A history of glass
There has been evidence found by archaeologists of man-made glass, dating back to 4000 BC which were glazes used to coat stone beads. The first hollow glass container dates back to 1500 BC and the making of containers from glass blowing from the 1st century BC. At this time the glass was highly coloured because of impurities in the raw materials. By the 1st century AD colourless glass began to be produced and colouring materials added to make coloured glass.
The Romans brought their knowledge of glass making to Britain but kept their skills secret. This was until the fall of the Roman Empire when their knowledge and technical skills were then able to be learnt throughout Europe and the Middle East. There has been documentation of glass being made in the areas of Jarrow and Wearmouth around 68OAD and from the 13th century in The Weald, Surrey and Sussex.
A leading British glassmaker was George Ravenscroft (1632-1683) who is very well known for his work in developing clear lead crystal. This led to the production of optical lenses, microscopes and telescopes.
In 1851 The Crystal Palace was erected in Hyde Park, London for the Great Exhibition and was made of cast iron and plate glass. This was the beginning of using glass as a building material for public and domestic use.
Today the glass industry continues to thrive, as our use of glass features very strongly in our everyday lives, whether it is used for practical use or as a beautiful object to enjoy and admire.
Tools of the glass trade
The main tools used in the glass industry encompass a wide range of equipment and instruments that aid in the production, processing, and shaping of glass materials. Here are some key tools along with examples of their usage:
1. Glass Furnace:
The glass furnace is a crucial tool used to melt raw materials (such as sand, soda ash, and limestone) at high temperatures, creating molten glass. This liquid glass is then used to produce various glass products, such as bottles, windows, and containers.
2. Glass Blowing Pipe:
Glass blowers use a long, hollow tube called the glass blowing pipe to shape molten glass into various objects. By blowing air into the tube, they can expand the glass and form items like glassware, vases, and ornaments.
3. Glass Cutter:
The glass cutter is a handheld tool used to score or cut glass sheets accurately. It has a small, sharp wheel that creates a weak point in the glass, facilitating controlled breaking. Glaziers commonly use this tool to cut glass panes for windows and mirrors.
4. Glass Polishing Machine:
After cutting and shaping glass, a glass polishing machine is employed to smooth the edges and surfaces of glass pieces. It enhances their appearance and ensures safety, especially for glass tabletops and decorative items.
5. Glass Kiln:
The glass kiln is an essential tool for glass artists and craftsmen. It is used to anneal, or gradually cool, glass objects after shaping or blowing to relieve internal stresses. This process prevents the glass from shattering due to thermal shock and guarantees its durability.
6. Glazing Tools:
Glazing tools, such as putty knives and glazing points, are used to secure glass panes into frames, particularly in windows and doors. These tools help seal the glass within the frame, preventing air and water infiltration.
7. Glass Engraving Equipment:
Glass engraving equipment includes various tools like rotary drills, sandblasters, and engraving wheels. Artists use these tools to create intricate designs, patterns, or texts on the surface of glass items, such as glassware and decorative panels.
8. Glass Lamination Machine:
The glass lamination machine is used to sandwich layers of glass with a transparent interlayer, typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This process creates laminated safety glass used in windscreens and architectural applications.
9. Glass Testing Equipment:
Glass testing equipment is used to assess the quality and properties of glass, such as its strength, thermal resistance, and light transmission. These tests ensure compliance with safety standards in various applications, including construction and automotive industries.
10. Glass Recycling Machinery:
To promote sustainability, glass recycling machinery is employed to crush, clean, and separate glass waste into cullet, which can be melted down and reused in the production of new glass products.
These tools and equipment play a vital role in the glass industry, enabling the creation of a diverse range of glass products that are used in architecture, design, transportation, and everyday life across the UK.
Materials used in glass
Handmade glass is a craft that relies on various materials to create unique and exquisite pieces. Here are the main materials used in handmade glass, along with specific glass examples and their uses:
1. Silica Sand:
Silica sand is the primary ingredient in handmade glass, providing the basic structure and clarity. Glassblowers mix silica sand with other materials and heat it in a furnace to produce molten glass. This molten glass is then shaped into various objects, such as glass art sculptures and decorative glassware.
