Liver of Sulphur Oxidising Gel Bottle

Liver of Sulphur Oxidising Gel

Liver of Sulphur XL Gel is an easy and reliable way to create a rich black patina on metal. It’s the same solution we use in our workshop to quickly darken metal and add contrast to jewellery pieces.

This gel formula is simple to control and easy to apply. You can brush it directly onto clean metal for targeted oxidation , or dilute it in warm water to treat larger pieces. As it reacts with the metal surface, it produces deep black and dark grey tones that help highlight textures, engraving, and surface details.

Liver of Sulphur is commonly used by jewellers to create contrast in designs, giving pieces an antique or oxidised finish while emphasising fine details.

This versatile oxidising gel can be used on silver, copper, brass, bronze, metal leaf, and metal clay , making it a handy finishing solution for jewellery makers, metalworkers, and craft makers.

The 29ml squeeze bottle makes it easy to apply exactly where you need it, with minimal waste.

Liver of Sulphur gel is also available as part of the  Premium Jewellery Tool Starter Kit ,  the Premium Jewellery Tool Starter Kit (minus tools in the Lost Wax Jewellery Tool Kit) . 

How to Oxidise Silver Jewellery with Liver of Sulphur

Oxidising silver jewellery with liver of sulphur is a simple way to create contrast and highlight surface details.

1. Clean the metal thoroughly – Make sure the jewellery is free from grease, polishing compound, or fingerprints.

2. Prepare the solution – You can apply the liver of sulphur gel directly with a brush for targeted oxidation, or dilute a small amount in warm water to create a patina bath.

3. Apply to the metal – The metal will begin to darken as the solution reacts with the surface, creating grey to black patina tones.

4. Rinse and neutralise – Once the desired colour is achieved, rinse the jewellery in water and neutralise with a mild baking soda solution if needed.

5. Highlight the finish – Lightly polish raised areas to reveal bright metal while leaving darker tones in recessed details.

This technique is commonly used by jewellers when oxidising silver jewellery to create depth, highlight textures, and produce an antique or black patina finish .
