Is There Any Way To Give Stoneware White Clay The Look And Feel Of Terracotta?

Recommended Posts

Hi,

 

I throw with stoneware but would like to give the look and feel of terracotta to the clay. I use (Draycott stoneware). Do you know any recipe, maybe applying some slip or oxide colorant before throwing? Any recommendations? 

 

Thanks!

 

Andrea.

I do not use terracotta because I am high fire focused, but I like the color so I have experimented using some iron oxide to mimic that terra cotta look in standard cone 9-10 stoneware.

 

if you are making the clay try experimenting with some iron oxide in the clay body.   1% or 2% by weight should do it?  I have dirtied up some stoneware this way and it now looks (very?) similar to a local commercial red stoneware we have called RGH.

 

If you don't have control over the claybody agree that slip is the way to go.  Again 1% or 2% iron oxide added to 100% of your claybody should do the trick.

 

Let us know how you go.

Sorry to be so stingy on personal details. I guess it is a throwback to the days before social media when personal information was actually private rather than splashed around all over Internet (I am still appalled about what I can find out - and see - about myself or anyone else with a 30 second search)

I live in Perth Western Australia, an ancient land in geological terms (but isn't that true of pretty much everywhere?). It is a big place - imagine if the US had one state which started at Denver, stretched north and south from Canada to Mexico, and included everything west of there all the way to LA. Several Texases would fit inside it. Now imagine that the land area just described only contained about 2.5 million people , 80% of whom lived in LA and the rest scattered around everywhere else. Well that is pretty much Western Australia.

We have low hills here which back in the day were three times as high as the Rocky Mountains. They hold deposits of ALOT of stuff for anyone who is willing to go out and hunt for it (but again isn't that true of everywhere?). Iron ore is the headliner - most of the steel in the device you are touching now probably came from Western Australia (courtesy of the Chinese of course). There are also plenty of other minerals and many types and grades of clay deposits from very white creamy kaolin all the way to deep red ironstone. You could waste pretty much an entire potter's lifetime finding and testing different materials - something I am constantly in danger of out here on the far side of the planet.

Regarding "stuff", other than a range of ash glazes I am slowly working on (mostly eucalyptus ash), I am currently having fun using the many byproducts of my constant sample gathering to pollute my clay bodies and glazes. I sieve most things I pick up and use different "grades" of sieved-out material as additions to my plain old stoneware clay-bodies. This has provided some intriguing results, like the photos below.

oo la la is an understatement!  Lucky you!  Is the eucalyptus ash put into the glaze formula, or is it the result of the firing (with eucalyptus wood or leaves etc. ?).

The one I use the most in studio is an 5000 gram max electronic Ohaus that I bought on sale from Bailey but the one I use in the house which works just as well is the 8000 gram my weight  I got on amazon-there are many types but this one turns out is plenty accurate.You can get them for much less as well.For $34 its great for most applications.These new electronic scales hit me a few years back like a ton of bricks while reading about them here on this forum. I had been cave maning with my triple beam  for over 35 years and these scales have saved me so much time.  They also make a 7000 gram for less.

this one also look fine

the eucaplyptus ash comes from my fireplace and from the fireboxes on the wood kiln I help fire.   We don't really fire the wood kiln long enough to get substantial ash deposits on the pots.
