When you state 'spherical aluminium' what are you referring to? Probably being very stupid here but I'm stumped!

Flake is produced by some variation of mechanical rolling/pounding. Spherical is produced by blasting a stream of molten metal with a jet of air to create very fine droplets - also sometimes referred to as 'atomised'. Flake generally looks silvery, spherical more greyish. They are not always interchangeable in compositions, as they react differently. Spherical is more difficult to ignite.

Breathing apparatus, proper sealed masks for any flake. It wants to be airborne. It lives to fly around in the air.

Interesting made up fact: planes are probably built out of flake aluminium so they can fly. It's Virgin Al actually, that sounds far sexier.

Hey guys (newb alert) I want to purchase a star roller from pyro gear and was wondering what would be the easiest star to make from the list above as a first try. Also would 2mm dia lead shot suffice as cores? Thanks in advance!

Welcome to the forum:
Lead shot can be used but if this is going to be your first time rolling I would suggest starting with mustard seeds as there a little more forgiving.

Regarding what composition to roll I would suggest avoiding any heavy charcoal based stars until you get some experience under your belt, the Veline comp’s are good starting point but we have developed some formulas using PVB that are a dream to roll, I can supply some PVB for free when you purchase you roller.

Am I right in saying that pvb used in compositions helps with binding the mix and also makes a brighter burning star , and less need of priming them
Thanks

PVB will actually tend to diminish the flame envelope, some... so no -- not 'brighter'. But it will distinctly improve the colors of those things needing the compound.

It IS a good binder!

I’ve also noticed that specific charcoal is used for different compositions, I have access to willow trees not a problem ,
Pine charcoal obviously from a pine tree , is conifer wood also in the same class as a pine tree ? Or is it classed as its own type , has anyone had experience with conifer ?
Thanks chris

Pine is but one subcategory of the all inclusive "conifer." "Evergreen" is not quite as inclusive - the Tamarack tree, aka larch, is a conifer but sheds its needles in the winter. Often it's described as deciduous conifer.

Yes. We have the same with the Florida Bald Cypress. It is a conifer, but is deciduous.
