You know the ideal proportion ARABIC GUM / WATER

(Spray; for binder final layer BP stars) of Gum arabic mixed with water?

[alany]

Kentish says 75 grams per litre, but Kyle (of passfire fame) says 27 grams per litre is sufficent.

You know the ideal proportion  ARABIC GUM / WATER

(Spray; for binder final layer BP stars) of Gum arabic mixed with water?

I have heard of 4%, 7%, and 10% being used, but I can't remember which formulas the different percentages came from.

Also, you might want to consider this:

"Gum arabic is acidic due to its high content of glucuronic acids, although
these generally form salts with alkali or alkaline earth metals.

By using a freshly boiled water addition much of the bacterial action can be
hindered.

Gum arabic is a very good binder if pure water is used as a solvent."

I've read that prepared Gum Arabic solution should be used on the day of production, to stop it from beginning to ferment, but I have no direct experience with making it. I have only used pre-prepared stuff, which seems to store well - I have a pot of it sitting on my shelf.

You can add a little amount of ascorbic acid to the solution, so it won?t ferment over the time.

Why Is very difficult to dissolve the ARABIC GUM, in water ?

One day or two to be dissolved, completely ?

The water must be "cool" or "hot", for it ?

Yet, I do not know the ideal proportion ARABIC GUM- WATER for "prime" with BP my stars rolling.

Please. I need to help.

Some type of reaction can exist, decomposition ? spontaneous combustion, to the contact the ascorbic acid (vitamin C) of strong oxidizers: as nitrates, perchlorates, clorine donors ? metallic powders?
