The He-300 System is a 3-part pouring silver system. 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. The components are He-300 A Silver Solution, He-300 B Activator Solution, He-300 C Reducer Solution, and #93 Sensitizer Solution. Please refer to TDS and/or application instructions for details on how to apply. Recommended Supplementary Solutions: #87 Degreaser & Red Rouge
