[gutokuhn]

[sleii1990]

vlw irmão pela resposta =)

mais dando uma pesquisada axei essa receita e to tendo otimos resultados:

"Uma solução simples para limpar prata é combinar aproximadamente um litro de água, em temperatura ambiente, com três colheres de sopa de bicarbonato de sódio e três colheres de sopa de sal em uma tigela. Adicionamos um pedacinho de papel alumínio e imergimos a prata nesta solução.

A prata vai brilhar de novo"

That spoon is worth around $18 now if its pure silver.

por el azufre, la plata que se "ensucia" es plata sulfurada, y la yema de huevo tiene una gran riqueza de azufre, hace 3 semanas que mandaste el comentario... pero lo contesto ahora, que acabo de verlo

[MUDSWAT]

The silver spoon turned black from Sulfur Dioxide or the sulfur in the egg... The soda salt, water and foil lifts the sulfur off the silver and transfers it to the foil.

nice video-thank you

[winfriedstar]

wie alt?

[andygray]

What is the chemical reaction between? Baking soda and the aluminum foil or common salt?

[TheEye002]

salt=NaCl

[DiiDee66]

what was the egg about?

[neothemagical]

I think the egg white provides the sulfur necessary for the silver to tarnish... but I'm not sure...

[tukoyz]

mao ba?

[Zuchtsau]

was ist das für ein salz? ich würde das für meinen ring brauchen!

[Netexperimente]

Du brauchst nur Kochsalz. Wesentlich ist aber die Alufolie. Leg die in ein Glas, gieß heißes Wasser hinein, etwas Salz dazu und dann mit dem Löffel umrühren. Genauere Infos findest du auf der HP, die am Ende des Videos eingeblendet wird.
