Grinding glass rims

Featured Posts

I have several rather nice lead crystal glasses with minor chips in the rims, where I have either put them down carelessly after washing up or clunked them with the neck of the wine bottle. 

 

I'm reluctant to through them away as there were quite expensive (like a tenner each) so does anyone know a method of grinding the sharp bits down smooth, please? Photo to follow below.

 

I'm looking for details of what exactly tools/materials a glass specialist might use to remove a mm or so of glass please, rather than wild guesses and random suggestions from peeps who are trying to be helpful but are not familiar with working with glass. 

 

I appreciate the rim will be wonky afterwards but I'd rather that than the very sharp edges there now.

 

Many thanks for any advice.

I even have one of those!!! 

 

Thanks.

 

What sort of grinding bit? The  basic ones that come with the dremmel?

Me too.  Used a small conical grinding bit, probably carborundum like a sickle sharpening stone.

If you know anybody who makes jewellery and uses a Dremmel / jooltool (something with a Flexi-shaft preferably) as a polishing tool, then they should be able to take it to fine smooth finish for you. To the point where you will hardly know the chip was there. Know anyone who does Dichrioc Glass Fusing?

You can grind them flat across with water and fine grinding paste on a surface plate or a sheet of glass.

 

Getting a polish back on the edge is the tricky bit, toothpaste or jewellers'  works but slowly.

Fanx but I want to develop a technique for doing it myself as this is a an on-going problem. I want to keep the glasses in future instead of binning them!

There is  long term solution, can you guess what it is?

I would be very wary of starting with the Dremel technique if you are in any way clumsy [ the kind of person who tries to carry two expensive crystal glasses and a bottle of red wine in one hand]!

Fanx! 

 

I just gave a couple of glasses a go with the 10mm dia fine carborundum tip in the box of Dremmel bits. Worked fine for smoothing away the razor-sharp chip edges but draws attention to the fix now it is matt finish. Will get the polishy ones you linked!

You do realise that you may eventually end up with very short wine glasses, each with the capacity of a teaspoon dont you? ?

And he repairs chipped glass rims for a fiver each!

 

Once you add in your own travel time and cost, wouldn't it be cheaper just to buy new crystal glasses for a tenner each?

We have a large (1 litre) crystal glass decanter that had a BIG chip in the top. The local window glass shop was able to cut a slice off the top to remove the chipped bit, so we now have a serviceable 0.9 litre decanter, although it's a bit bottom-heavy!

Wear a mask if you’re grinding with a dremel, the glass dust is bad for your lungs. 

 

Thanks.

 

I was wearing my 'alien' mask, as usual. Would that do?

I've always used an oil stone

I've used a half-round (carbon steel) file to smooth out sharp edges.  No doubt there are better methods, but it has been sufficient to make the glasses safe to use
