Developed by a scientist at the British Museum specifically for the restoration and preservation of precious works of art, Renaissance Wax is a semi-synthetic micro-crystalline fossil-origin wax that is completely free of damaging acids. This wax is ideal for use on all metals (including gilded and patinaed pieces), gemstones (including organics such as mother-of-pearl, bone and ivory), porcelain, glass, enamel, leather, wood and much more. This wax prevents tarnish and corrosion, and is highly moisture-resistant, forming a lustrous, durable, protective coating that highlights rather than obscures fine detail. The coating also creates a barrier against fingerprints and lifts away oil and dirt as well as the accumulated murky build-up left by other polishes. Completely water-proof and non-abrasive; easy to apply.
