Could anyone tell me what size stars I would use for a 4" mortar?

Around 3 3/4" would do it for a comet. A 1/2" hole down the middle and a disk glued to one end for the lift to push against, all wrapped up in a kraft bag closed with two clove hitches with a length of piped match leader and the lift.

Eep. sorry. ment to say shell

[alany]

I'd start with 3/8" to 1/2", depends on the composition, chlorates burn fast, AP burns really slow with others somewhere in the middle.

The granite effect is a subtle one that is easily lost in shells.
When they are high or washed out by flash bursts or used with a background of other shells, granite busts come off looking like a plain charcoal star.
I have to recommend mines. In this manner the stars allow you to appreciate their short life, soft noise, and cute outward spray of sparks; all unnoticeable from 300 feet in the air.
