Borax Cone - Flux

Borax is a jeweller’s go-to flux, simple, effective and reliable.

It helps prevent oxidation on the surface of your metal during soldering, ensuring cleaner joins and better flow of solder. Affordable and long-lasting, a single cone will see you through countless projects.

One of the great things about borax (and why we use it in our classes) is how it gives you visual cues while you work – as it heats up, it changes both colour and viscosity, letting you know exactly when your metal is reaching the right temperature.

This traditional borax cone measures 5cm across the base and 12cm tall, making it a solid, long-lasting addition to your bench. To use, simply grind a small amount with water on a borax dish to create the flux paste, then apply to your workpiece before soldering.

An essential tool for both beginners and experienced makers, borax is a classic studio staple you’ll always want within arm’s reach.
