kitchen and chemistry

Hello world , i have contract the flu , but this can't stop me , even better I am seclusive at home so I have much time to spend writing here .Today is thursday , this is the day of the chemical reaction .I have choose this picture on the left for a reason : working with chemicals can always be dangerous , so you can perform the experiment I'll suggest you week after week only if you are an expert chemist and wearing all the protective stuff necessary .After this suitable handful of advice , we can start with the chemistry .
Some history before : in the ancient India , priest pressed in pyramidal or spherical shape stronzium salts with carbon , potassium chlorate , sulphur and burnt them in the semi-darkness of the temple : them were the 'bengala'.
Attention! The reaction raise a big amount of fume .Potassium chlorate and sugar must never be mixed up in a mortar , they can give an explosive reaction .
Tools : paper sheets , fireproof plate , pipettes , gloves and glasses
Reagents: Potassium chlorate , sugar powder , barium nitrate , stronzium nitrate , sodium nitrate
Red fire : 10 g KClO3 , 10 g sugar , 20 g Sr(NO3)2
Green fire : 10 g KClO3 , 10 g sugar , 20 g Ba(NO3)2
Yellow fire : 10g KClO3 , 10 g sugar , 20 g NaNO3
Execution : the substances are put on a big paper sheet , blended swinging carefully the paper and pored on the fireproof plate in a sausage shape .The blend can be burnt pipetting 1-2 drops of concentrated sulfuric acid on one extremity of the mix
Final treatment : the ashes are mixed with a NaOH (aq) solution , the filtered can be poured through the sink , the deposit stored in the heavy metal waste .
