Frit Happens!

Frit Scrap   Glass fusers are fond of this little saying. But I am here to tell you that this is indeed not true! Turns out making frit is actually quite tedious.

Glass waste is always a byproduct of making any fused glass or stained glass piece. In an effort to recycle as much of this waste as I possibly can, I bought a frit maker.

The basic process of making frit involves putting scrap glass in a metal tube and then crushing it with another metal tube that has a blade like piece across the bottom. The slightly smaller crushing tube is placed inside the first and then you pound away. After pounding the frit is put into a set of nesting sifters that sort the frit by size. A strong magnet is placed in the glass and moved around to pick up any metal pieces that may have come off of the tube during the pounding.

Here is what I learned.

You can’t overfill the tube. This means it takes more time to make frit than you would think.

Crushing glass is a dusty process. A respirator and googles are a must. I placed a towel over the handle of the frit maker to keep the dust down.

It’s not fun… just sayin.

My conclusion is that I am not about to go making jars of frit from leftover glass. I have a variety of frit that I bought in jars. If I need a color that I don’t have and just need a small amount, I might do this. Maybe. Probably not. This could be something productive to do if there is an electrical outage.

I did get some good results on my clear scraps and was able to make a nice recycled glass bowl. Next time I think I will try putting the scrap in an old pillow case and just hit it with a hammer to see what results I get. I also remember seeing something online once about retrofitting an old garbage disposal to make frit. Maybe I need to look into that too!?

    I bought one, it was useless! I put scraps inside heavy duty, clear polythene and smash it with a ball hammer. You can see what you’re hitting because it’s transparent, and it keeps the dust down. I sieve it with 3 grades of bonsai sieves and store. Have a good batch of heavy duty poly bags though, they don’t last long!

    After I’ve washed my scraps I heat it up in my kiln to about 500 degrees celcius. And straight away I pour it intp very cold water. After that It’s easy to smash with a hammer between to sheets of thick paper.

    I smash mine with a hammer wrapped in the paper that my glass comes wrapped in or divided with. I make powder in a coffee grinder. That is easy but very dusty so have to wear a respirator. The blades are stainless steel so even though I go through it with a magnet I am not sure any metal fragments would be attracted. Haven’t had a metal inclusion issue yet though. I do this when I don’t have a color I need or run out, but it is kind of a pain. I can get exactly the sizes I want though. Good to do when I am lacking creativity or need to vent frustration.
