8oz Liquid Zinc Flux for Stained Glass, Soldering Work, Glass Repair and more - Easy Clean Up - Made in USA

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 🙏🏼

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.

Works well for my stain glass
