This describes a method of carrying out flame tests by spraying a solution from an atomiser into a flame – this gives a better colour than the traditional platinum wire method.
Some versions use solutions in ethanol but this will give a coloured flame anyway. We prefer to use aqueous solutions.
Small spray bottles can, we are informed by Dr Bunhead, be made from Fruit Shoots.
For generating a longer-lasting flame colour, various methods are described in an article in SSERC Bulletin 178 – Here
