Copper universal metal. He found his application in heavy and light industry. Electronic industry is not conceivable without it. Even in the food industry, metal is used with success. And all this thanks to the high conductive properties. Copper has high electrical wire properties, and the same, high thermal conductive properties. It was thermal conductivity that made it possible to use non -ferrous metal for the manufacture of dishes.
Over the years of our time, archaeologists do not cease to extract copper pots, pans, boilers, stewpan and other kitchen utensils from the surface cultural layers of the soil. This dishes prevailed in the kitchens of our ancestors for centuries, and they understood in cooking and versed in the properties of metals.
Another metal has the same unique characteristics – this is silver. But its high cost does not allow it to be used everywhere for the manufacture of dishes. Piece products are made from it, which can be attributed to the category of collection things. Buy pots or silver buckets can afford people with good income. However, how often will they use them? Remember the silver spoons. Throughout the year they lie in sideboard or drawers, waiting for holidays.
Many years later, copper began to be replaced by cheaper materials. Aluminum, steel and cast iron replaced her. Later, glass dishes appeared and ceramic utensils resumed its life cycle. But it was not possible to completely abandon copper. You can still find Jezva stores on copper coffee on the shelves. Copper is found in many alloys used in the production of kitchen utensils.
Metal is still used as an excellent heat conductor in the manufacture of a multi -layer bottom. Buy a set of pots with such a bottom is dreamed of every woman. After all, nothing is burning in them. The reason for this is the uniform distribution of thermal energy over the entire surface. As a result, critical points of overheating are not formed during the preparation process.
Copper can still be found in the form of dishes. As indicated above, this is jezva and Turks. And samovars? And they also meet. But in most of their part their alloys are made. So that pure copper does not react with food, the inner surface of the dishes is ate. Use food tin. But mainly red metal is used as a core, in multi -layer designs of dishes.
