Reliable, Clean, and Easy to Use. A Must for Stained Glass Projects
I've tried a handful of fluxes since diving into stained glass work, and this one from IMPRESA has become my go-to. It's clean, consistent, and doesn't give off an overpowering smell like some others. The included brush makes application mess-free and straightforward, especially when working with detailed copper foil or lead came projects. What stands out is how easy it is to clean up afterward. Just a quick rinse with water, and I'm ready to move on to patina or finishing. It also works great with both lead and zinc, which gives me more flexibility in the kind of projects I tackle. This is one of those supplies that quietly makes your whole process smoother. I'll keep a bottle on hand in my workspace.

The flux works good but it is transparent so I usually put to much on and don't know it. But it does work good.

Too thin
Too thin and doesn’t stick to the copper. I started using the flux paste and it works much better.

Great item. I’m new to soldering and this is my first purchase of flux but I am very happy with the product, I’ve created some jewellery items already with it. Will be a repeat customer when the time comes. Thankyou 🙏🏼
