1 Ounce (30ml): Sample size.

34 Ounces (1000ml): For multiple jewelers and production shops.

Gently heat the jewelry to 250°F (120°C). You can gauge the temperature by placing a drop of water on the metal surface. Apply heat until the water boils off completely, then apply Firescoff Rh.
Apply Firescoff Rh at the start of the repair to protect rhodium. Spray so that a fine mist coats the entire piece. When applied correctly, Firescoff will form a uniform white powder coating instantly on contact.
Gently reheat the coated jewelry. Apply more Firescoff Rh if a reflection from the metal is still visible.
Because Firescoff Rh also performs as a flux, no other paste or liquid is required. When using paste solder, apply paste solder first, then apply Firescoff.
Remove Firescoff Rh coating after resizing or repair easily using just warm water, or an ultrasonic bath. No acid pickle is required.
Note: At low temperatures, or if
the bottle seal is broken, ceramic
crystals may form at the bottom
in the bottle. This may temporarily impact pump/spray performance.
To return crystals back into solution, place the entire bottle in hot water or heated ultrasonic bath for 10-15 minutes.
