Lowy’s antique and reproduction frames represent various historical periods from the 15th through 20th centuries. The process of creating a gilded reproduction frame starts with the entire frame designed on paper, which is then carved in wood. Wood is one of the most common and useful substrates for gilding because it is stable over time and because it is true to traditional techniques. In accordance with fashion, culture and custom, frame makers have worked in a variety of woods such as pine, poplar, oak and limewood. In the 19th century, the newly developed material called composition, a thick moldable mix of rabbit skin glue, whiting, linseed oil and rosin, gained popularity for its ability to mass produce ornament. Composition made it possible to make complex frames with many different designs because the ornament could be cast into molds and applied to the frame, instead of being hand carved.

Even when elegantly carved, bare wood is irregular and must be smoothed before applying gold. First, we apply a layer of rabbit skin glue to ensure that bonds will form properly. Then, we brush on 10-12 coats of warm liquid gesso, a protective covering typically made from calcium carbonate or calcium sulfate, water, rabbit-skin glue and sometimes linseed oil. After the gesso dries, it is sanded. Next, we apply layers of traditional bole, a fine particle clay also mixed with rabbit skin glue. The bole, which is usually yellow, red or grey, will over time start to show its color through the gilding due to abrasion of the finish. When applying these base layers, gilders must balance even coverage with maintaining detail, keeping the original design intact. Sometimes this requires that we recut the design by carving back into the gesso layer to redefine or augment the ornamentation.
Lowy has facilities for antique frame reproduction, carving and gilding. That’s one of the reasons why we have been sought out for frame fabrication and restoration projects for such a long list of venues, ranging from government buildings to private collections and public exhibitions.
