Title: How long can sand roses last?
Post by: jack_ on 19/03/2019 10:46:08

Gaelle has been adventuring and sent us this question:

We went out in the desert to look for sand roses and I don't know much about them. We found a fair few, but some of them are crumbling...do they last? How long? How can I keep them intact?

I seem to have read that they are made from Gypsum or Baryte and that the gypsum ones tend to be more fragile.

Do you know anything about them?

The story makes me very confused. You make it clear

It might be worth looking here, if you have not done so already.

Given that they are "geology", how old is a desert rose when you find it?
