Great piece of Olive wood...!
Excuse my ignorance but, what does WSSI stands for...???
Very good close ups there, and as always they are great to show everything, even the stuff we can't see with the open eye, and that brings me to the next question, what that white stuff, stuck in the wood porous...???
No CA you said so, I assume that is the sanding dust from the plastic stabilising material, right...???
Olive wood is well know to don't cast and stabilise very well due to the natural oils in the wood and while, stabilising this dense wood is not really a necessity but more an "option", for casting the issue is quite different.
One of the big advantages of having a stabilisation system is that, you can use it to prepare the Olive wood for both stabilisation and/or casting. The process has been tried long ago by a friend that has a stabilisation system and that I send him some Olive wood for him to process, as per my instructions.
The instructions were very simple indeed, put the wood in the stabilisation chamber, and cover it with acetone, proceed with the same steps as per stabilisation using a wood stabiliser solution. The result is simple, the acetone is forced into the wood cells, pushing/washing the wood oils out and "cleansing" the wood thoroughly, the wood is put to dry for a day in a well ventilated place, out of the sun and the wood is ready for stabilising or casting with the best results possible.
The only "warning" that I gave him was, "keep the wood well away from any open flames...!"
I done this to test the efficiency of the process to remove the wood oils that were playing havoc with my PR casting, and while I didn't have the proper stabilisation stuff then, I now have and I will be doing that myself...!
The only advantage I see to stabilise a wood like the Olive wood, is to allow the wood to be shown without any additional coating that will be always affected by the wood oils, sooner or later, unless left "on naturel..!" but that allow the wood to get dirty with time, when being stabilised like the sample from this OP, the wood can keep that natural wood look and feeling and be sealed of any dirt or scratches...!
Something to consider, definitely...!
