Angelique is superior to teak and white oak, when either green or air dry, 
in all properties except tension perpendicular to the grain, in which it is 
surpassed by both. 
Mechanical tests made on the three forms of angelique show no significant 
differences. 
Machining Properties 
Sawing and other machining properties vary among the different forms of 
angelique and are reportedly due to differences in density, moisture content, 
and silica content. Angelique rouge is reported to be the easiest to saw and 
the blanc form the most difficult; the latter also tends to produce lumber 
with fuzzy surfaces. Sawing is least difficult when the wood is in the green 
condition, although considerable dulling of the saw does occur. After the 
wood is thoroughly air dried or kiln dried, it can be worked effectively only 
with carbide-tipped tools. A planer cutting angle of 15° is said to be suit- 
able for working this species. 
The wood finishes smoothly and is moderately easy to glue. 
Seasoning 
Duke University found that h/k, 6/4, and 8/4 stock air seasoned well during 
the period of 2 months in which the average temperature was 6l° F. and the 
average relative humidity was 58 percent. During this period green boards of 
the above thicknesses, which varied between 67 and 92 percent moisture content, 
were dried to a 13 to 23 percent range with only mild end checking and with 
slight cup in the unrestrained boards on the top of the pile. Air-dried k/k 
stock was kiln dried to 8 percent without degrade on a normal hardwood schedule. 
However, it was found necessary to use a very mild schedule for kiln drying 
green stock to avoid collapse. 
One of the producers of angelique has reported successful use of a kiln schedule 
given in table 3 for green h/k flooring stock. The drying time is 21 to 2k 
days. The temperature during the initial steaming is high enough to cause col- 
lapse in collapse -prone materials, so caution should be used if this procedure 
is followed. The producer reported that the cooling-off period was necessary 
to avoid bowing and crooking when the material was manufactured into flooring. 
Perhaps a good conditioning treatment, such as is given in Forest Products 
Laboratory Eeport 1791 (3)> would achieve the same result.
