H all,

it would be appreciated if anyone have proper prime for this blue star.

kno3-50

cuco3-25

pvc-20

dextrin-5

to increase colour depth I have just balanced the kno3,pvc,cuco3 ratio in composition...found in this forum....I use nano3 prime...i heard that PVC produces hydrogen chloride gas. It also works well in combination with magnesium, where the HCl gas reacts with the metal oxides in the colored flame to improve the color.

Addition of 5% coated mg will washes out the colour..??

While this prime is widely used for some hard to light stars, it too should have a BP prime over the top of it to maximize the fire potential though I use this alone on all of my non-AP stars.

 

Fence-post prime

Eugene Yurek

 

Potassium Nitrate 65

Charcoal Airfloat 12

Sulfur 10

Diatomaceous Earth 5

Silicon, 325 mesh 5

Charcoal, spruce, ball milled 3

 

Tare: Total: 100%

Afraid not. You need something that will dry or solidify around the metal granules to prevent corrosion or attack. Linseed oil polymerizes, and paraffin wax is a solid. Dichromate and other chemical treatments work by strengthening the surface oxide layer. Castor oil will remain liquid. While it may help, it will not provide a very durable or extended protection. I guess if you saponified it, it would become solid. Sodium Ricinoleate is known to be an extremely hard soap.
