Hi guys I recently started rolling stars and I thought of making some color changing ones, the size of shells I'll be making is 2.5" and 3",for color changing stars I was thinking of using either a 1/8" or a 3/16" star as a core and then apply the second layer until the star grows up to 1/4",and for glitter to color stars I was thinking using a 3/16" core and then grow the stars up to 5/16", so what do you think, what size of core should I be using for each of the effects I want to make? color change and glitter to color

I feel like 1/8" is too small for a color core. I like 6/32 or 7/32 or even 1/4 better.

 

In my opinion for both types of star you should start with 1/4" and roll to size 3/8" and then adjust diameters from there.

Depends on the type of break you want, but I don't think 3/8" is too big if you are using a tailed star composition.

 

Color changers aren't something you will get perfect from the start, test test test!

That's the first thing on my list... test, test, test, small batches so that I don't waste chems like an idiot, thanks for the advice

For core sizes in firework stars, I use White Millet bird seed. A year ago, I bought a 50 pound bag of it, because I knew I was going to be busy with firework projects, which is why I'm here. The White Millet I use is 1/16 of an inch in diameter. Before I roll a batch of stars, I soak the White Millet in a cup of denatured alcohol for 30 minutes to ensure that it is wet.
