Sprinkling Iron Filings On Wet Pots

Recommended Posts

Hi guys,

 

I am fairly new to ceramics and to this community. I wanted to ask if anyone had experiences/knowledge around sprinkling iron filings on pots with wet surfaces - right after glazing. Is it food safe? I know that there are glazes with high iron content but wanted to achieve a uneven effect with bigger speckles. This idea came about while watching and reading about a father and son potters from K. H. Wurtz. Here's a link of the video:

 

 

On their website under their bio they mention the use of iron filings sprinkled on pots too.

 

Any information about temperature, type of glazes, type of clay and their effects would be much appreciated.

 

Regards,

Jason

Wow! That was really beautiful. I like the gas powered heat gun - looks like more fun than electric. I think I will try the iron filings on a cone 9 piece or tile. There is another way to get that effect and its something I am working on with slip right now. I'll post pics when I succeed.

Yes, please share your experience. I am also curious as to how the temperature affects the iron filings.

When I used to salt glaze, I occasionally sprinkled iron spangles (fine iron filings - dust, really) into the flashing slips I used.

It worked extremely well, especially if you remembered to give the slip a good stir between applications - the iron spangles settled out from the rather thin slips quite quickly.

But the results were excellent; flashing with an extra dimension of speckled goodness, all under lovely saltiness.

Perhaps a variation on that idea would work for other ways of glazing - a thin (neutral) slip with iron spangles, applied at leather hard, bisqued, then glazed in the usual way.

 

Do you have any pictures of these?

I might have read this on CAD...I'm not sure.  You can take steel wool pads and bisque them to get lots of fine iron dust.  I put it on too thick and it was awful...no picture as the piece got pitched and I don't remember what glaze I used.  But, I gave some to a friend who lightly sprinkled it on wet white glaze and it turned out lovely.  I've been meaning to try again.
