Feature Article - Casting MoldsThere are so many different types of casting molds, from the ones that you will with frit to the type that molten glass is poured into. The type of mold varies with the procedure.
Most individuals starting out in glass fusing generally try the frit casting method. Since this method only involves using a mold and filling it up with frit it can be easily accomplished inside the kiln. Usually it takes several firings to achieve a finished product since the frit slumps down into the mold during the heating process.
Most of us don’t have access or the opportunity to experience the hot casting method or sand casting. These processes require heating larger quantities of glass inside a furnace and more involved safety practices. Well, one of my friends, Michele has had the opportunity to take a glass casting class for four days. She claims it was hard work and she really got dirty, but she had tons of fun. She claims it was “Really exciting! No burns, but sure got dirty. Love playing with hot glass!” One of the pieces she did in this class actually was accepted in the University of Hawaii show! Way to go, Michele and what a fantastic experience!

Since Last E-ZineI have been having so much fun this month! I am only babysitting one day of the week now, so I am finally free to do other things. I feel like I have been given my wings again and I am able to fly….
If you have visited the home page recently, you will notice that I am adding videos to the site. I have been learning more about making and producing these videos. It is another educating experience. I want to do some videos to assist visitors in seeing and experiencing some of the processes, some movies to help individuals in finding the website, and some videos on some of the processes of glass fusing.
So far, I have done 3 or 4 movies to put on the website. If you are interested you can view the videos at:
Glassfus on Youtube.
I will be doing a “Fused Glass Class” video that will assist individuals new to glass fusing in learning the basics. I plan on making a visit to Arizona for that video, because I will be using my youngest daughter to star in the movie.
Reader QuestionRubie writes:
I have looked all over the Internet for how to make glass buttons and I finally found your site. You are the first person to mention using ceramic clay to make an impression that can be filled with glass frit. Are there any books that can teach me to do this? I want to copy some of the tiny, shank, old czeck glass buttons. Someone at a show suggested making a ceramic mold, filling it with frit, then laying a rod with kiln wash on it across the top, adding a little more frit, then firing it. I have a ceramic kiln, but I know nothing about glass and don't really know where to start. If you could give me some suggestions, I would be grateful.
Yes, your friend is correct in the way you could accomplish this...I don't however know of any books that could assist you with frit firing. Basically you need to know the fundamentals of glass fusing, and a mold that is deep enough for your particular design.
You would do just as your friend said...fill the mold with frit, place a kiln washed rod on top and adding more frit. You will find though that the frit will shrink and your rod probably won't even be covered at all in the initial firing...it would take a few firings to achieve what you are trying to accomplish...
Tips and TricksPurchase low-fire bisque ware to use for casting with frit or scrap glass. Make sure that it is constructed so that the glass will not get trapped.
