Flux Brush
$1.00Price
A flux brush is a small, acid-resistant brush used in stained glass work to apply flux (and often patina) neatly and precisely.
What it does: Holds a small amount of liquid so you can paint it onto foil/lead seams before soldering, or onto solder lines when applying patina.
Why it’s useful: Helps you control placement, reduce drips, and avoid contaminating your main flux/patina bottle.
