4 oz COPPER-MATE PASTE FLUX Canfield Stained Glass Soldered Art Pendant Craft

This is the flux that I use in my studio and with my students. I love this stuff. Paste flux doesn't run all over your project and is easy to control. I use an acid quality brush trimmed at an angle to apply. No need to reapply if you need to leave your project for a while. Four ounce economy container will last a long time.
