How To Achieve Cork-Like Appearance On Slabs

[mudwoman 1]

How do I get the appearance of cork on the surface of slabs? I've seen it done, tried a number of things, and nothing seems to work. Would appreciate any instructions, or links to articles, etc. (I've searched extensively for this, but just get information back on either pottery in Cork County, or using cork stoppers, etc.)

 

Thanks!

I don't know if this is what @mudwoman is looking for, but that is an intriguing tree-bark texture.  It is a little like Sodium Silicate crackle technique but seemingly more responsive to the brushed on thickness of the porcelain slip.  I'll have to add that to my wish list of things to try.

I like the texture too. But I don't think of cork looking at it.

closest thing i could think of,  they also darken the non white parts

mudwoman may be looking for something that is a result of tiny bits of clay being pressed together.  the spaces between look like the dark part of cork. with the correct color clay it is very close.

 

i tried to find the word "wodges" which one of our members mentioned recently but there was no result found.  if anyone knows where that is, the pot shown there does look like cork.  was it Min?  someone with a british influence?  babs?

That's a cool effect, Biglou13, but that's not what I'm looking for (although maybe I'd like to know more about that, as well). I can't find a picture of the cork effect in pottery, for the same reasons as I'm having trouble finding information - I just get results about using cork plugs in pottery, or cork items at Pottery Barn, or pottery from Cork in Ireland. I did have a couple of pieces with this effect at my Mom's house, but God only knows where they are now.

 

But the effect is like cork board. I've attached a picture of cork board, and the pottery surface I've seen is remarkably like it. I think sometimes an artist will sometimes add a wash that darkens the crevasses. I would contact the artists whose work I've seen, but one of them is long deceased, and the other I just saw somewhere long ago, and can't remember.

 

If anyone can recall who might have mentioned this previously, please let me know!

Min has a tutorial in her gallery where she gets a look that is similar to that, you could adapt and improve on it and I am sure get something close to that. Her's is a bit different, but I am sure it is in the direction you are looking for.

Is my pot similar to what you are looking for? If it is I would use clay that is a bit on the stiff side to keep more of the definition for the cork effect. Could easily make slabs instead of bowls, just press the clay pieces onto a bisque or plaster slab and work flat. Have to really smooth the back side of it or it will want to break apart at the joins when you bend a slab.

If you stuff the clay with loads of perlite, and then burn it out, you might get that "corky" look. Have a look at this work: http://antjhfoo.blogspot.dk/2010_02_01_archive.html

You can get such a texture on the surface of the slab by rolling fine sawdust from the wood shop, rice from the grocery store, or vermiculite/perlite from the garden center into the surface of the wet slab. The organic matter will burn out in the bisque firing, leaving tiny voids in the surface. Then finish it as desired (glaze, oxide wash, whatever). Try some samples first to see what you like.

THANK YOU JOSEPH!  yes, that is the one i meant.  it really has a cork look to it.   made with wodges.   that is why i could not find it when searching, it was in the gallery section.

[Joseph Fireborn 1,286]

No problem. I bookmark stuff like that, anything worthy of attempting later on in my career gets bookmarked!

Note: both Perlite and Vermiculite are not organic. Perlite is a form of obsidian formed by cooling volcanic glass. Vermiculite is expanded mica. Neither will burn out per se.

What would happen if you made a plaster mold of cork, then used the mold to press into the clay slab.  This would give you the texture.  You could underglaze or stain the recesses.
