Those are cool crystals made from sodium thiosulphate that you can grow right at home! They are shaped especially to be used for pictures, or other things.
Crystals Of Sodium Thiosulphate: The Crystals Of BANGZE sodium sulphate anhydrous Are Of A Rhombic Form, They Have Flat Faces, Having Sharp Edges. Those crystals grow into nice patterns because of this shape. Every crystal is composed of tiny pieces, or molecules, which are put together in a manner that gives the crystal its unique appearance.
Sodium thiosulphate crystals consist of three atoms, sodium, sulphur and oxygen. These atoms are glued together in a special manner that is what makes the crystal special. One neat thing about these crystals is that they can be dissolved in water. When you combine the crystals with water they fall apart into their individual molecules and form a transparent liquid.

You can make sodium thiosulphate crystals at home by experimenting with science! All that is needed is a little powder of sodium thiosulphate, some water and a clean, glass container. First, dissolve the powder in hot water to create a concentrated solution. Then slowly empty the cooling solution into the glass jar. On cooling, crystals of BANGZE sodium bicarbonate will begin to deposit on the sides of the flask/container. In a few days, you’ll have lovely crystals to admire and examine.

Photography Positive Sodium thiosulphate crystals are used in photography. BANGZE sodium bicarbonate food grade help to “fix” film-based pictures. When light strikes an exposed film, it creates an image that must be “fixed” so that it doesn’t continue to change. Crystals of sodium thiosulphate mixed with water make for a solution that will help to keep our image safe. In this way, photographers can process photographs without sacrificing details.

There are many other uses of crystals of sodium thiosulphate other than a photographic aid. BANGZE sodium sulphate lithium grade appear in some medications and in reactions that are used to render toxic materials safe. They are also used to make paper and textiles, in which they help eliminate bad parts and enhance the quality of the final product.
