The processing of glass into glass figures
What is glass actually made of and how is it processed into glass figures?
A question that is not just interesting for people who are interested in art.
Because the further processing of “handmade glass figurines” is definitely a special kind of
art and is fundamentally different from machine made glassware. While traditional craftsmanship requires a lot of tact and each artist lets their personal influence flow into their creations, glassware is mass-produced and done in piecework. Craftsmanship is a philosophy and gives every product a unique identity, let it be glass figurine, glass flowers, Christmas balls or candle light holders.
Let's start with the basics and definition of glass first.
Glass is an amorphous substance that is usually made by melting. When the solidification of melted glass happens, crystal germs form, which do not have enough time for the crystallization process.
Thus, the glass solidifies into one solid substance. However, if the glass is heated in the range of the glass transition temperature, it liquefies and can be further processed to glass figurines. The heat of the fire creates very different glass figures, which can be differentiated in size and type.
The glass from which glass figures are made is not just any type of glass, but a glass based on quartz sand and various plasticizers.
It is especially these plasticizers which ensure that the glass can be processed in the heat for a longer period of time without losing its shine, because that would happen with usual glass like glass bottles. In order to create glass figurines, a temperature of about 1000 ° C is required.
The further processing of glass into glass figures can look very different, for example the
creation of glass animals, glass flowers for decoration, Christmas balls or Christmas candle
light holders in different sizes. The glass is formed by turning it slightly in the fire.
It feels a little like honey on the spoon that one pans back and forth. The sparkling, watery beauty comes from the art of mouth blowing glass alone. Introduced in Rome for thousands of years ago, the practice of individual mouth blowing of glassware is a slow and beautiful process.
The colors and the delicate "wavy" texture of the hand-blown glass create lively, speckled
reflections that enliven the interior at any time of the day, any time of the year and at any
Glass blowing is an ancient craft in which molten glass become functional objects for design and architectural applications. It is a highly technical art form that requires special training and skills, as the magic of glass can only be created with talent and patience.
When You get into the mood for Christmas and the arranging of the Christmas balls on the
Christmas tree, have a closer look at the balls and You will see whether these are handmade or machine-made.
If You discover a little notch on the underside of the ball, You know it is handmade.
Because of the stake the glassblower can blow in the air and the ball is given its shape.
The stake is then slightly broken and cut off.
Mouth-blown Christmas balls and candle light holders are- just like glass flowers and
animals, heated in a gas flame and rotated.
At a temperature of approx. 1000 ° C, the ball is made of the viscous glass by blowing and
turning it freely into its shape.
They are then hand-painted and prepared for sale.
These Christmas decorations in the form of Christmas balls have been around since the
middle of the 19th century.
