clay on baking spray ?

Recommended Posts

Hi,

Here it goes :

I sprayed baking spray on the desk - build a slab which I rolled in all directions, turning it upside down and vice versa.

There are, though,  several concavities on it , where the  slab is not  thick enough...

If I fill the places, where the slab is too thin, in the usual slab building technique, would it work? 

Or would it wreck havoc ?

Will the clay build up normally on the baking spray?   It is, well - oily ....

Or else...  how do I repair this unevenness ?

And what about the clay I have cut from the slab (with baking spray on both sides)? 

Could I reuse it just as if the baking spray wasn't there,  like normal clay ?  Or how do I bring it back to normal ?

 

Tell me where is fancy bred ?

If I fill the places, where the slab is too thin, in the usual slab building technique, would it work?    PROBABLY NOT

Or would it wreck havoc ?  I don't think "havoc" would be the word to use here..."messy" might be better

Will the clay build up normally on the baking spray?   It is, well - oily … Probably not...if it was just water, that would be OK

Or else...  how do I repair this unevenness ? Start with a new slab and use thickness rails to roll the clay out evenly

And what about the clay I have cut from the slab (with baking spray on both sides)? That clay should be usable unless you plan on joining pieces...that may be a problem

Could I reuse it just as if the baking spray wasn't there,  like normal clay ?  Or how do I bring it back to normal ? I don't know that there is a way to bring it back to "normal"... In the future you might try rolling the slab out on a piece of canvas or a piece of a sheet instead of a layer of oil...reserve the oily process for rolling out pizza dough...;)

No experience with baking spray (oil) on clay - but here are some thoughts:  

As for a patch - my guess is the oil will prevent the clay from melding together, rather than encouraging it as water does.  The patch may stick while it's moist - but will pop off as it dries or during the firing. 

Depending how much oil is on/in the clay, if you're only using it as a flat slab - to make tiles, for example - you might be OK thoroughly wedging then re-rolling.   The oil will burn out during bisque firing... whether the piece will hold together or not, you'll only know for certain once it dries and is fired. 

On the other hand, as Johnny said, if you need to attach other pieces to it, or are joining seams, it's probably not going to work. 

You might be able to get it back to normal (or close to it) by letting it dry, breaking into pieces, and slaking it down in a bucket of water...  (thought being the oil would float off as the clay dissolves.)  But unless it's a lot of clay and you're on an extremely tight budget, or you just want to find out if it works, it's probably best to toss it out and start fresh.

PS - if you decide to re-cycle, or continue through the firing, post back and let us know how it turns out.  You're probably not the only one that has (or will at some point) try using cooking spray on their slab table...  and your experience could be helpful to someone else.

Try slip and scoring it well and patching it with fresh clay, nothing to loose by trying. Lots of people use Pam or a similar veg spray on metal molds. If you do have to recycle the clay it will be fine.

read the contents on the spray can.   i know lots of people who use that stuff and do nothing special to the clay to reuse it.

 

what does your last sentence mean?

Thanks a lot !

I will make  an experiment and post it.  

The pieces I cut,  I will knead and make pieces for glaze trials.  I read everywhere about the use of cooking spray as mould release, and thought 

this problem  has  found  its solution a long time ago...

Have  a nice day !

That's from a poem, "Tell me where is fancy bred, in the heart or in the head", but  I can't remember the rest of it or who wrote it.   Obviously they were talking about making pottery....

Hi oldlady,

This is the beginnig of a song, written from Shakespeare.  

It ends with “ding, dong, bell, ding, dong, bell”

- the sound in my head at midnight, the platter had to be finished

and  I was writing here in the forums instead :)
