Rosenthal Collection Aquiflux Self Pickling Flux 1/2 Pint for Precious Metals Gold Silver Jewelry and Hard Soldering (8 oz.)

Not recommended

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

Works great, spray on, dry and you are ready to solder.

Great

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.
