Cuttlefish bone uses

On Christmas day we went for our normal beach walk. I normally collect seaweed for the garden but this year it was so stormy, 40mph winds blowing onshore and blasting sand at us, that the seaweed had been washed away by the tide. Instead the beach was littered with cuttlefish bones, higher up near the dunes. I collected quite a lot because I thought I could make use of them but was wondering if anyone had any ideas that perhaps I hadn't considered.

Ps I don't have a budgie

 

Do you know any jewellery makers? I seem to remember they use them. For what, I don’t know.

 

I did a bit of research @Thevictorian and found that they can be ground up to produce a calcium rich powder which can be used in the garden, for example for calcium hungry crops like tomatoes, peppers, broccoli and cabbage. One video I looked at recommended soaking them in clean water then drying them out before grinding. Calcium can also be used to alter the pH of soil by reducing its acidity. No budgie? How about a pet parrot, parakeet, tortoise or snail?

 

I was left with cuttlefish when I lost my parrot and tortoises some years ago. The Great African Land Snails also made use of it. I finally used it up by making it into a powder to sprinkle on some of my GH edibles as @Plantminded suggests.

 

Cuttle bones are composed of mainly calcium carbonate and minerals etc including heavy metals ,such as strontium, lead,mercury etc in low concentrations.

 

Thanks everyone. My initial thoughts were to grind it up and use it like lime on our brassica's but we do have a decent amount of lime left, which we were given some time ago. My second thought was to grind and add it slowly to the worm bin as I now they need calcium. The last thought I had was to make some bone char with it when I do my next biochar burn. I think it may be the best use for it but I appreciate the ideas.

Not sure a parrot would help much, I got enough to keep a pterodactyl happy for awhile.

 

I believe they use it for molds when casting metal but I believe it also polishes metal quite well.
