"gluing" Driftwood To Natural Stone

I have a piece of wood that likely won't ever sink on its own and am thinking of sticking it to a rock with clear silicone. Will that work? I'm guessing so but just want to fly it by the board before I make another mistake.
Oh, and what about sticking two pieces of wood together? Silicone can do this, right?

Thanks!

 

I glued my driftwood to a tile using silicone. It worked great.
I kept it in a tub for a month and it did waterlog, but not completely.
Make sure you use aquarium-safe silicone and you'll be alright.

 

I boil my new driftwood for a few hours before putting it in the tank. It sinks right away.

I wish mine did that. I kept boiling it, I even drilled holes to try and get water to the core, but it still floated after a month.

Pescado_Verde, try Dave's suggestion is you haven't done it. You can also try drilling small holes in an area that won't be visible. If that fails, then you can glue it.

What kind of wood is it?

Wow really? You that must have been a really hard wood. I use mopanI in all my tanks. Seems to sink fast after boiling.

Yeah, I believe it was the kind of wood.
I just loved the shape so I really didn't want to change it and went for the tile method

 

I have a piece of drift wood that refuses to water log too. I have done everything I can to get it to sink but it refuses so I finally tied a rock to it to hold it down. I will have to rework the rock though because the wood isn't sitting the way I want it to. I will let it sit the way it is for another month or so and if when I remove the rock it still floats I will attempt the silicone method of attaching it to a rock.

 

The wood that I have is cedar and it's just not that dense. It's very old and very weathered, I've boiled it long and hard and still it wants to float a bit. I'm not worried about tannins or anything like that, I got the wood from a friends rock garden where it had been for a decade or so.

It is long dead and it won't rot. We use cedar here in Texas for fence posts because it doesn't rot. I've seen fence posts that were 50 years old and they turn a wonderful silver color and split from drying for so long in the sun and weather, which is what this piece of wood looks like.

I just wasn't sure if silicone would hold these two materials together. Oh, and as I added above, I may "glue" another smaller piece to this larger one to create a bit larger piece. I was pretty sure that silicone would stick this stuff together, just wasn't for certain.

I have also turned this piece about every way possible and looked at it from a hundred different angles just to be sure that when I do stick a rock to it that it's not something I'm going to want to change later on. Thanks for all of the replies! Maybe after I get this thing put together I'll post some pics of it before and after.

This is my only real worry with attaching it to an anchor; that I won't like it or will second guess myself. But my tank is still in the build stage and I've flipped this piece of wood every which way and pondered on it for hours and I THINK I've got it the way that I want it. Crossing my fingers!
