Flux - Firescoff Ceramic Nanotechnology (120ml)

I love this product! I was introduced to it as a flux that only worked to prevent fire scale, but find it to be wonderful for soldering. My solder flows much more easily than with any other flux I've tried over a decade. It is also cleaner--much less smoke than other fluxes, thus it's a safer option. It is definitely pricey, but since I spend a lot less time soldering and also end up wasting less solder, I think it's well worth the money.

This does exactly what it promises. You can even use it to mask areas when creating a heat patina. I was advised to try using a brush for small areas, to conserve product, since its a bit expensive.By the way, the merchant sent me the wrong size in error, but CALLED. me to apologize and sent the replacement "post haste" --and told me not to worry about shipping the smaller size back. That saved me the inconvenience and was really appreciated. Quick shipping and Great customer service!

This stuff is "worth its weight in gold"! It makes soldering a breeze! I highly recommend this product to anyone who is getting into jewelry making or has been it in for some time. It has helped my soldering skills go to the next level!

Boy is this stuff expensive. Works somewhat and only on silver.

I had no idea just how terrific this product is until I ran out; then I could see how well it had been protecting my jewelry metals from firescale- and how much easier my pieces cleaned up. I'm ordering another bottle without searching for a different product.

Life saver

Bottle was faulty and did not spray. Company refunded $10 .I'm sure the product is good. However the bottle isn't.Very disappointed.

I love it!
