Glassblowing is the art of creating glass sculptures by manipulating molten glass in a very hot furnace. It is a fun way to express your creativity and try working with a new material. The most common and accessible type of glassblowing is called offhand, where you heat and shape the glass on the end of a hollow pipe. Blowing glass requires working closely with heat and glass, so make sure you take all the necessary precautions before you roll, blow, and shape the glass.
You could refer to following steps:
1. Gather the glass original material into a very hot(about 1090℃) furnace;
2. Put the pip into the furnace and gather the glass
3. Roll the glass on the marver to form a cylinder shape
4. Put the glass in the crucible, or glory hole, and turn it several times
5. Dip the glass into crushed colored glass to add color.
6. Roll it on the marver again. Try to get it to form the shape of a bullet. Keep the sides even and rounded so the glass is easier to blow.
1. Place the pipe on a stand. Use a steel stand that can hold the pipe securely. This will make blowing into the pipe easier.
2. Blow into the the pipe and roll it at the same time.
3. Return the glass back to the crucible to keep it hot.
4. Repeat the process until the glass is the size you want.
