Fast burning star. Do not add binder, use acetone and bind with the Parlon. Addition of 5% binder cools the flame to Orange.
This is a VERY bright Yellow. Discovered by running out of CaCO3 and subbing BaCO3! My ooppps turned into “Thats cool!”. MgAl used is service grade, 200-325 from hobby chem. The use of straight 200 or 325 may get slightly different burn speeds without effecting the color.