2. Soda Ash (Sodium Carbonate):
Soda ash is a fluxing agent used to lower the melting point of silica in the glassmaking process. It helps in creating a workable glass mixture. Handmade glass artists use soda ash in combination with silica sand and limestone to craft delicate glass vessels like bowls and vases.
3. Limestone:
Limestone is added to the glass mixture to stabilise the chemical composition and improve the durability of the final glass product. The combination of limestone, silica sand, and soda ash is used to create glass for architectural purposes, such as stained glass windows and glass panels.
4. Metal Oxides (Colorants):
Handmade glass can be infused with various metal oxides to achieve a range of vibrant colours. For example, cobalt oxide imparts a rich blue hue, while chromium oxide produces a green tint. These coloured glasses are commonly used in artistic glasswork, such as stained glass art and glass beads.
5. Borax (Boric Acid):
Borax is used as a fluxing agent in some glass formulations. It enhances the glasss resistance to thermal shock, making it suitable for applications like laboratory glassware, including test tubes and beakers.
6. Alumina (Aluminum Oxide):
Alumina is added to glass compositions to increase the glasss hardness and resistance to wear. Glass containing alumina is used in products like glass lenses for eyeglasses and optical equipment.
7. Lead Oxide (Lead Glass):
Adding lead oxide to the glass mixture results in lead glass, which has a higher refractive index and superior optical qualities. Lead glass is used in high-quality glassware, including crystal glassware and decorative glass figurines.
8. Barium Carbonate:
Barium carbonate is used as a substitute for lead oxide in some glass formulations. It imparts similar optical properties to lead glass and is used in the production of high-quality optical lenses and prisms.
9. Glass Frit:
Glass frit consists of finely crushed glass particles and is used in glass enamelling and glass casting. It can be applied to surfaces and then fused with heat to create intricate designs and patterns on glass objects like jewellery and art pieces.
10. Gold Leaf:
Gold leaf is used to add decorative accents to handmade glass items. It is applied to the surface of glass objects and fused in place during the glassblowing process, creating elegant gold patterns and motifs on high-end glassware and glass art.
These materials form the foundation of the art of handmade glass, allowing skilled craftsmen and artists in the UK to produce an array of exquisite glass creations that showcase both technical prowess and artistic expression.
Techniques of glass
By etching a plain piece of glass, you can create an interesting piece of art. Glass surface etchings are created by using abrasive, acidic or caustic materials after the glass has cooled.
Glass Surface Etchings
By etching a plain piece of glass, you can create an interesting piece of art. Glass surface etchings are created by using abrasive, acidic or caustic materials after the glass has cooled.
Acid Etching Glass
For safety reasons, you should wear protective gloves, long sleeves, goggles, and work in an area with good ventilation. Acid etching a piece of glass will give you a frosted glass look. You can write your door number on the glass above your front door, etch a mirror, etc. If you are etching door glass, it is a good idea to use 6mm laminated glass for security. You can practice using any glass object like an old jar or a drinking glass. Choose the piece of glass and the design that you want to etch into it.
Clean the Glass
Using glass cleaner and a soft cloth, free from lint, clean the surface to be etched. Place clear contact paper over the glass and remove any bubbles. Place the chosen design behind the glass and trace it onto the contact paper. If you are etching onto a mirror, trace the design onto the contact paper using carbon paper. Using an appropriate knife, cut away the contact paper from the areas to be etched.
Apply the Etching Cream
After ensuring all bubbles are removed, spread a layer of etching cream over the design using a paper towel. Wear rubber gloves to protect from the acidic etching cream. Leave the cream for about 10 minutes before running cool water over the design to remove the cream.
Finishing Off
Peel away the contact paper and run cool water over the finished etched glass.
Acid Formation
The formation of the acid used to etch the glass will produce different effects.
Alternative Techniques
Copper wheel engraving cuts the surface of the glass to create the pattern, then using progressively smoother wheels to polish the glass. In the late 19th century, craftsmen created a technique of sandblasting glass, which was cheaper than the more traditional acid method. Brilliant cut glass uses a large stone wheel to etch elaborate patterns into the glass.
