insutama Posted July 30, 2015 Share Posted July 30, 2015 Is it possible to make coloured stars without a chlorine doner such as parlon or pvc i have most the chemicals i need now except im still waiting for my parlon, red gum, and pvc to arrive so is there any star formula i can play around with that does not require these ?

PIL Posted July 30, 2015 Share Posted July 30, 2015 (edited) You can make red stars with strontium nitrate, potassium perchlorate, magnesium and dextrin. Yellow is quite easy, a potassium nitrate magnesium comp with sodium bicarbonate and dextrin will do the job. Green is quite challenging though. But you can still get an apple green color without organic chlorine donor.Barium nitrate 10Potassium perchlorate 4Magnesium 5Dextrin or other binder 2-3 Blue is impossible unless you have ammonium perchlorate Edited July 30, 2015 by PIL Link to comment Share on other sites More sharing options...
insutama Posted July 30, 2015 Author Share Posted July 30, 2015 awsome thanks and you say blue is impossible without a chlorine donor or just without AP in general ? Link to comment Share on other sites More sharing options...
insutama Posted July 30, 2015 Author Share Posted July 30, 2015 also i just have strontium carbonate at the moment my strontium nitrate is in the same package as the parlon lol would this work still for red ? Link to comment Share on other sites More sharing options...
PIL Posted July 30, 2015 Share Posted July 30, 2015 If you don't have an organic chlorine donor, the blue comp with AP produces best results. Blue needs a 'strong 'chlorine donor. Parlon and AP is, but potassium perchlorate isn't. And you can use strontium carbonate for red, but the red seems to be pale .You have to add much magnesium to release the strontium.

schroedinger Posted July 30, 2015 Share Posted July 30, 2015 For green you can also go with mg/bariusulfate 1:1. But how long can a parcel take? 1 week, just make up some streamers Link to comment Share on other sites More sharing options...

JOPETES Posted July 30, 2015 Share Posted July 30, 2015 for clear azure have to use copper oxychloride as it provides chlorine and is non-hygroscopic, the results are not bad. Link to comment Share on other sites More sharing options...
insutama Posted July 30, 2015 Author Share Posted July 30, 2015 when making the veline red star it says to use mgal 200 mesh im just wondering would spherical mgal work or does it have to be flake also would spherical aluminum work as well ?

PIL Posted July 30, 2015 Share Posted July 30, 2015 Spherical aluminum won't work. Both spherical MgAl and flake will work. Link to comment Share on other sites More sharing options...
ivars21 Posted July 30, 2015 Share Posted July 30, 2015 (edited) You can also go into advanced filter and exclude all stars that contains PVC, red gum or parlon: http://pyrodata.com/composition/filter-advanced?tid_2_op=or&advanced_filt[]=44&tid_op=or&tid_1_op=not&advanced_filft_large[]=265&advanced_filft_large[]=87&advanced_filft_large[]=65&tid_5_op=or&tid_4_op=or&tid_3_op=or&title_op=word&title=&description_2_op=%3D&description_2=&field_source_value_1_op=%3D&field_source_value_1=&field_video_video_url=All&field_table_check_value=All&description=All&description_1=All Edited July 30, 2015 by ivars21 Link to comment Share on other sites More sharing options...

Mumbles Posted July 31, 2015 Share Posted July 31, 2015 Spherical or flake MgAl don't exist. It's all granular. 1 Link to comment Share on other sites More sharing options...
insutama Posted July 31, 2015 Author Share Posted July 31, 2015 Oh really intresting if you ball milled mgal wouldn't it make it flake ? Link to comment Share on other sites More sharing options...
Mumbles Posted July 31, 2015 Share Posted July 31, 2015 Not the 50/50 alloy we use. It's quite brittle and would just fragment. I guess I shouldn't say that atomized Mg/Al doesn't exist, as it might. Everything I've ever used or seen has been granular though. Link to comment Share on other sites More sharing options...

Everything I've ever used or seen has been granular though.That's interesting, thank you.I have always considered my 150# MgAl as flakes, but I just took a closer look and compared it to some Al-flakes. I see the difference now Link to comment Share on other sites More sharing options...
