Metal Polishing Myths, Half Truths and Lies
Green rouge and white rouge are similar to jeweler's rouge
Nope! Sorry, no such thing as green or white rouge, I don't care what any one tells you.
Many manufacturers in the industry don't appreciate this, they call anything in a bar jeweler's rouge - but 'rouge' is French for 'red'. jeweler's rouge is red because it contains ferric oxide. If it doesn't contain ferric oxide, it's not rouge.
jeweler's rouge was developed not just because of how fine it can be, but also because it stains the gold and gives it a sunny glow. Green and white rouge, as many people call them, are abrasive compounds, which are in most cases way too coarse to be used on gold or anything else of value. If you offered them to a jeweler as rouge, he would laugh at you.
For a start a good quality jeweler's rouge is three times the price of any other compound. There are some abrasives which are as fine as jeweler's rouge and finer, but they don't behave like jeweler's rouge, and jeweler's rouge they are not!
Because of this generalisation I have seen very aggressive abrasive compounds being sold as products that were suitable for use on jewelery and precious metals. Not good!
