What is the difference between a glass rod and a glass tube?

In the glass processing industry, the raw materials include glass rods and glass tubes. So where are their differences mainly reflected:
1. Production process
 Glass rod: It is usually formed by dripping molten glass on a rotating rod, then stretching and cooling it, or by extrusion.
 Glass tube: The production process includes melting, molding, annealing and other steps. During the molding process, the glass liquid is blown into a tube, and then drawn or rotated.
2. Processing method
 Glass rod: Common processing methods include cutting, grinding and bending. Cutting uses a glass knife or a grinder, grinding uses a grindstone or sandpaper, and bending needs to be done after heating.
Glass tube: In addition to cutting, grinding and bending, special processing such as sealing and stretching can also be performed to meet different application requirements.
3. Application field
 Glass rod: It is widely used in the production of handicrafts and laboratory supplies, such as lampshades, lamp poles, syringes, etc.
Glass tube: used to make glass containers and crafts, such as teapots, water cups and wine bottles.
4.Product characteristics
Glass rod: has good thermal stability and chemical stability, as well as electrical insulation, and can resist the erosion of most chemicals.
Glass tube: has high transparency and good thermal stability, can withstand certain temperature changes, and observe the experimental process in real time.
In summary, there are obvious differences between glass rods and glass tubes in the production process, processing methods, application fields and product characteristics in the glass processing industry. These differences determine their specific applications and market demands in different fields.
