Imparts a patina on silver, copper, bronze and more.   Real liver of sulphur in premixed gel form, which is much easier to work with and poses no dry inhalation hazard. Ready to use after a quick shake (heat up for 15 seconds in a microwave to lessen viscosity if too cold to stir), XL Gel can be brushed on and is thick enough not to run. Convenient dispensing bottle lets you squeeze out just the right amount. Or squeeze out a small drop directly onto a brush. Minimizes odor, reduces waste. Mix one teaspoon in 12 oz. of heated water to make dark patina solution, less to make light patina solution. 4 oz. XL Gel makes 24 portions of 12 oz. solution. Boasts 4–5 times longer shelf life than dry liver of sulphur.
