Thermoses with glass flask
prices on 21 model
— this material is typical for thermoses that are not intended for use in any difficult conditions: glass flasks are very fragile and can crack even from a relatively weak push. At the same time, in home and other similar environments, such vessels will be at their best: glass is completely chemically inert and does not spoil the taste and smell of the contents, and its thermal conductivity, although high, is still lower than that of steel. In addition, the inner surfaces of the flasks are often made mirrored, which further reduces heat loss.
