[Clay Shrinkage]

Those shrinkage rates are more than close enough for what you're doing, and those numbers are way too precise. There will always be slight differences in shrinkage depending on the  accuracy of the firing, the thickness of the pieces, etc, so for them to give a number that precise is totally unnecessary. They basically have the same shrinkage rate.

Thank you so much!!! You made my day!!!

I hope it's okay to ask this question here.  I want to do a sculpture where I using a Cone 6 Terra red and White clay.  I need to connect the two but I can't find two that are exactly the same shrinkage with out the color changing on the Terra red.  Can you get away with the shrinkage off a little with out it cracking or breaking?  I was looking at two clays the Terra red is  at 11.48 % and the White at 11.37% shrinkage.  Would I be able to get away using them without be totally the same shrinkage rates? If so which one would I used to slip them together?

Thanks for your help!

[Slow Glaze Firing for Sculptural Work?]

I have a Skutt kiln with the newer electronic keyboard. I do have information from one skutts tech support on how to program your kiln to a  slow cool down.  I wanted to do this so I wouldn't get stress cracks in my sculptures. You can also verify that this will work for you have a Skutt kiln. I can post all the info if anyone is interested and the name and ext. of the Skutt tech I talked too.

[Wadding]

Hello,

Is it possible to use wadding on a bisque firing of cone 04 and then wadding on the glaze firing cone 5 or 6 on a hollow porcelain piece that has a small pour hole opening? Can you us wadding with porcelain?  Does the wadding just come off the piece?  Thank you!  I appreciate  all the help that any one can give me!!! Sandi

I have used busted up kiln elements on cone 5 bisque poured  slip porcelain with a low fire celadon glaze.  I put less glaze on the areas that sat on the elements.  I used a porcelain nichrome  support rod with center tower  for any pieces that stuck out away from the body.   The 12 pieces came out perfect but you need to test before you fire them.    Denice

The piece is slipped cast.  Can I ask where you got the porcelain Nichole support rods.  It is something I definitely want to look into and purchase.  Does the porcelain slip have a lot of memory like the clay?  Thank you for answering my post! Sandi

Does this piece have a flat bottom and glazed.  What temperature are you firing too?

It is going to be glazed. Firing at cone 5. It's a large egg. I trying putting the smaller ones on egg tilts but the area where the post showed up a couple hours later after the glaze firing.  I was going to put the larger one on a bed of nails stilt.  The piece was slipped casted.  Thank you for answering my post and trying to help me!

Hello,

Has anyone been successful at stilting entirely glazed pieces of non-functional like decorative pieces porcelain? If so could you explain in detail what you did.

Thank you,

[Stilts with Porcelain]

Thank you Bill. I would never have thought of that . I think I will try your suggestions. Sandi

[Stilts with Porcelain]

Thanks you for responding. The eggs are lay flat and the pour is on the bottom. That is what meant by horizontal.  Sorry sometimes I dont know the best wording to describe something. They will have raised englobes on them and glaze.  So I am worried that something will happen to the raised decoration if I don't elevate the through both the cone 04 and cone 5/6 firing.

Thank you,

Sandi

[Stilts with Porcelain]

Hello,

I am going to be casting some 2.5 inch horizontal porcelain eggs. This is the first time for to do these in porcelain. They are highly decorated.  I do not know if I want to only glaze parts or the whole egg. I was wondering since they highly decorated on bottom as well is it possible to use those egg stilts with the rod and insert them through the pour hole that is in the bottom or would they get dented. I would be using those rods in both the cone 04 firing and the cone 5/6 firing as well.  I use a bed of nails stilts for my larger eggs but the smaller eggs get a lot of stilts marks on them and even with grinding the stilts marks off the bottom surface looks awful.  Could you help me please! Thank you, Sandi

[Lusters]

Will  gold or copper luster leave  color residue on bisque  like gold or silver overglaze would, or would it burn off the bisque and leave the bisque color on changed like mother of pearl luster? The clay I am using is Amaco High Fire Buff #46  Thank you! Sandi
