Review on Novacan Old Masters Flux Oz by Shawn Price

later This seems to be a great flux for my stained glass projects. Allows for a smooth solder line. A few tips (which I think apply to all fluxes I've used: no puddles!) - this eliminates the risk of spatter. Use whatever type of brush you need to achieve this. I like flux brushes but there are others that you might prefer if the flux brush has too much flux in it. Be sure to use on all seams - while most solders contain flux, I always find it best to apply a different line of flux. over it to form a solder line. Rinse off when you're done - this flux rinses off very easily (better than pastes!) and washes off with water. However, once the project is complete, I recommend using a cleaning wax to completely remove the flux so it doesn't eat at the solder and leave a matte finish.
