A high efficiency (HE), 3-part pouring silver system used extensively by the hand silvering and recording industries. Because of its improved glass adhesion, it deposits more silver with less waste. The slower deposit rate of this system is ideal for the inside of blown glass, bottles, and glass aggregates. It tends to produce a “warmer” toned, but robust silver. Good for antiquing. Kits consist of He-300 A Silver Solution, He-300 B Activator Solution, He-300 C Reducer Solution, and #93 Sensitizer Solution. If purchasing separately, do keep in mind this He-300 C Reducer is designed to pair with the other recommended solutions in the suite.Please refer to TDS and/or application instructions for details on how to apply. Recommended Supplementary Solutions: #87 Degreaser & Red Rouge
