Fused Glass Sinks
One of the hottest new trends is fused glass sinks. They are also called vessel sinks. These are most commonly used as a glass bathroom sink. There seems to be a high demand for these sinks combining the color and design offered by the use of glass. The most popular sinks are about 15-20 inches in diameter, and about 5-8 inches deep.
What are the different methods used to make these sinks? How durable are these vessels? How to make glass sink? There are a lot of questions about glass bathroom sinks. This page is created to help answer some of these questions.
There are three different methods used to make a glass bathroom sink. They are referred to as cold glass, warm glass and hot glass.
Cold glass is when the glass is worked on at room temperature. Examples of this type of work would be mosaic glass, stained glass, glass carving and glass etching.
Warm glass is when the glass has been heated in a kiln to temperatures to up to 1700 degrees Fahrenheit. Different kiln forming techniques are used to make these, such as fusing, slumping, etc. Pieces of glass can be combined and then fused to achieve a desired design. Once fused, the glass is slumped over a mold until it reaches the desired shape.
Hot glass is the process of blowing glass. The glass is gathered on a pipe and formed using a glory hole. Glass is layered onto the end of the rod and blown and formed into the sink shape. This method allows the individual to created different shapes and sizes.
These vessels must have a consistency in thickness and a flat bottom. A typical thickness ranges from ½ inch to ¾ inches. Once formed, these glass forms need to have a hole drilled in the bottom. The drilled hole usually has a beveled rim to allow the drain to rest level with the glass.
Of course we all know how fragile glass can be, so what care should be taken to insure that these vessels last? Since these pieces have been heated to a high temperature and then cooled, they are stronger. This process strengthens the glass making it 5-7 times stronger than normal unheated glass.
These sinks can withstand temperature variations of up to 70 degrees without cracking. Any abrupt temperature change can still result in thermal shock. Don’t pour water over 120 degrees into a glass sink. Don’t install a glass sink in an area where temperatures are not regulated. Wide temperature changes can also cause thermal shock and the vessel could crack.
These sinks are sturdy and can withstand an accidental dropping of small objects or bumping. Although larger heavy objects can shatter the glass sink.
Custom made fused glass sinks, are expensive to purchase. Making a fused glass sink will cut down the cost and allow you the creative pleasure of constructing them from scratch. The best part of making these vessels yourself is no one will ever have a sink exactly like yours.
