Glazed 2-Part Forms

Just a recap of what worked and what didn't after the semester's last glaze firing.  Everything looks so different after it's been glazed.... I'm really thinking of just glazing all my pieces white.  They feel like strangers now!

These chalices were dipped in antique green on top and barium copper at the bottom.  I don't know why I haven't learned my lesson.... antique green should only be sprayed!  Good thing I gave lots of room for it to run into the barium copper.  That glaze tends to go pink when a little thick and heavily reduced.  Otherwise, nice variation from that glaze.  Only applied on the stem because it is not food safe.

A : sprayed Antique Green in a really light coat on outside.  Maybe too light?  Barium copper on inside.  Unfortunately there are several hairline fractures on this piece - very fragile, and it won't hold water.  It was among my favorite of this series... I will try again.

B : Antique Green on top, Barium copper on bottom.  Both glazes were sprayed... Really wanted more variation and contrast on this piece.  I guess I lost track of the number of times I sprayed the top - that Antique Green is too heavy again!

C : This entire piece is sprayed barium copper.  I really like the variation in this glaze, but there is too much pink for my taste - this piece was heavily reduced.  Chemistry is so funny and surprising...

These two were both surprises.  This is why you do a glaze test before committing.  I pulled this recipe out of a book, thinking it was the same that a classmate had used on one of her pieces.  Expecting an really neutral sage green with blush undertones I got this instead.  What a surprise!  Pentigill's Green.  Never again. 

These came out alright, though I was expecting more variation in them as well.  Turquoise Oribe.  My first real experiment with Oribes... 

And I can't forget to include the failures.  After I had such poor luck with the last series of mugs that I made for the Bardens (remember, the glaze ran and destroyed the bottom?) I tried to get another series thrown and glazed, trying to get them through the kilns before the semester was up.  To avoid the horrible pooling glaze, I brushed the glaze on the inside, then sprayed the outside with one coat of glaze and wiped down the bottom.  And as you can see, the antique green behaved well and they turned out quite nicely.  However, it was not protected from other work in the kiln.  One of my classmates glazed a piece of greenware and put it in a glaze firing kiln.  There was too much moisture in the piece and it exploded, leaving chunks of raw clay at the bottom of everyone else's work.  I think every piece in this kiln was ruined because of this oversight.  Very Frustrating!
