Creating Malachite egg
One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

Handmade crystal glass as a work of art
In order for the colored crystal to open in all its beauty and sparkle with every face natural light is required. Handmade crystal glass has specific tactile and aesthetic properties - it is pleasant to touch, it seems to radiate heat. To appreciate the quality and beauty of such things, of course, it is not enough to look at the picture.
Ostwald Process

Explosive limits
The range of concentrations over which a flammable vapour mixed with proper ratios of air will ignite or explode if a source of ignitions is provided.
Safranine
Also called "phenosafranine". A purplish-red, water-soluble dye, C18H14N4, used for textiles and as a stain in microscopy.
Zone Refining
A method of purifying a bar of metal by passing it through an induction heater, this causes impurties to move along a melted portion. This method applies the fact when a metal crystallizes on cooling, impurities are automatically expelled as they do not form part of the crystal.
