Horosilv Silvering Powder is a professional Clock Dial Silvering & Brass Re-silvering Powder. It can create a uniform silver finish on brass clock dials with an expert-grade silver chloride-based powder used in horological restoration and metal finishing.
Horosilv Silvering Powder is a professional clock dial and brass re-silvering powder formulated from silver chloride for use in horological restoration and metal finishing.
Horosilv has a higher silver content than our traditional Antique Clock Dial Silvering Powder, making it a distinct option for restorers looking for a higher-silver-content silvering powder for suitable brass surfaces.
It is designed primarily for clean brass clock dials, chapter rings and other suitable brass components where a traditional silver finish is required.
Horosilv is suitable for professional clock restorers, horologists, antique dealers and experienced restoration enthusiasts.
The powder is simple to apply by rubbing it onto a clean, grease-free brass surface using a damp cloth and working in circular motions.
One of the main differences between Horosilv and our traditional clock dial silvering powder is its higher silver content.
Horosilv is a silver chloride-based formulation designed specifically for professional horological silvering and brass re-silvering.
This gives restorers a choice between two different silvering products:
Both products are intended for suitable metal restoration work, but they offer a different formulation and restoration approach.
Horosilv is designed for restoring a silvered appearance to suitable brass surfaces.
Typical applications include:
It is particularly suited to clock dials and chapter rings where a clean, uniform silver finish is required.
Horosilv is applied directly to a properly prepared brass surface using a damp cloth.
Cleanliness is extremely important. Grease, fingerprints and contamination on the brass surface can interfere with the silvering reaction and produce uneven results.
The quality of the finished silvering depends heavily on the preparation of the brass.
Any old lacquer, damaged silvering, dirt or other coating should be removed so that the Horosilv can react with the clean brass surface.
Once the dial has been prepared, it should be thoroughly degreased before silvering.
Do not touch the prepared surface with bare fingers. Fingerprints can leave grease on the brass and result in uneven silvering.
Where appropriate, the brass can also be prepared with a traditional spun finish before applying the silvering powder.
For engraved clock dials, any damaged or missing black wax in the numerals should be restored before completing the final finishing stages.
Horosilv is designed for simple application.
Use a clean, slightly damp cloth and apply the powder directly to the prepared brass surface.
Work the powder into the metal using circular motions, covering the surface evenly.
Work methodically across the dial or brass component rather than concentrating heavily on one area.
As the powder reacts with the prepared brass, the traditional silver appearance will begin to develop.
The condition of the brass, the level of preparation and the way the powder is applied will all influence the final appearance.
Once the desired silver finish has been achieved, the surface should be thoroughly cleaned and dried.
For clock dial restoration, a suitable finishing powder can be used where required.
Horofinish Finishing Powder is available separately and is designed to complement Horosilv and other clock dial silvering processes.
Once the silvered surface is completely dry, a suitable clear protective lacquer can be applied where appropriate.
For engraved clock dials, Silver lacquer should be applied particularly carefully and in thin coats to avoid softening and disturbing the black dial wax.
Priory Polishes offers two distinct approaches to clock dial silvering.
Horosilv is a silver chloride-based professional silvering powder with higher silver content. It is intended for clean brass clock dials, chapter rings and other suitable brass components.
Our traditional Antique Clock Dial Silvering Powder is made to an age-old recipe and has been supplied to the horological trade and clock restorers for many years.
It remains a popular choice for restorers who want the traditional finish associated with this long-established silvering method.
The choice between the two products therefore depends on the formulation and restoration method preferred by the restorer.
Horosilv is a professional silver chloride-based silvering powder designed for re-silvering clean brass clock dials, chapter rings and other suitable brass components.
Yes. Horosilv has a higher silver content than our traditional Antique Clock Dial Silvering Powder. This is one of the key differences between the two products.
Horosilv is a silver chloride-based silvering powder formulated for horological restoration and brass re-silvering.
It is primarily used for re-silvering suitable brass clock dials, clock faces, chapter rings, plaques and decorative brass components.
Yes. Horosilv is specifically designed for use on clean brass surfaces and is particularly suited to brass clock dials and chapter rings.
Apply Horosilv to a clean, grease-free brass surface using a slightly damp cloth. Rub the powder into the surface using circular motions until the silver finish develops evenly.
Yes. Thorough cleaning and degreasing are essential. Grease, fingerprints and other contamination can prevent the silvering reaction from taking place evenly.
No. The brass surface needs to be properly prepared and free from old lacquer and other coatings before applying the silvering powder.
Horosilv is intended for clean brass surfaces rather than existing plated or coated surfaces. Any old surface treatment needs to be assessed and appropriately removed before silvering.
Horosilv is formulated for brass and should not be assumed to be suitable for aluminium.
Yes, provided the underlying dial is suitable brass and has been properly prepared. Engraved numerals can be restored using Black Engravers Wax as part of the overall dial restoration process.
Horofinish Finishing Powder is designed to complement Horosilv and is available separately.
A suitable clear lacquer can be applied after the silvered surface has been thoroughly dried. This can help protect the restored finish from oxidation and handling.
Horosilv is a silver chloride-based powder with higher silver content, whereas the Antique Clock Dial Silvering Powder is made to a traditional age-old recipe and is supplied with its own finishing powder.
Both products are intended for clock and horological restoration, but they have different formulations. Horosilv provides the higher-silver-content option, while the traditional Antique Clock Dial Silvering Powder is suited to restorers specifically looking for the established traditional formulation and finish.
Horosilv Silvering Powder is currently available in 120g and 250g sizes.
Yes. Horosilv is positioned as a professional silvering powder for horological restoration and is suitable for experienced clock restorers and horologists as well as knowledgeable restoration enthusiasts.
Important: Always prepare and degrease the brass thoroughly before silvering and test the process before treating an important antique clock dial.
