

•Fill it with boiling water and cap it.

•Measure its temperature with a thermometer every hour or two and see what the temperature graph looks like
