Is the glass liner of thermos bottle better or stainless steel?

Which is better, stainless steel thermos or glass thermos? From two aspects, one is thermal insulation performance, and the other is safety. As for heat preservation, I think stainless steel has better heat preservation performance, but personally, I think the glass liner is safer and healthier, and there is no odor.

When I was a child, the inner container of the thermos at home was all glass. If I accidentally knock it down, it will break the glass and will be criticized before long. I used to think it was not good at all, it was too easy to break down, but the insulation effect was really good. The water boiled at night can be stored until the next night without breaking the hot water.

The heat preservation effect of old-fashioned glass inner container thermos depends on the quality of vacuum double-layer glass inner container.

Boiling water, after boiling for five minutes, is put in a thermos bottle with a glass liner, and the mouth of the bottle is plugged with a cork, and the mouth is still hot after 24 hours. Modern science and technology stainless steel liner thermos bottle adopts food-grade 304 stainless steel as liner, and the shell is filled with heat insulation layer (or air heat insulation and heat conduction), which has the same heat insulation effect!

As far as household use is concerned, the glass inner thermos bottle should not be swaggered, but can be placed on the coffee table, and hot water can be poured at any time to make tea!

Stainless steel inner container thermos can be taken out or exercised at will, and can climb mountains and wading, run and keep fit, replenish water anytime and anywhere, clean and hygienic!

Stainless steel inner container thermos with smaller capacity, more expensive price and more convenient to carry; Glass vacuum liner thermos bottle, with larger capacity and lower price, is a family necessity for children and the elderly. Drinking warm water often is good for health!

Many people don't want to use the glass liner because they think it is fragile. But now, if the glass liner is made of good glass with high heat resistance and explosion-proof coefficient, there is no need to consider the problem of fragility and explosion. Glass liner is safer than stainless steel, and drinking water will not be doped with harmful substances. It is recommended to use a glass liner thermos.

There is also a thermos bottle with a hollow resin liner, which is also very good, light in weight, warm and not easy to break.
