Stained Glass Kilns

 

Glass kilns are the equipment behind almost every glassware sold in the market today. Crystal vases, bowls, wine glasses and glass pendants are just some of these products. Kilns made glass a part of every person’s life. The principle behind the technology of kilning is actually no rocket science. A glass kiln can be likened to an oven. We use the oven to bake bread, while the kiln in the stained glass studieo on the other hand is used to bake ceramics, brick and glass. The kiln is also similar to a mold.

 

 

 

 

 

They say that glass is formed when lightning hits the sand. This makes us ponder how manufacturers are able to produce hundreds of items of glassware by relying on the power of lightning alone. It would be literally impossible. Glass kilns utilize the same principle that make lightning turn sand into glass. It uses heat.

 

Lampwork bead making can also take advantage of glass kilns.

 

The process of glass kiln-forming usually operates at 1100 and 1700 degrees Fahrenheit (600 to 925 Celcius). The ever increasing demand for glassware to be used in a variety of purposes brought the advent of creating glass kilns. Glassware comes in many different types and designs. Different types of glass kilns are used to produce different kinds of glassware.

 

In order to do that, glass kiln manufacturers produce different models. Though there are many different types of glass kilns, the one constant need among them in order to function properly is for the kiln operator to maintain control of the temperature. Gauging the temperature is used by pyrometers and pyrometric cones, which are calibrated specially for high heat. Intricate designs on glassware can be made because the glass kiln also functions as a mold.

 

The process of creating glassware through the use of a glass kiln can be summarized into five stages. The first is the heating stage where the temperature is the kiln is increased from room temperature to the temperature where fusing and slumping of glass take place. Next comes the soaking stage where the temperature in the kiln is maintained at a given point for a specific period of time.

 

The cooling stage and annealing stage come next respectively. Both stages are marked by a steady decrease in temperature. The annealing stage is significant because it is the critical point that relieves stress in the glass. Last is the cool-to-room temperature stage where the glass cools down to a point that is cool enough to be touched.

Glass kilns are not only available to large-scale manufacturers of glassware. There are actually smaller sizes available to those who will use to glass kiln for artwork or jewelry. When choosing the right kind of glass kiln to be purchased, the following should be considered. The dimensions of the largest piece you will want to fuse or slump and the number of items you want to fuse on multiple levels in one firing. Your power source should also be considered.

 

Glass kilns made glassware available to the rest of the world. Different types glass kilns made us enjoy and appreciate beautiful glass creations. Its creation opened new doors for artists to explore. More so, it made glass become an indispensable implement to everyone and a part of each person’s life.

 

Slumping Glass

 

If you wand to find out more about slumping you simply have to type this word in your favorite search engine. You will get plenty results and ways of using this method. You’re probably wondering what slumping is and how con be done?

 

This word is usually associated to heated glass that becomes soft and starts folding and hanging down. Usually this process is done in shapes. Being executed on top of objects this is called draping.

 

Glass becomes soft and starts curving at about 1200 f. This process can be achieved with just a piece of glass but it is usually achieved with several segments. First of all combine all the segments into a single one called full fuse before twisting into a shape. Since all the glass pieces fused into a single one, they’re shaped to fit the mass of the kiln pattern you’re going to use. After that, the processed piece is placed into the mold and inserted back into the heated kiln until it comes down as primed profile.

 

There many kind of molds that you can use for this procedure. There are molds of almost any shape and dimension that you can think of and for any occasion that you would like to observe. However before buying a mold make sure it is smaller than the size of your kiln’s inside.

 

First of all decide what you want to create. Than chose a mold and trim the glass to fit the form that you use. Be aware that the final result will very much look like the mass of glass placed in the mold.

 

Try to keep the glass size approximately equal to the size of the mold. If you make it bigger it will droop all over your mold and as a result the mold will be trapped inside the glass.

 

I stopped glass slumping a while ago. However I still love teaching others how to do it and I hope you’ll find these advices useful and you will become a glass slumping artist.
