A little about glass
Since glass makes up the majority of the goods at us and is part of most people's everyday lives, it is time to introduce us to what glass really is. How much do you really know about glass?
The new year is hereby launched with a small introduction to the material, glass.
Glass consists of molten silica, quartz sand chalk and soda. This melts at 1400-1600 degrees. We have known of glass for over 3000 years, the earliest finds are from the Middle East, David's Collection has a great selection of early glass. However, our focus, in-store, is “recent times,” so we won't touch those early things.
Glass is a so-called amorphous (irregular) material. Its structure is not crystallized as ex iron. Glass can best be described as a solidified liquid material, so it is important to keep the glass moving during production until it has settled and can cool down. It has happened to many glass blowers that one thing has fallen on the floor as they have not kept the thing moving enough.
The unique property of glass is its ability to be shaped, penetrated by light as well as its ability to absorb metals and minerals in the melt, increasing the options for grindings or change in color.
You probably know the fine heavy crystal with its fine ring. These are added lead and manganese to give the glass sound and clean the glass of its natural gray tones, if too much manganese is added the glass becomes purple.
The green white wine glasses may contain chrom, iron or uranium oxides which are oxygen bonds. With gold one colors red, carbon gives brownish tones, sulfur gives amber and cobalt gives cobalt blue glass.
However, much depends on the cooling-off period and the speed, which in fact gives a myriad of color shades that especially collectors of hyacinth glass and children's glass know about - the colors are endless.
Ps. Nothing can leave the glass in use. Don't worry.
Hopefully, you have become a bit wiser about glass and will visit my shop.
