You might think glass just rolls out of a machine, but that couldn’t be further from the truth. The majority of our collection is actually blown. A special craft, often handed down from father to son. It takes talent and years of experience for someone to blow big or complicated pieces.
To blow glass a molten glass blob is gathered from a crucible (also called “pot”) with a long, hollow iron blowpipe, at about 1,500 degrees Celsius. This process is also known as mold-blowing. By turning the pipe while blowing in it, the glass is centered on the pipe. By dipping this mass repeatedly in the liquid glass, more glass gets added on and the total mass can be enlarged. At this stage you can even add different colors of glass from different furnaces. You blow air into the pipe, which allows the object to expand. Most of the time, the object gets shaped in a mold. Molds are often made of wood (known as “klots”), but can also be metal. The wooden mold is cooled by water, but the extreme heat causes it to wear. This makes every blown glass object unique.
Subsequently, there are different ways to fabricate the edge of the object:
• With a fine burner: This produces a nice, smooth, lightly-thickened edge, which is very durable.
• Grinding: Heavy craftsmanship that creates a nice and taut result. Especially beautiful with a thicker glass-quality.
• Cutting: Also manual labor. The edge is cut with a special pair of scissors, and then heated again. This results in a robust, thick, organically formed edge that emphasizes the craftsmanship of this product.
• Folding: The edge gets folded manually in different ways. The result is beautiful and surprising, but because of the craftsmanship also in a different price range.
The finished product is led through another oven to cool down gradually. This process always causes small irregularities like little bubbles, and different colors and form,but this characterizes these very personal and hand crafted products.
Nowadays, part of our glass objects is partially or completely produced mechanically. By industrializing the process, we diminish the chances of bubbles and variations in form. Mostly these are the more sturdy products, which can show seams, depending on the mold and production process. This does increase the quality of the product and puts them in a different price-range. However, machines limit us in size and creativity.
Decorating: how do you color the glass?
As we described in the glass-blowing process, glass traditionally gets its color from using different glass-baths. Today there are more modern and safe spray paint techniques to dye the glass in every imaginable color. After dyeing the glass, it goes through a special oven in order to ensure perfect adhesion and water resistance.
How to clean glass
Glass is beautiful if it is clean and catches the sunlight, but if you use it, especially with flowers and plants, it gets dirty. We recommend washing all glass products in warm soapy water and rubbing it dry with a dishcloth. Be careful with dishwashers as the high temperatures can dissolve decorations. With creatively formed glass, you run the risk of breaking certain parts, as they all have their own particular temperature on which they expand.
