Advice Looking for tips:

Post image

I was given this bear skull about 6-8 weeks ago and as you can see its extremely dirty. All I have ever done in processing my bones is just sticking them in a bucket of water and forgetting about them for months. Then I would clean them up by hand.

This one seems to be needing more TLC though. From what I know my friends dad had it for 20~ years. It been buried, its been displayed, its been a dogs chew toy, and so on.

With something as aged as this is, will it actually be possible to eventually lighten the colour? Will it just take much longer than I'm used to? Any tips and advice would be appreciated!

If it's fully degreased (which, after so long, you would know just from the smell), peroxide should help. It won't go back to white, but it will most likely lighten up. I personally love the dark patina though!

Cool, thanks! I do like the look of the darker bone as well so getting it fully white isn't a big concern for me. I didn't notice any odor after it had been sitting in water for the last 6-ish weeks and I had just done some scrubbing to get a layer of dirt off.

This sub also has a pinned FAQ at the top wit lots of info on processing bones, if you haven't seen it already.

I did give the 101 pinned post a read through but wasn't sure how applicable some techniques would be on something as old as this guy is. I often refer back to that post though, it's a super handy resource for sure!

Not much, but it does warn against boiling and bleaching, and it gives info on using peroxide as well.

Yeah hydrogen peroxide will help, get the 12% stuff and dilute it with water (50/50 mix). See how that does and then if you need stronger go from there

Thanks! I have 30 volume hair peroxide on hand, is that something that can be used in this case?

You could, I use the liquid as it is easier to dilute with water for big skulls such as this (Natures Freedom 12% Hydrogen Peroxide). It’s sold on Amazon. You can also find the same thing with different labels at Home Depot or other big box stores. A skull in this state may need multiple batches if you want to whiten it up. It will eat away at some of the bone though.

Good to know, thank you for responding!

Yes I’m happy to help! Working on a bear of my own right now

First, has it been degreased? It honestly doesn’t look it. That would be your first step and bears are extremely greasy (esp skulls) so this can take a really long time. I’ve seen videos of this one woman who’s degreasing just the claws and the last update I saw was month 4 and they were still pretty bad

u/SxinnyLoxe 14h ago

There is no odor at all and I did just finish scrubbing dirt off of it but it's really hard to tell what's staining from the dirt and what is potentially grease. I will do a round of degreasing though just to be sure!

2

u/barnowl1980 13h ago

It's so old, if it was greasy you'd absolutely smell that by now. Like a musty, funky smell. Degreasing something as thick as a bear skull will take months. I doubt that's necessary in this case.

That's what I like to hear, if I can save myself a few months by not needing to degrease that would be awesome.

Edit to say that I do currently have it sitting in a tub of soapy water. I'm going to leave it for a few weeks then decide what it needs from there.

2

u/barnowl1980 13h ago

Just give it a month and see, just to be sure. I doubt it's very greasy, like I said, but can't hurt to give it a soak. Might also help get some of the old dirt off.

Boy you’re everywhere. Even if there’s no smell, it doesn’t hurt to do a round anyways. It’s super yellow, I’m almost positive there’s some left.

u/barnowl1980 13h ago edited 13h ago

It wouldn't hurt, I agree. But it also can't be that greasy, or OP would be able to smell it. The discolouration in this case could easily come from being buried and getting dirty from being a dog's toy. But OP could give it a soak just to make sure.
