Care este diferența dintre argintul oxidat și argintul sterlin?
Bine, oxidized silver is a misnomer. It sounds that you purposely oxidized silver to make oxidized silver. The truth is that pure silver or 99.9 percent pure silver is a very reactive metal. It reacts with atmospheric oxygen to form silver oxide which forms a black layer on pure silver. This gives the proof of its purity and the black color leads people to call it oxidized silver. Pure silver due to its reactivity is not suitable for cutlery or jewelry because it gets tarnished easily by exposure to air.
Argintul este un aliaj de 92.5% silver and rest copper. This alloy does not get oxidized easily that is why it is used for jewelry and cutlery.
A piece of blackened or oxidized silver is true sterling silver, but it's surface has been intentionally darkened through by introducing it to a chemical process. This patina, o culoare de suprafață care apare atunci când argintul este introdus în sulfuri, este o versiune accelerată a procesului natural de deteriorare.
Puteți oxida lira sterlină. Am folosit un produs cu sulf pentru a obține un negru frumos. Sterling este 92.5 la sută argint şi 7.5 la sută cupru de obicei. Dacă încălzești prea mult lira sterlină, poti obtine scara de foc.
