Re Reply # 63: What a horror to be dreaded by every collector who displays their collection/s ! I continually examine my cases (with mostly Russian Imperial and other early ceramics), yet things DO happen. I once had an English dessert dish crack badly, IMO, because of the internal stress caused by the interior lighting of the case and the apparent clash of the room's air-conditioning. There was no vibration or friction from any near item, but although the pieces of the dish did not separate, the crack totally ruined the piece. No other items were affected.
Over-loading a glass shelf can obviously cause a shelf to collapse upon another. If memory serves me correctly, the Duchess of Windsor lost more than several examples of English royal 18th century wine glasses in such an instance.
However, it would seem that in this case, over-loading (beyond the tensile strength of the glass shelf) and improper temperature contrasts were NOT the apparent fault at first glance. There was probably a hidden flaw within the glass that caused it to shatter, OR alternatively, a support/s of the shelf failed.
Regardless, the "Buddha" with the articulated hands, head and tounge (the style sometimes referred to as a "nodder") is a very well-known Faberge/Michael Perchin piece. It is shown in A. Kenneth Snowman's, "The Art of Carl Faberge" 2nd Ediition, as #277, facing page 65, and described as "Jadite 'Magot' with gold cuffs, and belt enamelled opalescent white, the latter studded with rubies and rose diamonds. Ruby and rose diamond eyes and a carved ruby tounge. The head and hands are so balanced that the slightest movement sets them in motion. Height: 12 inches. Signed: M. П."
I can see how the figure described above could suffer damage because of/to the free-floating parts, but for the potentially non-articulated( ? --the article DOES say that the head became "unhinged") second piece to be broken as it is, it must have sustained/absorbed a rather sharp blow, as jadite ranks rather high on the scale of hardness. Perhaps the head was hinged to act as a sort of container cover. I am just not familiar with this second piece. AP.
