Metal wares were so strong fixed in our interior and use that we stopped to notice and its gradual disappearance. Also we do not reflect on its features. Meanwhile, usual for metal dark color owes own origin to a way, which it воронили. Already ready, shaped subject heated on fire and roast absolutely lowered in capacity with oil. As a result of this procedure on a surface of metal which заржавевает, there was an oksidny film which not only only appropriated to a product dark color and firmly protected from water and a nepogoditsa.
For molding of ware used corrosion-proof alloys. In connection with difficulties of extraction and production, an abundance of iron utensils everyone could повытрепываться far not. Unless the Crimean khan, the collection of which iron ware at present can be estimated in the Bakhchsarai palace. But in each family respecting there was a samovar. For example, that.
Towards the end of the 19th century flight of human thought finished technical progress to emergence сталепроката, allowed in sets to let out metal in sheets, prutka and still god knows in what.
Molding of metal is used so far. Having looked narrowly, you will notice an abundance of cast metal. And not only only in monuments (on a photo a part of a monument to Nakhimov in Sevastopol and anchors in Solnechnogorsky).
Without aluminum at present while creation of furniture and lighting devices is unimaginable. Quite cheap because production becomes from clay, it besides very easy. For protection against corrosion its surface oxidize electrolit. Here the imagination of the designer concerning a collar from aluminum which owing to softness of metal is more the decorative.
The last decades products from plastic thanks to own low cost and small weight surely restrict metal in a life. Plastic of dark color and color of a patina – the made old metal, successfully masks under the forged products. Far not everyone will distinguish plastic from forging in a chandelier, trailing at a ceiling. It and is clear, after all oil while is easier for extracting, than metal. And the abundance of polymers – derivatives of oil strikes with variety. Now pour plastic, than metal more and more.
