As the extract says above Jellutong can cause some irritation to the skin. After working two weeks with it I have found the backs of my hands and fingers have become slightly irritated and itchy from the saw dust when carving. Washing my hands regularly and keeping them moisturized have now stop any irritation after working.
My personal views on Jellutong are at first I was just really glad I had found a local source of good carving wood after failing to find Lime. I'm It is a real joy to carve in and I believe I wouldn't have gotten the same results have not used in traditional wood and craft skills. But after reading up on Jellutong and its environment effects it leaves me with mixed feelings. I maybe low on morals but I want to use the best materials possible to bring my personal models to their full potential regardless of where they come from or how they are made. From a clients point of view though they may feel differently about the issues and I obviously would respect that and go about the project in a different manager.
