After testing every Silver solder Flux we could find, we found this cream flux to leave the nicest and smoothest joints the first time. This Silver Brazing Flux is excellent when fixing broken keys or for other hard soldering applications. It protects parts from oxidation and also slows discoloration. The working temperature range is 1100-1350 degrees Fahrenheit or 593-732 degrees Celsius. You can use hot water to remove any excess flux. If the flux dries simply add water until creamy.
