Borax Cone

The Borax Cone is a traditional and essential tool used by jewelers, goldsmiths, and silversmiths for preparing flux solutions during soldering and casting. By grinding the cone with water on a borax dish, a liquid flux is created, which helps clean, protect, and improve the flow of solder on precious metals. This process prevents oxidation, ensuring strong, clean joints in jewelry fabrication.

Key Features:

• Made from refined natural borax.

• Cone shape allows for easy grinding on a borax dish.

• Produces high-quality flux when mixed with water.

• Prevents oxidation and promotes smooth solder flow.

• Long-lasting and economical – one cone lasts through many projects.

Applications:

• Jewelry Making & Repair: Essential for soldering gold, silver, platinum, and other metals.

• Casting: Used as a flux to clean metal surfaces before pouring.

• Metalworking: Protects metals from oxidation during heating.

• Workshop Use: Ideal for use with a ceramic borax dish for convenient flux preparation.

Specifications (general – may vary):

• Material: Natural refined borax.

• Shape: Solid cone.

• Size: Typically 2″–3″ tall.

• Color: White / off-white.

• Use: With water and borax dish for flux preparation.

Advantages:

• Creates a reliable flux solution for all soldering tasks.

• Simple and economical method used by jewelers for centuries.

• Improves solder adhesion and ensures clean joints.

• Compact and easy to store in any jewelry workshop.
