We had the privilege of restoring the acanthus leaf frame shown below for the Municipality of 's-Hertogenbosch. The frame for the painting by Piet Slager Jr. hangs in 's-Hertogenbosch City Hall on the market square. This type of frame derives its name from the feather-like Acanthus leaf and was widely manufactured in the second half of the 19th century and early 20th century.
The frame was missing many ornaments, and over the years the bare areas left by these missing pieces had always been painted over with gold paint. Also, the joints between the ornaments and the wooden base material were broken in many places. Once in our atelier, we stripped the frame of its layer of dirt and tarnish and removed all the oxidised gold paint. Next we re-established a strong connection between the layers by injecting bone glue. With the aid of moulds, we recreated the missing ornaments and placed them back on the frame. Traditional water gilding was originally used for the frame. After all the ornaments were complete again and the diamond motif on the convex border had been reinstated, the restored parts and areas were colour-matched to the original gilding.
