So little time these days with all the work at the university. But I finally settled for a while to build a wooden clamp for test tubes to make a first measurement of the temperature at which xylindein, the pigment produced by Chlorociboriae, permanently loses its color.
As you all know, sanding wood leads to quite high temperatures at the surface, and I had previously noticed that xylindein was destroyed when bandsawing stained wood with a freakin’ dull blade from hell. As I couldn’t find any reference to said temperature, well I will figure it out myself. This will be a first crappy measure just to check the temperature range (which I expect to be in the 50-300°C at least).
Why bother? Well, as I already said, sanding or sawing xylindein-stained wood can lead to its permanent discoloration, which sucks.
So the first step to actually measure that destroying temp, is to have a test tube securely clamped in an insulating material to be able to gradually increase its temperature while monitoring the color. Then make a chart of the measurements, graph the heck of it, and determine the decaying function blablabla, to finally get the number of the beast. For now, here is building a test tube wooden clamp with a scrap of palletwood (pine actually) with the detail pictures.
And uh, I can’t resist the envy to also post it for Martin’s latest contest :D
