Muaj ob txoj hauv kev yooj yim. Ib qho siv tshuaj txhuam cawv, thiab lwm qhov nrog cov tshuaj potassium nitrate (muag ntawm cov chaw muag tshuaj thiab khw muag khoom raws li 'ntsev') Ob txoj hauv kev no muaj txiaj ntsig zoo.
Cov kauj ruam
Kauj Ruam 1. Rau cov cawv cawv, tsuas yog siv hlua khau, thiab tsau li 6 ntiv tes (15.2 cm) hauv cawv, li ob peb vib nas this, thiab tom qab ntawd siv sai dua tom qab, vim tias cawv yuav qhuav
Tsuas yog siv lub fuse thiab lub teeb. Qhov no yuav ua rau nplaim taws mus rau qhov tawg ntawm txoj hlua, tawm tsam mus rau qhov ua rau muaj txim, raws li qhov nruab nrab fuse.
Kauj Ruam 2. Rau cov poov tshuaj nitrate, sib tov cov poov tshuaj nrog piam thaj hauv lub ntim, ntawm qhov sib piv ntawm 1: 1
Kauj Ruam 3. Tom qab ntawd nqa daim hlua khau 6 ntiv tes (15.2 cm), thiab tsau nws hauv dej li ob peb feeb, thiab tom qab ntawd muab tso rau hauv lub thawv ntim cov poov tshuaj thiab piam thaj, yog li ntawd txoj hlua tau ua tiav
