I am new to this forum so in brief, I am an artist living in Jersey looking for some info on fuming oak. My wife and I have recently finished a small table in qtr sawn white oak. We built a small fuming chamber and fumed it overnight with some ammonia used to develop blueprints. We got wonderful results and have been inspired to try this process again. We are also curious about whether this would work on previously finished pieces, like those finished in tung oil? I will try to cull some more info from past posts and threads, but I look foward to hearing from anyone out there regarding this process.
