What are anodes and dura mater? What is the difference?

Anode is a layer of electroplated film, which is transparent and can fully show the true colors of aluminum products. Its film is soft, easy to scratch and cheap. Be careful not to clean with hard objects. Hard hard film, black surface, not afraid of scratching and falling, waterproof 50% (not without coating). Black can absorb heat faster and shorten baking time. The movable bottom and the solid bottom, as the name implies, are movable and can be separated from the mold, which is convenient for the cake to be separated from the mold. Suitable for making Qifeng cake, which is convenient for demoulding. The fixed cake is like a basin, and the film can't move. Mostly used for baking cakes in water bath, such as cheesecake and caramel cake. (Because there is a gap between the film of the movable bottom cake mold and the mold, it is easy to get water. )
