A few years ago, Emile Henry tagines were pretty unique in their shape and finish. Unlike traditional Moroccan tagines that are made with natural clay and have an earthy, traditional design, Emile Henry Tagines were the only tagines that were perfectly smooth and colored.
Nowadays, there are more and more products imitating Emile Henry tagines, and some of them are manufactured in Chinese factories giving no information about the making process or materials used to make each tagine, which is a big warning.
Emile Henry tagines are heat resistant, meaning you can use them on medium to high heat with no issue. In contrast, traditional Moroccan tagines need to be used on low to medium heat as high temperatures can make them break.
