Gringard magnesium is very coarse. It could probably be approximated by thin Mg machining swarf. It looks like little strips of foil, maybe 1-1.5mm across, and between 3 and 6mm long. Thats the stuff we usually use anyway.

I did have a question. Am I correct to assume that you need the CMC free-base, and not the sodium salt of it?

Hi Toivo - thanks for the formulas - do you know the approximate size of the magnesium particles please?

Yes I have: about 0,5 to 1 mm, thickness about 0,2 to 0,5 mm, refrerences: ECKART-Werke ECKA MF 0,5 - 1 mm = LNR 17
as laboratory chemical true Grignard-Magnesium.

Greetings

Again Magnesium 0, 5 to 1 mm, about 0,2 to 0,5 mm thickness, like ECKART-Werke ECKA MF 0,5 to 1 mm = LNR 17.

Its commun Tylose (sodium salt).

I would have thought the sodium presence from the CMC would kill any color that might be produced. Then again, I'm unsure just how much sodium CMC contains.

CMC doesn't have any sodium in the molecule. There is a sodium salt of CMC though, simply called "sodium CMC" you may confuse CMC with.
Wall paper glue (metylan) is pure CMC.

Dear Friends:

Finally: anyone tried it ? At least the white one ?
Cannot be so complicated !

When I still was an amateur
and not a professional, like today, I was happy with these
formulas for many years.

Tovio, I'm interested in these formulas, but do not have any Mg of the type mentioned.

I do have some 0.5mm spheroidal Mg - do you think this will work?

Simply try it, without any guarantee that it will work.

Shall do. I shall report back findings!

Any one with a formula for purple strobe stars?
