Novacan Old Masters Flux - 8 Oz

I apply this with a paintbrush due to it being thin enough. Its good quality and you get a good sized bottle. It doesnt stick to my paintbrush, so its easy to use. The liquid basically doesnt have any weight to it, so make sure you know where you've applied it because you will not see it like a gel flux. And definitely wear gloves.

Works great

Seems to be a great flux for my stained glass projects. Allows an even solder line. A few recommendations (which I find to be true of all fluxes I've used): Don't use too much- you want to "paint" a wet line to the copper foil, no more (there shouldn't be any puddles!)- this will remove any risk of splattering. Use whatever type of brush you need to to achieve this. I like flux brushes, but there are others out there you might prefer if flux brush gives you too much flux. Be sure to use on all seams- although most solder includes flux in it, I find it's always best to paint another line of flux over it for a beaded solder line. Wash it off when you're done- this flux washes off very easily (better than pastes!!) and rinses away with just water. When the project is done, though, I recommend using a cleaner wax to fully remove the flux so it doesn't corrode the solder later leaving a dull finish.

This is a great flux when working with stained glass.

Best product to buy. Makes soldering much easier.

It's pretty good flux, works well. Cleans up with water, so just rinse your piece when you are done. Very simple. The fumes are quite noxious, and inhaling them sucks for sure. Some people say that they find it spatters a lot, or makes a mess. This is only true if you use too much and it pools up. An easy way to prevent this is to use something like a cotton swab to apply it rather than a flux brush, as you can better control the volume. Also, it will spatter when filling cracks/voids as the bubbles/flux interact.

The Flux arrived shortly after I ordered it. It works great for my stained glass.

It works great.
