  • Crotch mahogany wood has a strong red base color.
This wood was taken from a special mahogany wood, since that he has a red base color like other mahogany wood. The red color in the crotch mahogany is very strong, stronger than the red color on the regular mahogany wood. It makes the color selection for this wood is limited. Most of the crotch mahogany is finished in red or red brown color.  We may be able to eliminate this red color using the green stain; but it will need very thick stain to kill the existing red color. Use of stain that too thick can cover and block the beauty of its wood grain, the main strength of this wood.
For some wood furniture product which needs to be color without any red color or light color, then we have to bleach this wood. The bleaching process for crotch mahogany requires a very strong bleaching material, and sometimes it has to be repeated several times to get rid of his strong red color. Bleaching for this wood is rather risky because it will increase the possibility of the cracking problem in this wood.
  • Cracks in the crotch mahogany
Crotch mahogany wood made from wood branches with the cutting along with the branch direction. Naturally this wood part has high movement. This condition make the crotch mahogany is easy to get crack. The crack is the biggest problem for this wood. These cracks can be found at the unfinished conditions, in the finishing process or when the furniture was already finished and used. 




Glue sizing for crotch mahogany veneer
 
One way to reduce the occurrence of cracks in the wood is the gluing process and glue size. The gluing for the crotch mahogany veneer should be done carefully. The factors that influence the quality of gluing such as moisture content of the veneer and the core should be matched. The type of glue and the gluing process must be maintained and cared for to reduce the problem at this veneer.
To reduce the crack problem, some furniture factories do glue size for the veneer. Glue size for this veneer is slightly different with glue size for soft wood that is purposed to reduce the wood fibers on the wood. Glue size for crotch mahogany veneer is done to reduce the occurrence of cracks in this veneer. Since that it done with the stronger glue, the glue that usually used is a thermosetting adhesive that can tight the wood and close the pores and grains of wood and thus the surface does not absorb the water from his environment. Glue is applied on the veneer surface and then followed with a good sanding to produce a even and smooth surface.
The thick glue application of course will reduce the absorption stain on finishing process thereon. This could influence the beauty of his wood grain character, but since crotch mahogany has very strong grain character, we still can perform the interesting appearance with this method. The glue size is could be best choice that must be taken to reduce the risk of rupture.
