« Part 13: Pushing the studies on Chlorociboria to their ultimate goal Part 14 of Spalters Inc. series no next part

Hi all,

Long time since the last installment.

So, after using most of my time this year as a teacher, I finally managed to get back to the study with the folks at the C2RMF. Good and bad news : xylindein, the green stain produced by Chlorociboria, doesn’t really get on well with most finishes. When it’s still in its “raw” form, inside the mycelium of the fungus across the wood fibers, it’s less picky but still some finishes won’t do the cut and will fade it with no possibility of a return.

Why does it matter? Well, when you’re dealing with an historical piece of furniture, the last thing you want is your new varnish to destroy its color. Even for contemporary work, given the work that it takes to cut the veneers and assemble a marquetry, it would be a shame if the finish destroyed the color after a few weeks/months/years.
If you work with green-spalted wood, that is.

Now that the study is done (but not yet published) I can give you all a hint : stay away from petroleum wax, it totally destroys the xylindein in a matter of weeks! Beeswax doesn’t cut it a lot more either. Shellac is okay as long as you use the dewaxed blonde version, preferably bleached. More next time!

Cheers

The obvious answer is for you to make your own compatible finish now. Sodathane!

Cool. This is very interesting for me. I’m just waiting for the article. As I know, craftsmen who made the Cheb relief intarsia, they used just animal glue as a surface treatment and in some cases wax on it and later in history people put the shellac also. In most cases it’s still green.

Thanks for the update Thomas. Would you be able to post a link to the article when it is published?

Thomas, Nice to see you post again. It’s been a long time for me too. I just remembered that my Daughter is in France as I write this.

@Chris: whoa, dude, gotta love that name, hahaha!
@Dominik: hey I didn’t know that, do you have any studies on that matter? Shellac disturbs xylindein on the long run with exposure to light, as my exteded study showed.
@Paul: that will be the next step, it was an internship report, but I sure will.
@Ken: been ages for sure, this first year as a teacher was really painstaking, not because of the teaching but because of the corresponding (useless) diploma.

You’ll see more of me these holidays, I’ve started building the bandsaw sawmill last time I was at the parents’, this summer I might be able to really get a lot done on it, for now I have the cutting head welded, which was the difficult starting point: teaching myself how to stick weld, with help of all the Youtubers who do just that!

Well on the topic of xylindein I still have a few surprises under my sleeve!
