### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great value for money, works on copper jewelry with silver solder.
  

*by S***A on Reviewed in the United States on November 14, 2019*

I am torch soldering copper jewelry with safety silv 45, I tried two types of fluxes before I found this one, one was 10+ years old and no good, the other was extremely overpriced from the jewelry making section of a craft store and gave the same results.  I thought I was doing something wrong, until I tried this one.  This works perfectly, and I can't believe how cheap it is.  I was shocked that it worked, because I read somewhere on here that it wasn't for silver, but it worked just fine with my silver solder on copper.  It makes the metal flow right into place.  Be sure to wash it off of any copper it comes into contact with when you are done.  I made the mistake of getting it on one of my copper bracelets as I was working and didn't notice untill hours later, now it needs a good cleaning and polishing.Attached is an image of a ring I soldered using this, the metal flowed right into the cracks where it is supposed to be and the joint can barely be seen.

    it Does work excellent for electrical wires too!(has no odor when you solder with it)
  

*by M***L on Reviewed in the United States on August 7, 2019*

I rarely write reviews but i was so happy about this product i had to, I didn't know whether or not this flux* would work for electrical wires but i tried it anyways, it has no odor at all when you apply heat( at room temp it kinda smells like a mint chap stick(but dont use it on your lips!), it seems to be non-toxic like the packaging says it is, its extremely cheap compared to other brands i seen on amazon, i definitely will buy this again after i run out, which isn't going to be for a long time since it comes with so much! It's such a relief finding a solder than doesn't make you feel like you're getting toxic fumes pumped in your face. SO HAPPY! ( the photos are from start to finish of how it beads on to the wire)

    Good and cheap flux
  

*by A***R on Reviewed in the United States on July 5, 2021*

I do a bit of occasional soldering on both large and small projects. If you properly tin your iron and wires and cover them in a small amount of flux, this flux generally does the job. It's easy to clean up, doesn't smell horrible and generally works.
