Glassblowers use air to shape molten glass into a variety of products, from everyday items to artistic pieces. They may specialize in different mediums and use various techniques, including sandblasting and etching. Some work in small studios creating decorative items, while others manufacture scientific and industrial glass products. No formal education is required, but a background in art, metalwork, or industrial tool making is helpful.
Glassblowers create a wide range of glass products by forcing air into molten glass to form desired shapes. Some form everyday shapes such as bowls and cups, while others create more artistic forms such as ornaments and stained glass. Some professionals also work in the scientific field, manufacturing laboratory items such as test tubes and beakers. They can specialize in a variety of mediums or focus on one. Although a small number of people in this profession still blow glass by mouth, most use specialized equipment to manipulate the air.
Glassblowing, whether used to create artistic or practical items, requires excellent attention to detail and skills unique to the profession. Glass products are created by capturing drops of molten glass at the end of a tube and forcing air through the tube to expand the drop to the desired size. When the size is correct, the glassblower manipulates it manually or with machines to transform it into the chosen shape. After items dry, glassblowers typically inspect items to ensure they meet the quality level required by artists or clients.
Many in this profession work in small studios and produce decorative items such as stained glass, vases, lamp bases, decorative mirrors and ornaments. Some glassblowing artists only design and produce pieces for art shows and exhibitions. Glassblowers who manufacture glass tubes, pipes, test tubes, and other commercial, scientific, and industrial blown glass items often work in production and manufacturing environments. A significant number of glassblowers work exclusively in the field of glass repair, renovation and restoration.
In addition to blowing glass into various shapes using a blowing iron, glassblowers who fall under the artisan category typically apply other skills to their work. These techniques often include sandblasting the glass surface, etching patterns with acid, or etching decorative patterns around the perimeters of objects. Sometimes the pieces are adorned with colored or enameled glass that is welded into place.
Workers in the non-craft sector of this industry generally adhere to strict production guidelines set by medical, scientific, and industrial equipment professionals. These items typically include laboratory tools and apparatus, sample containers, and glass enclosures that require specific tempering. Glass tools and implements used for applications that resist metal surfaces are also commonly produced by commercial glassblowers.
No formal education is required for this job. A glassblower often has a background that includes instruction and education in art, metalwork, or industrial tool making. Some art institutes offer glassblowing classes, and some glassblowers offer private lessons for those who want to learn the art. Industrial glassblowers have traditionally received on-the-job training. Solid background in chemistry or physics is generally preferred for industrial positions.
