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?
