Thank you for your feedback. Many people are surprised by the weight of solid copper because itās easy to assume it should feel similar to stainless steel. Copper actually serves a different purpose. Its job is to quickly transfer the cold from your drink to the outside of the mug, creating that frosty, chilled effect. A thick copper wall isnāt needed to achieve this, since copper is an exceptional thermal conductor.
Stainless steel, on the other hand, is a much stronger and more rigid metal but a poor thermal conductor, which is why stainless products often require added insulation or thicker walls.
Copper is naturally delicate, softer and more malleable, so thereās a balance between durability and maintaining the effectiveness of its temperature transfer. We use a heavier gauge copper than many manufacturers while still keeping the mug at a comfortable, practical weight.
We appreciate you taking the time to share your experience. If you have any other questions about the materials or craftsmanship, weāre always happy to help.
