Rosenthal Collection – Aquiflux Silver Flux for Soldering Jewelry – Low-Residue, Liquid Handy Flux for Clean Gold & Silver Joints (8 oz.)

This stuff is great. Paint it on with a brush though do not spray it. Last a while. I reorder

I used a torch at 1,300 degrees and protected expensive 14k gold-filled wire from getting fire-scale by using a generous amount of this liquid soldering flux. I won't go into the knowledge-skill needed to know how to protect gold-filled wire from fire-scale using this liquid soldering flux. This product is perfect and does exactly what it is supposed to do. To wrap this up... This flux is 100% worth your money spent. This seller/supplier is the only one I purchased this flux from. I have no reason to go anywhere else to purchase this flux. It's top-quality. The gold wire I soldered is as new-looking as the day I purchased it because of this soldering flux. At 1,300 degrees using a torch flame, the 24k soft-gold soldering chips I used flowed very, very well using this flux. You will get excellent protection from fire-scale and flow using this flux as described. It's a great product.

The flux itself is working fine but you should remove the spray head and rinse after use, otherwise it will dry and not pump. If this happens, you can get it back to working by setting the bottle under hot running water for a few minutes. You will see where it is dried or sticky in there once you remove the spray head...

Looks normal

Works great but because it is self pickeling it often turned my silver slightly pink when another metal would touch my piece. Yet, wasn't a strong enough pickeling agent to really make a difference in a good way.

Just the cap was loos and leaking but good product

I’ve used this on items I anneal - basically I spray it on before each anneal, which varies from a 3-5 times or more and the color of my metals has resisted excessive and unwanted toning. In the photos each of these ring has been annealed several times during manufacturing and whatever patina or toning you see was applied by me afterwards. I use a lot of this so I go through a bottle each week. The downside is the expense, but then again, jewelry-making isn’t inexpensive to begin with.

This is a must have for silver smiths! The spray bottle makes it great for beginners and pros alike. I definitely recommend this brand.
