Alex Carlisle presented a fascinating and detailed treatment of the pulpit in Fort Herkimer Church, German Flatts, New York (http://fortherkimerchurch.org/7.html). The church has a long history; the current structure dates to 1767, with many additions and expansion in war and peacetime. The pulpit was added in the early 19th century, and seems to be completely unique; it is made from white pine, but nothing is known about the workshop.
During a recent, major renovation of the church, white paint coating the pulpit was partially sanded off and discovered to be covering polychrome decoration. At this point, Carlisle was asked to work on the project, to remove the remaining white overpaint and preserve the original polychrome layer. At least one coat of white paint was lead-based, and very intractable; the majority of this was mechanically removed. Fortunately an older resin coating layer was present, and the lead white paint tended to cleave off at the interface.
Once the white overpaint was removed, the remaining original surfaces were consolidated and coated with a barrier layer. Losses in the polychrome ornament were inpainted to re-create the original decorative effect. So far the base and main section of the pulpit have successfully been treated; the canopy awaits funding to complete the project (keep an eye out for part 3!)
