Am building a Mission style coffee table from white oak and decided to fume it with ammonia following the approach in Chris Gochnour’s FWW 282 article. I ended up with somewhat uneven results and am not sure why. All the wood went through the planer then was sanded with 120 and 180 grit. I then dampened the wood to raise the grain and sanded again with 220 grit. I built a tight chamber similar to the article and dry assembled the table before putting it in the chamber with the ammonia. I could not get anything stronger than household ammonia but, based on other articles, expected to just have to wait longer. In the attached photo (after 96 hours) you can see an apron, which has turned out fine, beside a leg which seems to have reacted unevenly with the ammonia. Looking at the top of the leg I cannot see anything in the grain that would indicate heartwood/sapwood or any other variation. Am not sure what happened, and more importantly, what to do next?
