What the Catalog Says About Microwave and Dishwasher Use
If you own the Iridescent Green Double Walled Nordic Mug or are considering one, you likely want to know whether it can go in the microwave or dishwasher. The catalog details the mug's materials and features but does not include specific instructions for microwave or dishwasher use. This means those safety details are not confirmed in the information we have.
What the catalog does confirm: the mug is made of double-walled borosilicate glass, comes with a stainless steel infuser, and includes a glass lid that doubles as a saucer. Borosilicate glass is generally more heat-resistant than regular glass, but the presence of a metal infuser and the double-walled construction introduce factors that affect microwave and dishwasher safety.

Iridescent Green Double Walled Nordic Mug: This beautiful Iridescent Green Double Walled Nordic Mug™ is made of double-walled borosilicate glass and comes with a stainless steel infuser and a glass lid that doubles as a saucer for super convenient steeping. The double-walled design and stainless steel infuser are key factors when deciding about microwave and dishwasher use. Metal should never go in a microwave, and the double-walled construction may trap water or be sensitive to high heat in a dishwasher.

Microwave Safety: What to Consider
Because the mug includes a stainless steel infuser, you should not place the mug with the infuser inside in a microwave. Metal can cause sparks or damage the appliance. Even without the infuser, the double-walled borosilicate glass may not be designed for microwave use — the catalog does not state that it is microwave safe. If you want to heat water in the microwave, it is safer to use a plain microwave-safe vessel and then pour the hot water into the mug for steeping.
Dishwasher Safety: What to Consider
Similarly, the catalog does not confirm that the mug or its components are dishwasher safe. Double-walled glass can be more fragile in a dishwasher due to high heat and strong detergents, and the stainless steel infuser may be affected by harsh cycles. Hand washing is the recommended approach to preserve the mug's iridescent finish and the clarity of the glass. Use a soft sponge and mild dish soap, and dry with a soft cloth to avoid water spots.
Best Practices for Everyday Use
To keep your Iridescent Green Nordic Mug in top condition:
- Always remove the stainless steel infuser before any heating or cleaning decision.
- Hand wash all parts with warm, soapy water and a non-abrasive sponge.
- Avoid sudden temperature changes — don't pour boiling water into a cold mug or place a hot mug on a cold surface.
- The glass lid doubles as a saucer, so you can rest the infuser on it after steeping without making a mess.
These simple steps will help maintain the mug's beauty and functionality over time.
