This 7.5 Qt pot is great for making stews or for Sous Vide cooking. Columbian's technology for applying porcelain creates a durable, chip resistant product that will last most families a lifetime. The glass-like surface does not interact with or alter the taste of food, and even the most stubborn foods clean up easily. Porcelain is fused to the steel at 2,000 degrees Fahrenheit producing a non-porous, inert glass surface that is naturally non-stick. Porcelain can chip if dropped, however this does not reduce the effectiveness of the cookware. It creates a smooth, hard finish that won’t burn and resists staining. It’s also non-porous so it won’t trap odors or food particles and provides a low coefficient of friction – meaning that it cleans up easily and, it is corrosion and chemically resistant so it will last a long time. When fired, the vessel is placed on pins so the bottom and sides are hardened during the firing process into one smooth laminated glass surface. You may notice slight pin indentations where the glass has flowed around the pin that supports the base during firing. The pin marks do not compromise the finish or performance of the vessel. Not recommended for glass cooktops.
