Scientific management and storage of glassware for daily use

Glassware for daily use belongs to consumable, its management and the daily management requirement of analytical instrument are basically same, namely the requirement is put in ark, classification is stored. Household glassware should be kept in different categories for easy access.

When glass was widely used, it was in the 18th century. This illustrates a point. Although glass was discovered and used long ago, ancient europeans were unable to produce it in large quantities and quickly because of the complexity of the manufacturing process. It was not until the 18th century that the manufacturing process was fully mastered and household glassware was widely used.

Before using purchased household glassware, including regular calibration of glassware, first, carefully inspect visually for signs of damage such as scratches, blurring, broken glass, scales or invisible scale marks. Damaged utensils should be discarded. For containers used in extreme conditions, such as those using corrosive substances or high temperatures, as well as containers and devices with mechanical vibrations, the frequency of visual inspection should be encrypted.

Glass products can also be subdivided into glass, plates, ornaments and other different types. In addition, not only colorless transparent glass products, there are ground glass, colored glass and so on. And transparency is different. In terms of materials, some household glassware has a smooth surface, some is carved and hollowed out, and some feels uneven.

Because everyday glassware can be easily hidden against a black background, the lines of the subject will become apparent and the shapes will be clearly delineated if white auxiliary lighting is used. In addition, in order to be able to take stereo images, the lamp needs to be placed in front. Next, we should be familiar with the use of fire board (this time use red fire board) to create halo effect. The transition of the halo from light to dark is a good explanation of the shape of the subject. Fire prevention board is used not only when photographing transparent object, the object that changes gradually when photographing color background can also be used reflect object and absorb object. As a result of the degree of fire prevention board bend is different, the effect is different also. This is something to look forward to.
