French 1950s THERMID Bronze chrome-plated vintage coffee thermos

French 1950s THERMID Bronze chrome-plated vintage coffee thermos This is an old-fashioned French coffee thermos. The outer layer is chrome-plated Bronze and the inner layer is a glass bottle. Bronze has a good thermal insulation effect, which can slow down the cooling rate of coffee. Ice coffee can also stay colder because it has a better thermal insulation effect. There will be the disadvantage of oxidation, so its outer layer is plated with a layer of chromium to prevent oxidation, and the inner layer is made of glass bottles, which enhances its thermal insulation effect and is easier to clean. Material: Bottle cap is magnetic metal chrome plated The bottle body is made of chrome-plated Bronze(a little bit of Bronze shows up at the friction area of the mouth, no magnetic reaction) Size: height 15cm, bottom diameter about 11cm Capacity: about 230cc Year: around 1950 It can be used normally, but old parts will inevitably have historical marks such as wear and tear. Please buy it if you can accept it.
