[Challenge] 2023. April : Let's draw Glass

Glass is a very important object
in modern life.

It is also used as a tableware to
hold water or beverages, and
is also used as a window to block
the wind and show the scenery.

Various types of glass bottles
contain cosmetics and various
medicines, and in the dark of
the night, lights made of glass are

Glass is used in various places,
such as building a building made
entirely of glass, building a glass
greenhouse for growing crops, and
even lenses for everyday items
such as cameras and glasses.

technique of pouring molten glass
onto the end of a pipe and blowing
it through the mouth was used, and
cheap and efficient glassware
was made.

made, and our lives have changed
