🔧 What it does & how to use

An agate burnisher uses the natural stone's hardness and smooth polished tip to compress and shine metal surfaces without scratching them, making it a staple for metal clay jewellers and anyone applying gold or silver foil. It suits hobbyists learning PMC techniques as well as working jewellers finishing pieces on the bench.

• Metal clay work: Once your fired silver or metal clay piece has been cleaned up, run the flat edge firmly over the surface in smooth, even strokes.
• Burnishing action: The pressure compacts and polishes the metal grain, bringing up a bright, reflective shine.
• Foil application: Lay gold or silver foil over the piece and use the burnisher's flat edge to press and rub it down, working from the centre outward so it adheres smoothly without wrinkling.
• Finishing touches: Reach into tighter areas with the tip of the sword shape where a flat burnishing motion won't fit.
• Care: Wipe the stone clean after use; agate needs no sharpening and will keep its polished edge with normal use.
