How to Make Glass

Glass plays many roles in the ever changing human civilization. But the process of making glass is actually the same like the process was in the early 19th century. Firstly, the ingredients of glass like sand, soda and limestone are put in a furnace. Then from now on the process, based on the shape of the glass, is divided into two types: plate glass and bottle glass. In the plate glass process, the ingredients from the furnace are moved by a conveyor belt through rollers which finally will shape those ingredients into plate glass. In the bottle glass process, after the furnace, the ingredients then put into a removable mould which let the air comes in, and then it will shape the glass like bottles we see on the shops. Finally those glass are ready to be sold. Those are the steps to make glass that we use in everyday life.

The first bridge, which is the biggest among the others and the best in its architecture, connects Batam Island and Rempang Island. Some people said that the first bridge is the miniature of San Francisco’s “Golden Gate” bridge due to its architecture.

Cinematography

The process of producing the illusion of a moving picture. Cinematography includes two phases: the taking of the picture with a camera and the showing of the picture with a projector. The camera captures the action by taking a series of still pictures at regular intervals; the projector flashes these pictures on a screen at the same frequency, thus producing an image on the screen that appears to move. This illusion is possible only because of the persistence of vision of the human eye. The still pictures appear on the screen many times a second, and although the screen is dark equally as long as it is lighted by the projected image, they do not seem to be a series of pictures but appear to the viewer to be one continuous picture.
