Explanation of microcrystal pictures

Pictures of commercial textile auxiliaries and their raw materials were taken. Textile auxiliaries are chemical substances that are used for manufacturing (eg spinning, weaving) or finishing (eg bleaching, dyeing, improving performance properties) textile materials.

The reason for shapes and colours in the micropreparation is the crystalline structure of the substances examined.

In general, a crystal is a body that is limited by flat surfaces, straight edges and angles. In the physical sense, crystalline matter consists of uniform structures (atoms, ions, molecules) in the form of uniform space lattices. Crystals expose different characteristics in different directions (optical refraction, diversification). What is characteristic of crystals is homogeneity and anisotropy (different behaviour in different directions).

Depending on the transmission direction, light rays in crystals are refracted and diverted (double refraction) at a different strength. If polarised light (oscillating in one direction only) is used, interferences (of light waves) arise, which result in splendid colour effects. Similar effects can be observed in coloured soap bubbles or oil films shimmering in many colours.

Crystals form from molten mass, from solutions or gas phases. The conditions during crystallisation (eg temperature, speed, number of crystal nuclei) strongly influence the colour and shape of crystals. The scientific benefit of this procedure is only limited.

The preparations (thin substance layers between object holder and cover glass) have been examined in transmitted light in a polarising microscope. The scale of the photos is between 200:1 and 800:1.
