Subject:Re: Zitan table - HELP NEEDED on restoration
Posted By: kirk Fri, May 31, 2013
Zitan, possible but unlikely. The confusion arising from zitan generics imported into China from mid 19th, in fact even earlier as ballast (Dutch East India co) species Pterocarpus melanoxlon - East & Southern Africa. (blackwood) Post suez Pterocarpus soyauxii - trade name African zitan, West Africa. Both very similar & easily confused, similar specific gravity; similar even under a microscope, but there are a handful of scientists on planet earth that can draw the distinction. Pterocarpus santalinus from the Himalayan foothills is the only species that should be called Zitan, but even this statement subject to some debate. Dalbergia benthamii & Pterocarpus dalbergiodes have both been classified as zitan & held @ Chi Sung Kung for exclusive use of some 16th/17thC emperor's furniture. Nonetheless, P.san is the species that prior to these 17thC generics exclusively referred to as Zitan, as is clear as a result of Chi Bao's 3rd C publication 'Gu jiu Zhu' (an explanation of ancient & modern things)
Distinguishing feature of the one true species that can be classified as Zitan is the distinctive shimmering figure. Similar in many ways to the back of a fiddle. There are various grades, & this refers to how prominent the figure is. Third grade the figure virtually non-extant, but if you look very carefully at the grain of the timber all over the piece, it will be there somewhere. If it's not there, don't call it Zitan.
Concerning the restoration:
first establish if you have zitan. If you do, leave it alone.
