Npaj pyrotechnic sib xyaw. Cov tswm ciab dawb ib txwm tuaj yeem tsim los ntawm 6 ntu los ntawm qhov hnyav ntawm cov poov tshuaj nitrate, 1 phaus. suav nrog cov leej faj, 1 wt. suav nrog stearin thiab 3 wt. suav nrog kev ua yeeb yaj kiab sulphurous. Txhawm rau kom tau txais hluav taws liab, koj yuav tsum sib tov 1 qhov hnyav. suav nrog magnesium lossis hmoov txhuas, 5, 5 wt. suav nrog cov chlorate potassium, 4, 5 wt. suav nrog ntub strontium nitrate thiab 3 wt. suav nrog hlau txuas. Koj tuaj yeem tau txais cov nplaim hluav taws daj los ntawm sib xyaw 1 qhov hnyav. suav nrog magnesium lossis aluminium hmoov, 5 wt. suav nrog ntub cov poov dej chlorate, 3 wt. suav nrog sodium oxalate thiab 3 wt. suav nrog hlau txuas. Qhov sib xyaw ntawm sawdust, hmoov thiab ntsev yuav tsum yog hauv av hauv mortar. Koj tuaj yeem yuav txhua yam uas koj xav tau los ua qhov sib xyaw ntawm txhua lub khw uas muag cov tshuaj lom neeg thiab cov cuab yeej kuaj sim.

Ncuav cov hmoov pyrotechnic sib tov rau qhov muab tshuaj txhuam thiab muab sib tov. Tom qab ntawd muab cov tshuaj tov rau hauv lub khob siab lossis lwm lub khob ntim. Tsau cov hlau ntawm cov hlau hauv qhov kev daws, qhuav thiab poob dua. Ua cov txheej txheem txuas ntxiv kom txog thaum cov tuab ntawm txheej daws ntawm cov hlau ncav cuag 5-6 hli. Qhuav cov khoom ib zaug dhau los thiab lub txim hluav taws xob tau npaj.
