Glasswork by David Salganicoff
I had the opportunity of visiting The University of the Arts to take a glasswork class. This was an incredible experience and I learned a lot about the ins and outs of working with the material. We learned two different methods, cold and hot. You would expect being next to a 2500 degree furnace filled with 600 pounds of molten glass would be intimidating. You would be right at first, but as I worked, I became more comfortable in my surroundings and made a fairly cool piece with a blue and gold swirl that resembles a flame in the middle.
The way we worked with the hot glass was much different from anything I had done before. First we drew glass from a huge glass furnace with a metal rod. Then we heated it a bit more in another furnace to get a sturdier hold with the rod. Then we added color with a fine dust made of other pre colored crushed glass. Next, we used a wood block to form it into a ball. To remove it from the rod we scored it where the glass meets the rod till it was very thin, and we hit the rod with a solid object. The vibrations from the rod caused the object to break off. The objects needed to temper in a kiln for a week.
Cold glass works much like metals. You cut glass pieces by scoring lines and breaking along them. Then you sand the edges and arrange them onto a pattern. After you put every piece in place, it goes into a kiln to melt into a solid object.
