Store it in a dry, well-ventilated area. While stainless steel is rust-resistant, prolonged exposure to moisture can still lead to surface corrosion over time.
The Science Behind Insulation: How Vacuum Technology Works
The superior insulation of stainless steel tumblers isn’t solely due to the stainless steel itself, but rather the vacuum-insulated construction. This technology relies on removing almost all air between the inner and outer walls of the tumbler, creating a near-vacuum space. Air is a fantastic conductor of heat; its absence dramatically reduces heat transfer through conduction and convection.
Conduction, the transfer of heat through direct contact, is minimized because there are few molecules present in the vacuum to carry the heat. Convection, the transfer of heat through the movement of fluids (like air or water), is also significantly reduced. This leaves radiation as the primary method of heat transfer, and stainless steel’s reflective properties help to minimize radiative heat loss or gain.
The quality of the vacuum is paramount. A higher-quality vacuum, meaning a more complete removal of air, results in better insulation. Manufacturing tolerances and sealing techniques play a critical role in achieving and maintaining this vacuum. Even a small leak can compromise the insulation performance over time.
Furthermore, the material of the inner wall often contributes to insulation. Many high-performance tumblers utilize copper plating on the inner wall. Copper is an excellent reflector of radiation, further reducing heat transfer. This combination of vacuum insulation and reflective materials is what allows these tumblers to maintain temperatures for extended periods.
