how many stars in a shell

[pyrobob]

I was just wondering (sorry if this is somewhere...i didn't see it anywhere, and i didn't know what to search for) how many about 3/8" stars go in a 3"...its my first time making a shell, and I wanted to know how many stars to make

 

(I want to do as small of a batch possible)

 

thanks,

A calculator says 116. For a ball shell, it will take roughly 100g, maybe 150g for a can shell. I'd say make 200g to be safe. It will give a bit to for testing, and if some stars don't turn out as well.

may some useful info by shimizu for chrysanthemum shells:

 

size of shell / size of main star / number of main star / burst

 

3" / 9mm / 150 / 35g

4" / 12mm / 170 / ????

6" / 15mm / 200 / 270g

8" / 19mm / 260 / 770g

9mm is a little smaller than 3/8".
