In February 14, 2009 I made a project consisting of a pine cone, painted to look like a rose, on a padauk base finished with tung oil, and a glass dome. Over this last weekend I saw this project again and saw that the glass dome had a film over the inside. I made another one of these about four years prior with a polyurethane varnished Oak base and it is still perfectly clear.
Considering that the pine cone was from the same tree, the same paint was used on the pine cone and the glass dome is glass. The only variables are the padauk versus oak and the tung oil versus the polyurethane varnish.
I theorize that the tung oil is caused this and wondering if anyone else ever seen this phenomenon or had any other insight as to what may have caused this film.
