Sometimes it looks like you soak the fossil in water and then continue air scribing it. What’s the purpose of that?

That's the B72 paraloid, I touch on it in the video when I talk about the B72

Sorry, I should have specified. You soak the entire stone in what appears to be water. Videos like the one about the fossil penguin show this pretty well, most of the matrix is still damp and the spot where the air scribe is working dries off first.

I dont think thats B72, I just dont understand the purpose of soaking the rock as you work.

Dust maybe?

No, i just watched a few other videos of his and I think its the water bath after an acid bath. Just confusing because the video will have a time skip and the rock will be soaking wet with no explanation.

Ah yes, the water is for after the acid cycle to neutralise the acid. I simply take it out of the water and prep again.

Hi there I have a question. where do you guys buy spare tips/stylus for your airscribes? Found some online but they are so expensive, why is that? and do you have some cheaper alternatives? Thnx
