Here are some methods for generating flame colours which give better results than the traditional nichrome wire.
- Using a spray bottle into a flame,
- Dissolving salts in methanol
- Absorbing them onto a sugar lump
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
