If you are familiar with glass blowing, you might not find much difference between glass blowing and lampworking. In the lampworking process, the workers use high-temperature torches to heat glass tubes and rods to such a point that the glass can be easily malleable.

Once the glass melts to that point, workers can give them any shape. They use the melted glass for making all kinds of objects that include beads, jewelry, marbles, drinking vessels, and decorative sculptures.

Different types of torches are available for lampworking. You can choose a gas torch, oxygen torch, minor torch, or hot head torch depending on your preference. Before trying this method, you will have to understand the basics. Once you feel confident, you can give it a try.

Microwave Kiln

If you like glass fusing and you cannot access a kiln, you can consider using a microwave kiln. You will not find a great difference between a microwave kiln and a kiln. The noticeable difference is the size. A microwave skin is small in size and will cost less as well. You can get one by spending only $50. A microwave kiln is made with ceramic fiber and looks like a small container

As the size is small to fit in your microwave, the project size will be limited. However, it can be perfect for small projects. You can use it to create small decorations and jewelry pendants.

Can I Melt Glass Without Any Fire or Flame?

Yes, you can melt glass without using a flame. Just think about what you will need to melt glass. It is not the fire but the temperature that melts the glass. If you do not want to use fire, you can use something that can give degrees C temperature. If this is possible, you can melt the glass in the absence of fire.

You will have to get something that can release lots of energy without causing ignitions.

Is there something that can help to get the desired temperature without fire? Yes, you can use an electric kiln. You can get the required temperature. It will help you to melt the glass and get the desired shape. It is easy to use as well. You can power on the kiln and get the required temperature. After this, you can level the glass in the kiln for about three hours. Also, electric kilns are more appreciated nowadays. They cause low SOx emissions, thermal NOx emission, and CO2 emission.  

In addition to this, you can use a solar furnace. You can use renewable energy to melt the glass. The concentrated solar heat can melt the glass like other above-mentioned options. The key is to know how to do it right. If you are inexperienced, you must do it under the supervision of experts.

When it comes to the temperature, the glass will need 1200 degrees C temperature to be melted. However, the wood will ignite at 700 degrees C temperature. It can ignite only at 500 degrees C temperature as well. Therefore, you should avoid this option.

Also, the molten glass can instantly ignite the wood. In addition to the temperature, the heat transfer can impact. If there is any way to prevent heat transfer, you can minimize the risk. However, it is suggested not to use wood to melt the glass.

What Makes a Kiln the Best Choice?

Most glass workers cannot work without a kiln. They do not consider other melting options since the kiln helps them with a better solution. In the current condition, kilns are more developed. They can be easily scheduled.

You can schedule them for a specific firing depending on your project requirements. They will heat the glass and maintain the programmed temperature. Also, they will use a specific cooling cycle to get correct annealing.

A kiln is the safest option to melt glass. However, you are going to spend more on a kiln. The benefit is that you will get a consistent result. Also, it will minimize the glass shattering and glass cracking to a great extent. All the credit goes to its annealing process. If you cannot afford a kiln, you can consider a microwave kiln. Even if it is small in size, it will offer the same benefits.
