The image in the header was captured by taking a smooth cut piece of Chin Chan and placing it direcely on the scanner. This is not from a picture, it is a directly scanned image of the Chin Chan wood.

DALBERGIA - CHIN CHAN
From time to time we are fortunate to have access to a lumber type referred to as CHIN CHAN in Thailand. It is also spelled CHING CHAN and CHING CHUN. It is a Dalgergia genus, a very hard wood. The genus/species is Dalbergia Oliveri.
 This wood has a beautiful deep dark brown. Because of its hardness, it is a very long lasting wood for flooring applications. The Janka hardness factor for Chin Chan (dried) is over 3,000. This wood is so hard you MUST use power tools to work with it. Carbon tipped power saws are really a minimum requirement. Some tell us that, when sawing this wood, it is so hard that the action will throw sparks. The image on the right shows two pieces of Chin Chan. For perspective, each piece is cut at about 2 inches x 2 inches. The thickness is 17mm, about 2/3 of an inch. Both pieces are kiln dried and smooth cut. In addition, the piece on the right has a semi-glossy finish, the piece on the left has no finish. We ship our products with no finish. The finish has been applied to give you a better idea of the appearance after applying a finish in the event that you intend to do so.
 As stated above, this is a very hard, very heavy wood. As a small test, we took three pieces of wood, a light scrap wood, a piece of Padauk (a heavy wood) and a piece of Chin Chan. On the left you see a top view picture of a glass pan of water containing these three pieces of wood. The scrap wood is on the left, the Padauk in the middle and the Chin Chan on the right. However, it is not clear, from the top view, whether the pieces are floating or sinking. The picture on the right  provides a side view of the glass pan. With the side view it is clear that the scrap wood on the left of the picture is floating and the Chin Chan on the right of the picture has sunk to the bottom. The Padauk, in the middle, is partially sinking and partially floating. It is clear that the Chin Chan is, indeed, very heavy. In fact, if you intend to use nails or cleats in laying this flooring, you will need to prepare the Chin Chan by predrilling nail holes. If you try to do otherwise you will find that you cannot drive nails directly into this wood without preparation. If you are working with "green" chin chan, this is not as much of a problem as "green" Chin Chan has a hardness factor of about 2,200. But when dried, the hardness factor increases to 3,000. This provides tremendous durability but at a cost of dealing with some extra difficulties in the construction process. It is best to use carbon tipped power tools (or better) when preparing the Chin Chan for any application.
Because of the dark color, this wood is probably best used in areas with adequate lighting. It will require preparation.
We are fortunate to have a stock of this wood available as of 23 May 2004. This stock will probably be gone in a few weeks. We never know when we will have access to it again. If you are interested please contact us as soon as possible.
