Double bottom cups
Double bottom
— a unique feature of double-bottomed mugs and cups is the presence of free space between the walls of the dishes. Structurally, it looks like a container-in-a-container with layers at the bottom and on the sides. Due to the presence of free space between the inner container and the outer shell, the heat of drinks is preserved for a longer period. The contents of the cup remain hot longer, and its outer walls practically do not heat up. You can safely take a mug with boiling water in your hands without the risk of getting burned.Glass mugs and cups are usually produced with a double bottom. Such double-walled dishes have an original appearance, and drinks in them are immediately perceived as potentially more delicious and desirable.
