Offhand glass blowing is one of two types of blowing glass, with lampworking being the other form. In this method, a bit of fused glass is accumulated at one end of a blowing iron or a blowpipe, which is a hollow steel tube. Through the use of special tools and molds, as well as blowing techniques, an artist transforms the glass into a new shape.

Lampworking is different from offhand glass blowing, because tubing and a glass rod are heated and softened with the lampworking method. Then, the softened glass is transformed into its final shape. Like the offhand method, lampworking also involves using special hand tools and blowing techniques in order to create the piece. Both practices are also concerned with gravity and the effects it has on the piece as it is being created.

When originally developed, lampworking used rods and tubes developed through offhand glass blowing. Today, special glass-drawing machines create the rods and tubes used by the lampworking glass artist. Therefore, the glass used by lampworking artists has previously been shaped. With offhand glass blowing, the glass used to create objects has never been made into a specific form. Rather, it is still a molten glob waiting to be shaped by the craftsperson.

Both types of glass blowing artists use similar tools. Nonetheless, some of the tools are different and frequently confused by the layman. For example, lampworking artists use a tool called a toche to help mix air and fuel in order to create a hotter flame for working with the glass. The toche is often also called a blowpipe, which is not the same as the blowpipe or blowing iron used by the offhand glass blowing artist to shape the glass by force of air.

Offhand glass blowing and lampworking each result in glass pieces with a distinctive look. Traditionally, lampworking was used to create test tubes and other items for use in a laboratory. The offhand method, on the other hand, was used mostly for artistic expression. Today, both forms are gaining in popularity for use in crafts and artistic creation, and they are among the fastest growing hobbies in the United States.

Frequently Asked Questions

What is offhand glass blowing?

Offhand glass blowing, also known as free-blowing, is a traditional technique where artisans shape molten glass into various forms without the use of molds. The glassblower uses tools like blowpipes, tongs, and shears, along with controlled breath and hand movements, to manipulate the glass. This method allows for a high degree of creativity and individual expression, making each piece unique. It's a skill that dates back to around the 1st century BC, according to the Corning Museum of Glass.

What are the basic steps involved in offhand glass blowing?

The process begins with gathering molten glass on the end of a blowpipe from a furnace. The glassblower then shapes the glass using tools and gravity, reheating it in a glory hole as needed to maintain workability. Air is blown into the pipe to create a bubble, which is further shaped into the desired form. Finally, the piece is cooled slowly in an annealing oven to prevent cracking, a crucial step in ensuring the durability of the glass.

How long does it take to learn offhand glass blowing?

Learning the basics of offhand glass blowing can take several weeks to months, but mastering the craft often requires years of practice. Aspiring glassblowers typically start with simple projects and gradually progress to more complex shapes and techniques. According to the Glass Art Society, many glass artists continue to refine their skills throughout their careers, as the possibilities for creativity and innovation in glass are virtually limitless.

What kind of objects can be made with offhand glass blowing?

Offhand glass blowing allows for the creation of a wide range of objects, from functional items like bowls, vases, and drinking glasses to intricate sculptures and decorative art pieces. The versatility of the technique means that glassblowers can produce both symmetrical and asymmetrical designs, incorporating colors, textures, and patterns as desired. The only limit is the artist's imagination and skill level.

Is offhand glass blowing an environmentally friendly practice?

Offhand glass blowing can be resource-intensive, as it requires high temperatures to melt and work the glass. However, many studios are adopting more sustainable practices, such as using recycled glass and investing in energy-efficient furnaces. Additionally, glass is a recyclable material, and the longevity of hand-blown glass items means they can be cherished for generations, reducing the need for disposable products. Artists and studios are increasingly mindful of their environmental impact, striving to balance their craft with ecological responsibility.

Sporkasia - You are not the only person who wants to learn to blow glass. I read somewhere that glass blowing is one of the fastest growing hobbies in the United States. I like watching someone else doing the craft, but blowing glass seems dangerous for the average person.


Drentel - I agree, glass blowing is great to watch and I think it would be even better if I could do it myself. Do you know there are glass blowing books? There are also videos that offer glass blowing instruction; and, even better, in some areas you can take classes from people who have mastered the art.

I first saw someone working with blown glass when I was in grade school. There was this guy who came to our school and entertained us during an assembly. It was amazing to watch. One moment there was nothing but a couple of tools, then in a short time, he had created some item, and it was fun to guess what the item was going to be as he produced it.
