Appearance: | No Odor, White (Platinum) Color |
Each Ingot weight: | Approximately 5 – 8 grams |
Solubility in water: | Insoluble |
Fire & Explosion: | Fire and explosion resistant |
Reactivity Data: | At ordinary and at high temperature, the alloys oxidize, but are stable. At very temperatures alloy may produce fumes. |
Eye Contact: | Flush eyes Thoroughly with running water, even under eyelid. |
Skin Contact: | Flush skin and scrub thoroughly with soap and water. |
Inhalation: | Remove person to fresh air. Assist breathing with additional oxygen if necessary. |
After proper bench set, place the ring in the oven at room temperature (or as high as 600ºF=315ºC), and raise the temperature to 1700ºF (926ºC) with one hour soaking time. Add extra time to hold time for additional rings placed in the oven.
Use Induction Casting unit or Torch Casting (gas/oxygen). For torch casting use multiple orifice tips. Do not use acetylene torch. Do not use crucible used for another alloy. Keeps the torch moving in rotating motion for even distribution of heat on the ingots. Release the casting arm when the ingots lose definition and puddle. Induction Casting set the temperature to 2700ºF (1480ºC). Set the casting arm speed between 425 and 450 rpm.
Follow the same procedure as for precious alloys. Sandblast the area bearing porcelain, and clean with ultrasonic.
Apply opaque in thin slurry. Fire the opaque slurry coating in ten degrees higher temperature. Quicker method is using the same procedure without degassing. Use opaque and porcelain manufacturer instructions
