applied immediately afterward. The wooden frame was placed around the
edges of the panel; an overall vacuum was then applied and maintained for
a few hours (Fig. 12).
The panel was released and the balsa wood trimmed back to the
edge of the original. The sides were chamfered slightly and the interleaves
turned around and attached by heated spatula to the sides and back. The
sides and back were covered with a fine linen canvas attached by ironing
with wax-resin, and trimmed back to the facing edges. Seen from the side
and end, the panel now has a very slight frontal convex warp. Raking light
photographs show a considerable improvement in the surface.
Subsequently, the holes in the picture were filled and the losses
restored with Paraloid B72; the picture was then varnished with Larapol
K.80 (Fig. 13).1 The clamping table incorporates longitudinal sash clamps, together with vertical clamping
above and below. All clamps can be moved into any position laterally and vertically. The appa-
ratus has proved to be a great aid in the re-forming and rejoining of panels, especially those
with complex splits, broken joins, and uneven distortions.
