Paste flux protects the joint area and helps silver solder wet and flow while the torch brings the work up to temperature. OttoFlux Paste Flux is a creamy white silver brazing flux that stays active and protective up to 1600°F (870°C), supporting strong wetting and bonding across a wide range of metals used in jewelry and metalworking. The smooth paste consistency spreads easily and stays stable without hardening or crystallizing when stored properly.

OttoFlux may be used directly from the container or diluted with water for a thinner consistency. Warming the flux to approximately 140–180°F (60–82°C) reduces viscosity and increases activity. Always apply flux to clean metal surfaces before heating and soldering. Residues can be removed with hot water of at least 140°F (60°C).
Avoid contact with skin, eyes and clothing. Use appropriate protective equipment, including safety goggles and gloves, and ensure adequate ventilation during brazing. Dispose of flux residues according to local and federal environmental guidelines.
