Great value for your money & works perfectly! Must have for silversmiths.

Excellent. Works as intended

I saw someone asked a question about restoring the patina to sterling, and it got some negative responses — but I found ti to work beautifully!I am a bit of a sterling silver flatware/napkin ring magpie, and I've gotten a lot of pretty things on eBay. Sometimes the seller polishes the items before sending with something harsh like TarnX, which leaves a cloudy white cast and takes away the dark parts of the silver — even where you want it, so you can really see the details. In my experience, even leaving the flatware in question out and waiting for it to tarnish on its own didn't work. But this Liver of Sulfur really did.To use it, I grabbed a small paintbrush (an old eyeliner brush, actually) and painted it onto the areas where I wanted darkness. You can apply it all over, but it's easier to polish it away when you use as little as possible. Let it dry, and then later polish with a cream polish taking care to buff it into the smooth places and only lightly rub over the newly tarnished parts. A thin microfiber cloth works best for this, I think, because it doesn't have fibers to get in the grooves and undo your new tarnishing.It's also worked well for me on engraved pieces, like antique napkin rings. Sometimes they arrive so tarnished that getting them back to silver is near impossible without a slightly harsher silver polish, but then the engraving blends in with the rest of the silver. I've used this to darken the shallow engravings and the imprinted patterns in the silver to help them stand out — basically, removing all the tarnish and adding it back in where necessary.I've done this on about 10 napkin rings (mostly silverplate) and 13 pieces of sterling flatware. All look great! It took me ages to find an answer about how to restore the patina and I'm thrilled to finally have found something.

The gel form makes it easy to control, lasts a long time, and produces consistent patina results. A little goes a long way. Perfect for jewelry-making and metalwork. Just be sure to use in a well-ventilated area. Highly recommended!

Does NOT work on pure brass. I bought this to use on some brass, knowing it was a bit of a toss up if it would work or not, based on the product description itself ("some brass"). It does not -- but it has less to do with the product and everything to do with the metal itself. If the brass doesn't have a high enough copper content, this Liver of Sulfur won't work. And evidently my brass had little to none copper, and I'm guessing a lot of zinc.However, since I bought it already and had a mixture done, I dropped a few miscellaneous coins into it. The dimes (mostly copper and nickel) worked exactly as advertised. So giving it a 4 stars because it mostly did what it said it would -- work on some brass (depending upon the brass makeup). But it would have been nice to know before purchasing which type of brass - exactly - it works on.

The media could not be loaded. This liver of sulfur gel is great. A small amount goes a long way. Very easy to use. Use in well ventilated area as it smells like sulfur!

Is perfect for my ring making

I was trying to darken some already lazered aluminum on my motorcycle, and to my surprise, it worked perfectly!Smells bad though.. so do use gloves and a mask when using.
