insutama Posted August 17, 2015 Share Posted August 17, 2015 so i made a sample batch of the veline magenta stars Potassium Perchlorate 0.530 Red Gum 0.090 Magnalium, 200-mesh 0.060 Strontium carbonate 0.070 Copper oxide, black 0.070 Parlon 0.140 Dextrin 0.040 Total i dont have any silicon or wood meal so im wondering what would work for a prime for these stars i pumped a small 10 gram batch and they seem to light pretty easy with a touch of a flame im just wondering what i could use to prime these with basic chemicals i have most the basics, kno3, kclo4, charcoal airfloat, magnesium, magnalium, and lots of other so please if anyone knows of a good prime that would work let me know thanks Link to comment Share on other sites More sharing options...
pyrojig Posted August 17, 2015 Share Posted August 17, 2015 You dont need the Si or wood meal. I use primes that are like Jopetes for color stars. Single-layer prime0.30 Potassium perchlorate0.38 Potassium nitrate0.14 charcoal, airfloat( soft wood)0.05 Red gum0.06 Sulfur0.09 Black iron oxide0.15 Magnalium, 63-micron, 230-mesh( 200-325 mesh works)0.05 Dextrin Most primes when heated up with a metal content will serve well for color star ignition . Outside that ( strobes and flitters need step priming and special primes to aid in ignition) Link to comment Share on other sites More sharing options...
insutama Posted August 17, 2015 Author Share Posted August 17, 2015 so i just screen mix this all together then wet my stars with water ? or could i use alcohol because of the red gum. then just roll my pumped star in a container with the screen mixed prime ? this is my first coloured stars i have made i really really like the purple colour this formula makes i just now want to get a solid prime. i wetted these stars with alcohol and pumped them with a 1/4" star pump Link to comment Share on other sites More sharing options...
Xtreme Pyro Posted August 17, 2015 Share Posted August 17, 2015 so i just screen mix this all together then wet my stars with water ? or could i use alcohol because of the red gum. then just roll my pumped star in a container with the screen mixed prime ? this is my first coloured stars i have made i really really like the purple colour this formula makes i just now want to get a solid prime. i wetted these stars with alcohol and pumped them with a 1/4" star pump Seeing the above prime includes dextrin, I would just bind with water. Best way I have found if you have a star roller is to use the toro method to apply the prime, I seem to get the best results doing it this way. Although it will work just fine using a spray bottle and a bowl with a round bottom and coat them by hand, as you stated in your post. Link to comment Share on other sites More sharing options...
insutama Posted August 17, 2015 Author Share Posted August 17, 2015 (edited) okay hey i was just looking at primes and the pinball prime seem pretty simple only needing 3 chems and it says its good for a hot prime it says to add 6% magnalium for hard to light stars im not too sure how hard these veline purple stars are to light all i know is they seem to take fire pretty easy when lighting them with a flame and thats with no prime at all so im guessing this pinball prime would work good has anyone had any luck with this ? Pinball Prime http://www.fireworking.com/sites/all/modules/print/icons/print_icon.gifPrinter-friendly version CATEGORIES: Primes Chemical Percent/Parts Amount Potassium Perchlorate 0.750 Charcoal (airfloat) 0.150 Red Gum 0.100 Total Edited August 17, 2015 by insutama Link to comment Share on other sites More sharing options...
schroedinger Posted August 17, 2015 Share Posted August 17, 2015 Pinball worked good for me but meal + 5% Dark Al or fine MgAl where good too. For priming either use a brush and brush on the prime or dip them into a prime slurry maybe followed by a dip into ffg ? You only got 10 g). Or slurry prime them inside the shell.

insutama Posted August 17, 2015 Author Share Posted August 17, 2015 i just tried hand rolling the stars and there drying now but ya it doesn't look like the best coat so after they dry ill try putting a other coat on them the way you said to with a brush see if i can get a thicker coat of prime on thanks guys Link to comment Share on other sites More sharing options...
braddsn Posted August 17, 2015 Share Posted August 17, 2015 For these, 1.5 - 2mm of bp meal + dex will work fine. Or, .5mm monocapa will also do it. Link to comment Share on other sites More sharing options...
insutama Posted August 18, 2015 Author Share Posted August 18, 2015 did you use ballmilled meal or just screen mixed ? Link to comment Share on other sites More sharing options...
insutama Posted August 18, 2015 Author Share Posted August 18, 2015 also whats the best way to coat these little pumped stars i tried rolling them and it didnt really get a even coat and the coating was very crumbly so i tried dipped them in alcohol then in prime then back in alcohol then i put them on my screen to dry it all look good but then when they dried and i tried to take them off the screen they were all stuck to screen and when i finally got them off most of them brokeFor these, 1.5 - 2mm of bp meal + dex will work fine. Or, .5mm monocapa will also do it. When using monocapa can i use red iron oxide instead of black iron oxide ? Link to comment Share on other sites More sharing options...
Mia Posted August 18, 2015 Share Posted August 18, 2015 Try Ferro silicone works better. Link to comment Share on other sites More sharing options...

bpman Posted August 19, 2015 Share Posted August 19, 2015 Monocapa is intended to be used by itself. Link to comment Share on other sites More sharing options...
