Carved Console and Mirror

      This project involved attaching metal leaf to the visible surfaces of this walnut, hand carved console and mirror. This process is called gilding, or more specifically for this project oil gilding. The goal was to create a traditional looking gilt object that showed characteristic signs of aging and use.  Treatment involved an initial cleaning and degreasing of all surfaces to be gilded.  Scuff sanding of the surface was then performed to ensure proper adhesion of the subsequent surface materials.  In order to mitigate the expensive cost of (gold leaf) material over such a large amount of surface, I developed a method to use a combination of  23.75 k gold and composition metal leaf, which I purchased from http://www.seppleaf.com/.  The composition metal leaf was attached to the recessed areas using a fast drying oil size.  These areas were initially sealed with a coat of shellac and later glazed to "age" or darken and diminish the subtle color differences between types of leaf. 
    The more prominant foreground areas were first coated with an oil-based, red primer coat, and smoothed before the gold leaf was attached with a slow drying oil size.  Unlike composition leaf, which can be easily handled, gold leaf requires special tools to work with.  Some of these include a gilders pad, knife, and soft, natural bristle "tamping" brushes to ensure the gold is carefully adhered to the surface.  Because this process is time consuming (the console portion took 99 hrs!), and the size has a limited working time, dividing the piece into smaller areas of work was necessary.  After all the surfaces were covered in leaf, an additional dark brown oil-based glaze was applied.  Lastly, a coat of clear paste wax was applied using a range of buffing pressures to rub-off some gold leaf on prominant surfaces.

Georgian Corner Washbasin

                                                                                                     This Georgian Mahogany corner washbasin had severe structural damage to the lower shelf and drawer. The tenon joints were shattered from numerous nails being driven into them and were hanging below unable to support the drawer.  The rest of the piece was firmly glued together. Also the top front edge was missing a few inches of veneer. 

The lower shelf area was disassembled completely and new material was attached to the lower rails ends behind the veneer face.  This material was then shaped to fit into the corresponding mortises.  The skinny, flexible nature of the legs enabled me to insert the lower shelf support with its new joints, without having to disassemble the entire piece. The drawer runners and fixed side panels were then reattached using fish glue.  New pieces of mahogany veneer were cut to fill losses on the top front edge.  These new pieces were then toned with Earth pigments and sealed with shellac to match the surrounding area.  The entire piece was then coated with paste wax and buffed.

Lacquered Chest







This tall chest was treated for flaking gesso groundcoating and some losses of the lacquered surface design.  These areas were concentrated around the drawer edges, probably due to routine use.  First the loose areas of gesso groundcoat were re-adhered to the surface using a rabbit skinglue solution.  Next the gesso filling material was prepared using an historical recipe of  chalk and rabbit skinglue.  The heated gesso is then brushed into the lost areas in layers to build up the surface.  Once the gesso has thoroughly dried it is shaved to the height of the adjoining surface using a sharp chisel.  The white fill areas were then inpainted to match the existing faux tortoise shell lacquering with a shellac medium and earth pigment powders from Sinopia Pigments and Materials.
