I’m wondering if anyone has experience preping stickleback fishes from a dolomite matrix. Obviously it is extremely soft and the preservation is decent but can literally be rubbed away with a breath. Will PVA stabilize dolomite or will it just melt at the introduction of any liquid? A friend gave me a piece to check out and I’d like to stabilize it. Any help appreciated. I can add pics tomorrow if needed.
thanks
Jeff
