Thanks for you response and clarification of your methods Georgia. I agree with both you and Alan that museum workers should certainly be made aware of these findings. Considering the condition of these blades prudence would be wise even if any danger is unlikely. I am glad these clarification have been made because your original statement that "it (arsenic) is certainly present in sufficient amounts to cause adverse health effects" seemed unnecessarily alarmist to this group of collectors who in all probability maintain their collections in much better condition than the museum seems to do. You would find no surface residue on the keris in my collection (and certainly no white powdery substance) and though there may be something hiding in the crevaces of the gonjo it seems highly unlikely that i am at risk of ingesting any of the substance or even absorbing it through the skin. I hope you understand that i also am not discounting your research which is indeed very interesting and valuable, but i am trying to put this information into perspective for the audience you are addressing on this forum. Of course, if there are any paranoid collectors out there who want to now get rid of their collection cheap i would be happy to help them out.
I look foward to hearing more about your findings when your project is completed.
