Baroque Zinc is a lead-free, preweathered patina on zinc sheet metal. Baroque Zinc is a reference to the historic detail used to produce exuberance, drama and grandeur. The sophisticated patina evokes the artistic styles of centuries past. Like the art and architecture from the historic period, zinc is an expressive material which conveys an emotive response.
The patina process is proprietary and developed by Zahner as a lightweight material for cladding and fabrication. A patinated zinc surface such as Baroque, Roano, or Hunter will serve to protect the metal surface from deterioration.
Baroque Zinc is a sustainable material made using sustainable practices. The material is produced in Zahner's award-winning, EPA compliant facility. Patina effluent is properly captured and disposed of in compliance with local, state, and federal regulations. This ensures the health and safety for the families who work at Zahner, as well as the community at large in which it is made.
Patination of Baroque Zinc
Baroque Zinc is cultivated on raw zinc sourced from the only American-made zinc supplier of architectural sheet: Jarden Zinc. It can be produced at thicknesses from 0.5mm to 3mm, at sizes up to 43"x160”. The material is available in sheet form, but any forming or fabrication processes altering to the metal surface should be performed prior to application of the patina.
Zinc is a transformative material, meaning that it will oxidize and develop a patina layer over time. This patina provides the zinc with a passivated oxide layer, a protective barrier that protects the zinc surface from further deterioration.
If properly installed, zinc surfaces can last more than 100 years. Left to its own devices, raw uncoated zinc will either grow lighter or slowly darken as it reacts to environmental conditions. If exposed to prolonged contact with direct moisture, the metal’s outward face may be susceptible to white-gray areas and/or streaking; this condition can occur with or without a patinated surface. Under typical conditions, patina color will darken, creating a rich umber feel over time.
If exposed to moisture over time, the back face of zinc material may suffer from perforation or disintegration of the surface; to ensure best performance, the verso may be covered with plastisol or a similar coating to mitigate potential damage.
