I don't know why more members are not playing maybe it's to do with holidays etc. I find it really good fun doing a little detective work and learning about different woods at the same time. Of course I've already got the answer to your 4th question and so I won't post it here.
Btw the new game has served as a reminder to claim my prize from last month's game.

Yeah, now you're talking...!

Yes, that was one of the few Golden Wattles I processed in these last 11 years, and yes, that was a very interesting tree story that I had to tell, again, historical..? not really, was one of many trees planted in that car park all those years back, it had absolutely no value to anyone local, not even for firewood up here, unless is Red Gum, people won't care however, and as I said, it was one of the trees that I manage to get the full story of which I got involved in the end and still today, some people are enjoying the blanks/wood that came from it.

There has been a couple more of these trees I cut/salvaged since that one, every tree is slightly different, mostly due to age, either live time and/or since dead and in contact with moist soil, fungi works very fast on it...!

So, in fact, Golden Wattle "old" wood may not have much to do with the age/time lived of the tree but, how long the tree has been dead for and how much decay it has.

I have a good example for you that I sliced up yesterday at the wood storage paddock and in between showers of rains (has been for a few days).

These are a couple of large logs (for a Golden Wattle tree) that I got from the firewood processing plant a few months back, the tree was live when cut even though it was over 50 years old from it growth, I know that is was dump there not long before I found it so, I got some of the biggest logs to process at later time however, I had a fellow that asked me for some decent slab sizes of the Golden Wattle with the vivid reds in it and I knew that these logs were ideal to get what he wanted but before I processed it, I cut a log into 2 and then sliced one log so that I could take pics for him to see.

These are 2 of the pics I sent him, the wood is not dry but it won't take long to dry to workable stages, this wood is fairly soft and therefore dries fast, it helps if you keep it under cover and not in the rain as I have, however, I brought home the 2 halves, one was processed for this fellow and the other half was cut into 2 square blanks and put to dry.

I also appreciate that you haven't mention the answer of question 4, it gives the chance to someone else, thank you...!

Cheers
George

G'day mate,

You need to clarify the answers 2 and 3...!

Hi,

Could you please answer the questions 1 to 4 in your own words...?

Thank you.

True, that and rocks, steel cable, pushbikes, etc. however, these are not "natural" from the wood, the "other stuff" is..?

Down the mountain you go...!

2. It's old because it seems to have oxidized to a darker color, like a lot of the rosewood family does. Fresh cut seems to be brighter & have more vivid colors.
3. I can see it has more brown than red colors in the pics shown.

I believe the darkening of the wood is caused by exposure to UV rays from the Sun.
A lot of the red woods like Bloodwood, Redheart, etc. darken with Sun exposure.

I think "old" and "aged" are being used interchangeably here. Just because it's aged doesn't necessarily mean it's an "Old" tree to begin with.
I hope that makes sense to you.

1. Golden Wattle
2. Old
3. Age of tree and/or time since cutting (I assume this is essentially a form of spalting)
4. Well, I said silica, but now I am questioning everything. I tried to do some research to find supporting information and found that common wisdom supports the claim but scientific literature contradicts (or at least does not support). This study https://eurekamag.com/pdf.php?pdf=004159366 is one example. Also, this article Sand in wood? Fact or Fiction? disagrees with silica being the primary contributor. That said, most of the common wisdom out there says that silica and other mineral content is the main cause of tool dulling or blunting. Unfortunately there isn't much funding for this type of research, just finding silica content of different woods is more difficult than I thought it would be. So I guess my answer is "silica?".
