The super-durable and lightweight Meramid roasting pans with a superior heat conductivity are ideal for roasting and baking. The unique outer layer of Samuel Groves’ Mermaid Hard Anodized range hardens as an electrochemical process results in a dark finish. In particular, its surface is twice as tough as stainless steel and will never blister, peel, or flake. As time goes on, if used properly, our hard anodised products will develop a patina that makes them nearly non-stick. Professionals use aluminium as a heat conductor because it heats up quickly and consistently bakes evenly.
