The zircote you are seeing is the end result of dry wood used by experienced woodworkers. From another perspective, zircote is a pain in the butt to dry and sell. Zircote 8/4 almost exclusively has to be air dried, kiln drying will reduce your pile in half. Air drying is a nasty job also, one must dry it slowly, using tyvek or some sort of barrier to slow the drying process. We have thrown away more zircote than almost any other wood, macassar is right up there with it. Zircote has hit a roadblock in Mexico also, because of the drug trafficing. The sawmills are being threatened constantly. It is almost a smuggling operation to get zircote from the ground to the port without some sort of dangerous encounter. This translates into high pricing for the logs. One fellow buyer of Zircote logs in St Louis Mo has quit pursuing logs because of the dangerous nature of aquiring them. My 2cents. Leftyfred
