Grinding Excess Glaze Drips

Recommended Posts

Hi guys! I was wondering what to do for grinding my own glaze drips off my pieces that are unwanted! Before I had my own studio, I was using a professional one of my friends that worked amazing but money wise I'm thinking of just getting a drill bit with a grinding stone on it! I have a feeling a grinding stone will take a lot longer than finding something electric, Any advice on which to get or what works for you please let me know :)

I use a dremel with grinding disks for small glaze drips; for larger drips, I use a bench grinder (usually for wood kiln fire wares). You don't need an expensive grinder.

 

The best/easiest glaze drips to grind are the ones that don't happen. Try to figure out how to reduce the glaze drips from happening by modifying your glaze or adding glaze drip lines to your wares to prevent running.

GOOD: chisel, silicon carbide rub brick, white stilt stone, etc.

BETTER: bench grinder, angle grinder, dremel, cutoff wheel, diamond blade, etc.

BEST: diamond bits -- look at what CI Products offers - they have fancy grinding discs for putting on bats for use on potters wheel, small bits for rotary tools, hand sanding/honing pads, diamond grinder accessories, etc.

Diamond Dremel bits do a wonderful job. The nickle-sized head with slightly round edges is the most useful shape. My father got several complete sets at a pawn shop for dirt cheap and gave me about 20 different shapes. A lucky score that I didn't even pay for!

 

I had use a 6" bench grinder with some of the guards removed before. This worked ok at removing the glass but the finish always showed the mistake poorly.

So if you like drippy glazes -- give yourself an accent line at the foot. Even a simple indentation acts like a hair on wet sheet of glass. The fluid will be pulled along the line before it drips down. A piece that has a foot like so:

will catch many of the drips before they reach the shelf.
