The runners are cleaning up well.

The paint re-adhered wherever it was flaky ("consolidated"), initial cleaning of the runners involved the use of a kneadable eraser that we developed for the purpose (of methylcellulose base), followed by an aqueous cleaning.   Solvent cleaning will follow, in a later step.

Cleaning Neptune's face

At the front of the runners of the Siren sleigh, Neptune's face has been mostly cleaned on one side (at left in the photo); the other side still has about 200 years of grime !

Starting to clean the sleigh's runners.

After cleaning tests on the runners, I proceeded to clean them.
The left side of this photo shows the results (on the right the runner remains dirty).

Nobody's got bling like the King.

I returned to Versailles, after my short trip to Wales (I'm actually not working in the Big House, but in the stables).
The Palace front really looks grand with the gate gilded, and there's even gold decorating the ornament along the roof !

CSI-type analysis will reveal secrets of the Versailles sleigh's painter.

The sides of the sleigh were evidently decorated with silver leaf having transparent, colored glazes of red, green and yellow over the silver.  This is all masked by a brown varnish.  How much can these colors be revealed without damaging them ? 
Samples tiny as a pinhead were examined under the microscope under visible light, and under different types of UV light yielding fluorescence (above, a sample from the side of the sleigh).  Layers invisible in normal light suddenly appear (I thank Jan Hobot of Cardiff University School of Medicine and the Centre of Biotechnology staff for use of their fluorescence microscope). Having travelled with me from France to Wales, this and other samples are now in Boston.  There, scientists Richard Newman and Michelle Derrick of the Boston Museum of Fine Arts will use scanning electron microscopy and micro-spectroscopy to reveal technical secrets of the artist working at Versailles in the 1730s, and those of an early restorer (made of King Louis XV, the sleigh was likely restored for Louis XVI).

The Entire Box of Chocolates

"I know it's wrong, but sometimes eating the entire box is the only reasonable response" (Marie Antoinette's ghost in my ear).  After 19 days I have one 2-Day Air UPS box.  When will I have the other box of my equipment ?
