How to make purple glass

Glassblowing is a centuries-old craft that has been used to create beautiful and unique glass objects. Making purple glass is a popular technique that involves combining different colored glass to create a unique hue. This guide will walk you through the steps of how to make purple glass via glassblowing.


– Clear glass
– Cobalt glass
– Propane-oxygen torch
– Graphite marver
– Safety glasses
– Apron

Step One: Preparing the Glass

Begin by gathering the necessary materials including clear glass, cobalt glass, and a propane-oxygen torch. Then, make sure to put on the safety glasses and apron for protection.

Step Two: Blowing the Glass

Now, it’s time to begin the glassblowing process. Start by heating the clear glass in the propane-oxygen torch and then use a graphite marver to shape the glass.

Step Three: Adding the Cobalt Glass

Once the clear glass has been heated and shaped, it’s time to add the cobalt glass. This can be done by heating the cobalt glass in the propane-oxygen torch and then adding it to the clear glass.

Step Four: Blowing the Glass Again

Once the cobalt glass has been added, use the propane-oxygen torch and graphite marver to shape the glass again. This will help to create a uniform purple hue.

Step Five: Cooling the Glass

Finally, it’s time to cool the glass. This can be done by placing the glass in a kiln to cool slowly. This will help to ensure the purple hue is even and consistent.


Making purple glass via glassblowing is a unique and fun craft that can produce beautiful and unique pieces. This guide has walked you through the steps of how to make purple glass and with a bit of practice, anyone can become a master glassblower!

1. Gather the necessary supplies including a propane or natural gas torch, a glass blowing pipe, a marver, a glass punty, and the raw materials needed to make the glass (silica sand, soda ash, limestone, and a small amount of cobalt oxide).

2. Heat the glass blowing pipe to a uniform temperature in the flame of the torch.

3. Place the raw materials into the glass blowing pipe and roll the materials on the marver to form a ball of glass.

4. Heat the glass ball in the flame of the torch until it becomes molten.

5. Add cobalt oxide to the molten glass and stir it in with the glass blowing pipe. The amount of cobalt oxide added will determine the shade of purple glass created.

6. Use the glass punty to pick up the glass ball from the glass blowing pipe.

7. Shape the glass ball on the marver to form the desired shape.

8. Place the glass back in the flame of the torch and heat until it is malleable.

9. Use the glass blowing pipe to shape the glass into the desired shape.

10. Place the finished glass piece in the annealer to cool slowly.

How Purple Glass is Manufactured: A Guide to the Process

Purple glass is made through the same process as other types of glass. The process involves mixing sand, soda ash, and limestone together to create a liquid called glass batch. This batch is heated to a high temperature, usually around 2,500 degrees Fahrenheit, in a furnace with a variety of fuels.

Once the glass is melted, various additives are added to achieve the desired color. For purple glass, a combination of manganese and cobalt is usually used. The glass is continuously stirred to ensure that it is evenly mixed and that the color is consistent throughout.

The glass is then shaped into the desired form. For purple glass, this is usually done by blowing or pressing it into a mold. The glass is then cooled slowly, to prevent cracking or breakage.

Once cooled, the glass goes through a polishing process to give it a smooth, glossy finish. It is then ready for use.

What Mineral Makes Glass Purple? – Exploring the Color Purple in Glass Production

The color purple in glass production is created by adding manganese dioxide to the glass mixture. Manganese dioxide is a mineral, usually found in the form of pyrolusite, that helps to absorb ultraviolet light. This absorption of ultraviolet light gives the glass a purple hue. Manganese dioxide has been used in glass production since ancient times, and was used to make stained glass windows in churches, cathedrals, and other places of worship. The use of manganese dioxide in glass production has also been used to create a wide range of shades of purple, from a very pale hue to a deep, dark amethyst.

What Type of Glass Transforms Into a Vibrant Shade of Purple?

The type of glass that transforms into a vibrant shade of purple is called dichroic glass. This type of glass is made by adding certain metals to the surface of the glass, which results in a glass that reflects and transmits light in different directions and changes color depending on the angle of the light. Dichroic glass can be used for a variety of purposes, including jewelry, decorative pieces, and even art installations.

How Is Purple Stained Glass Made? – A Guide to Crafting Stained Glass Art

Purple stained glass is a type of art glass that is made by combining a pigment with a glass powder, which is then fired in a kiln. The result is a beautiful piece of art that can be used to create stunning windows, lamps, or decorations.

The process of making stained glass involves several steps. First, the glass powder is mixed with a pigment such as cobalt, titanium dioxide, or chrome. This mixture is then heated in a kiln until the desired color is achieved. The glass is then cut, shaped, and polished to create the desired shape.

Once the stained glass is finished, it is then coated with a protective layer of lacquer or varnish. This layer helps protect the glass from scratches and other environmental damage.

The final step in the stained glass making process is the installation of the glass. Depending on the project, the stained glass can be set in a frame or set directly into a wall.

Making stained glass is a complex and time-consuming process, but it can be a rewarding and beautiful hobby. With a bit of practice, anyone can learn to make beautiful stained glass art.

Overall, this guide provides an informative and comprehensive explanation on how to make purple glass. The step-by-step instructions and images make it easy to follow, and the tips on using the right materials and techniques are extremely helpful. It is important to remember that the quality of the glass depends on the quality of the ingredients and the skills of the glassmaker. Therefore, it is recommended to practice and perfect the technique before attempting to make larger and more intricate pieces.

1. Start by gathering a supply of clear glass and a small amount of cobalt oxide.

2. Heat the glass to around 1600°F (870°C) in a furnace or torch.

3. Once the glass has reached the desired temperature, add a tiny amount of cobalt oxide to the molten glass.

4. Gently stir the cobalt oxide into the glass until the desired color is achieved.

5. Use a blowpipe to shape the glass into the desired form.

6. Cool the glass in an annealing oven to help prevent it from cracking.

7. Once the glass has cooled, it is ready for use.
