Pretty glazes, are they gas or electric fired?

I have a student that uses it with good results. I would contact the place you bought it.  It should come with a foil like tight seal over the top.  If the supplier doesn't help you, I would contact Spectrum.

In Topic: Is Low Fire Clay Easier To Hand Build With?

it's only a simple shallow tray form but has edges made from 3" wide strips of clay that are fastened to the side, then rolled out over the sidewall and back around to fasten again to the outside of the wall, leaving a hollow, round edging that looks like puffy fabric.

On my 2nd try, I rolled the initial slab much thinner, and worked wetter with better results.  I will try the lower grog clay tomorrow. perhaps 3rd time will work out the rest of the bugs.  Thanks for the clay advice.

You could stamp, bisque and fill the letters with a dark underglaze, wipe away any excess on the outer, unlettered surface with a claen, semi damp sponge, then , no wax, glaze the whole piece in a translucent glaze or clear celadon .  The letters will show through  fine.

OK, went to Highwater and Tucker clay info sites. 

I have some Tucker Mid Smooth Stone that says 'no grog or fireclay" but has 14.5% shrinkage.

Of the Highwater clays I have, Ellen Buff says "3% mullite,12% shrinkage ",  Brownstone has "3% fine grog" with 11% shrinkage and the Redstone I used lists " 6% kyanite with 10% shrinkage."  No info is given on grit size.  Is kyanite more /less an issue for me than mullite?

From this, I am assuming that as far as stoneware goes, the less grog, the more shrinkage.  So shrinkage will work against me after the piece is made, but less grog will help me get it put together. 

Is this right?

Does this info make the Tucker Mid Smooth Stone the best bet of the clays I have on hand?
