Thermal carafe. The silhouette thermal carafe from Eva Solo features a stainless steel insert that makes it very robust and durable. Additionally, it is dishwasher safe except for the lid (which should be wiped with a wrung-out cloth). The thermal carafe keeps its contents hot for hours, and thanks to a practical stainless steel pouring insert, no drops end up on the table or tablecloth. Maintain the oak wood by regularly oiling it.
