Product Information
Turn your scrap glass into frit with this heavy duty frit piston.

No need to waste those scrap off-cuts of glass lying around your studio. Turn them into frit to use in your glass projects with this easy to use gadget.

Place your glass into the frit piston, insert the upper plunger into the tube and plunge, it couldn't be simpler! You can create as much or as little as you want in any size ranging from powder to coarse. Why not crush up rods as well and create a custom blend?

Make sure the glass you use is compatible (e.g. don't mix float glass or bottle glass with Bullseye). All the glass we sell is inter-compatible (CoE90).

Always remember to wear safety goggles and a suitable mask!

Sift your frit into different grades using the Aanraku Frit Sifters, available separately.

I’ve only tried this once, with some clear offcuts, and have been unable to use the resulting fruit as it is contaminated with metal - I’ve tried removing this with the magnet, but it still looks really dirty. I am, sadly, very disappointed.

I'm finding this useful, in conjunction with the frit sieve. I create a disposable newspaper cowl, secured around the top of the piston with tape to stop powder being airborne.

I have found this very useful especially when I need frit of a particular size and colour and have run out. I use my mosaic cutters first so the bits of sheet glass are of a similar size. also I don't overload the piston with glass. I didn't find there was an excessive amount of powder produced. however I do find that it is quite loud. the magnet is very efficient at removing any metal filings.

You need the frit sifters to make the best use of this. I find it best to make a couple of passes with the pieces and not try and reduce everything in one go as that produces a lot of power. Instead after a short time I tip out the pieces and return the postage stamp sized pieces and repeat: fiddly but it has it's place for small volumes.

Found it really effective for smashing up the large pieces of cut offs that I have into smaller pieces, could do with some sort of cushioning around the handles. If you only have small pieces of offcuts to smash up, I would stick to a mortar and pestel. Brilliant for big pieces but takes a while once they get to a certain size. Also there is quite a bit of powder thrown up while in use, so needs to be used outside.

Disappointing. Not an efficient way of making frit. I pounded the glass for several periods of over a minute and still 50% of the glass was unusable as frit. I have had far more success with a simple stone mortar and pestle. It should also be used outside as it does throw up considerable quantities of glass powder into the air. The associated sifters on the other hand were very good. Very effective at grading the various sizes of the frit I did manage to create.
