Would everyone pitch in to create an "all there is to know" compendium about chatoyance? My understanding is that this what we sometimes observe when placing face and reverse sheets of veneer leaves side by side, as in a book match. One paragraph in Lincoln's "The Manual of Wood Veneering" suggested that this results when the pores of the wood are at an angle to the surface of the veneer. For example, pretend the pores are rising to the right, moving from the reverse to the face side of a leaf of veneer. Turn that leaf over and the pores will now rising to the left from the face side (now the bottom) to the reverse side (now the top). I've always assumed this effect explains the different look of the two sides of the book match in the attached example.

Presumably, burl doesn't show this effect because the pores are going in all directions, and most flat and quarter sliced veneer would have the pores more uniformly in line with the length of the veneer?

Are there certain figures more likely to show this effect? Certain species of wood? Would be nice to know when designing a veneering project.

Thanks.

Curly Maple can exhibit this feature.

As one moves relative to the doors on this entertainment armoire, they seem to "shimmer" in response.

First of all, nice work on that curly maple piece. Secondly, my biggest seller has been curly maple pen blanks. I used to to pull my hair out, trying to take photos of it, and finding some of the blanks look like they don't have any curl at all. I finally figured out that i need to take the pics at less of an angle or to aligh them up, so that they all show at the same angle. Curly koa is the worst, in my opinion.
