I am in the process of completing an arts & crafts table made of QSWO. I have already decided I would like to ammonia-fume the piece, and it’s the first time I have attempted this process. (I have procured some higher strength ammonia from a blueprint supply house, and have invested in the proper 3M respirator filters and swim goggles. I appreciate the hazards involved.)
My question is regarding the finishing steps to follow after the fuming is completed. Unless someone has a different suggestion, I am considering the following steps:
fuming → BLO → Van Dyke Brown glaze → Target water-based shellac via HVLP → Target water-based lacquer via HVLP
I read that the BLO is the “magic” step to bring out the darkening imparted by ammonia. Apparently the oak initially comes out kind of greyish, but the oil shows the true darkening and more reddish/brown result.
Using the Van Dyke Brown glaze is adopted from another arts/crafts finish I used before, where a dye is first applied and dried, then the glaze is applied and wiped off immediately. It acted to further darken the finish and sit in the grain pores where the dye hadn’t penetrated. I may/may not do this after some fume experimenting, especially as the glaze I have is water-based and I don’t know how this will play with the BLO.
The Target shellac is mainly for a barrier coat between the BLO and water-based lacquer, and to impart some more redness.
Does anyone have any feedback or recommendations?
