Graphite Stir Rod and Anhydrous Flux Gold Silver Metal Casting Refining Set
Product Description
Anhydrous Casting Flux Borax – 8 oz + 3/8" Graphite Stirring Rod
This casting kit includes:
- 8 oz moisture-reduced borax casting flux
- (1) 3/8" x 12" graphite stirring rod
Designed for clean, controlled metal melts and smoother pours.
What This Flux Does
Borax is a trusted casting flux used during metal melting to:
- Reduce surface oxidation
- Help bind and lift impurities into removable slag
- Improve metal fluidity
- Protect molten metal during pouring
- Promote cleaner, smoother finished bars
This product is intended for melting and casting applications, not chemical refining.
Why Use Anhydrous Borax?
Standard borax contains moisture, which can cause:
- Popping
- Spitting
- Foaming in crucibles
This casting-grade borax has reduced moisture content to provide:
- More stable melts
- Less splatter
- Better control during pouring
Always preheat flux before introducing to molten metal.
Graphite Stirring Rod Included
The 1/2" graphite rod is ideal for:
- Mixing flux into molten metal
- Skimming slag
- Homogenizing alloy composition
- High-temperature use without contamination
Graphite is heat-resistant and non-reactive, making it suitable for precious and non-ferrous metals.
Suitable For
- Gold
- Silver
- Copper
- Brass
- Other non-ferrous metals
Not intended for ore smelting or assay work.
Important Safety Information
- Use proper protective equipment
- Always preheat tools and flux
- Do not introduce moisture into molten metal
- Use in a well-ventilated area
