Introduction to pyrochemical demonstrations: Coloured smokes, coloured flames and sparklers
Introduction to pyrochemical demonstrations: Coloured smokes, coloured flames and sparklers is a complete document with compositions and the methods of preparation of Coloured smokes, flames and sparklers.
The most interesting demonstrations are those demonstrating the true magic of chemistry – that is, chemical reactions. Those who have a fume cupboard (hood) for demonstration purposes can broaden their spectrum of useful demonstrations by including the most beautiful effects known to mankind to their demonstration sets.
Many demonstration manuals include several reasonably safe “flash’n'boom” demonstrations. However, while these demonstrations are relatively easy to perform and do not require any special equipment, they still fail quite often and unexpectedly. This is often due to high sensitivity of the compositions, which prevents the demonstrators from making accurate preparations.
This document covers following topics:
* Introduction
* Preparation of dextrin
