humble potassium nitrate is hard to get in australia now. however, it is still easy and cheap to buy sparklers. so im gonna tell you how to concentrate the kno3 outta sparklers
materials:
1 kilo of sparklers (yea its a lot, but u need a lot)
mortar + pestle
2 buckets
sheet of thin linen
stove
first the annoying bit. Strip all the sparkler stuff off the wires, and collect it up.
then, get the powder, put it in the mortar, and crush it up untill it is ultra fine powder.
then fill one of the buckets with 4 litres of boiling water, and add the sparkler powder. stir and soak for about 5-10 min. loosely cover the other bucket in the thin linen (the linen acts as a filter) and pour the slurry on top.
give it 2 min to drain through, and squeeze out any excess water.
repeat 1 or 2 more times to get out the last of the kno3
evaporate the water at about 100 - 120 degrees c on the stove, u should see a load of crystals form. |
