BJV Posted September 18, 2012 Share Posted September 18, 2012 Hi All, I have a question. I have just rolled a few differentcolor star cores. Kyle Kepley's Emerald Green, Buell Redand Shimizu's B-70 Blue. Should I prime these cores with a hot prime beforeapplying Shimizu's changing relay? Below is the changing relay formula.Thanks,BJV Shimizu 's Changing Relay #1 Potassium perchlorate.............................35Potassium nitrate.................................35Hemp coal (or Paulownia coal).....................24Soluble glutinous rice starch.....................6 Link to comment Share on other sites More sharing options...
ExplosiveCoek Posted September 18, 2012 Share Posted September 18, 2012 (edited) Changing relay will light color stars reliably . So no hotprime is required. Edited September 18, 2012 by ExplosiveCoek Link to comment Share on other sites More sharing options...
