[Underglaze Bleeding Wanted!]

I wonder if the apparent 'bleeding' is a technique used at the time the blue colorant was applied to the pieces - that was the way I achieved similar effect on canvas with water color and pastel crayons.  after lots of practice a "light" stroke with the "right" brush would produce the allusion of bleeding.

LT i was looking at the cups really closely and thinking what you are thinking because the bleeding is so uniform in the first set of cups. Almost like a perfect outline width of bleeding. When i had bleeding it was more like the white cups. Wonder if they didn’t like the bleeding and so applied gold on top.

[Underglaze Bleeding Wanted!]

i haven’t done this in a while but if i remember right the black mostly bled and i think a dark almost black blue bled.

does the clear move? i achieved the bleeding by applying the underglaze and immediately applying the clear glaze. lots of it - but not too much to cause the cloudiness.

thin lines have not bled that much. thicker lines with 3 or 4 coates of ug has bled. 

if i want the design to move i’ve applied glaze and then applied underglaze (though mostly cobalt) on top of the glaze. it does not bleed. it just shifts. 

also if i remember right, my walls bled, not the floors of the pots. 

good luck!!!

[How long is too long for Greenware]

Briana you are a newbie you said.  

I’d say forget about keeping.  Forget about firing.  Just keep throwing.  And trimming and then slicing in half to check for area of improvement. It’s been 2 1/2 years since I first touched the wheel.  I have kept none of the murder weapons from my first year.  I’ve always kept one piece from each semester to see how good I’ve gotten, but otherwise I’ve given away (mostly) sold (a few) almost all my pots.  I do bring them home to use to see what I like. So at the end of my semester I do a drastic cut of what I had at home from the previous semester.  

In the meantime try to find a studio or potter who will bisque for you.

As long as you keep good notes and know exactly what you knew when you trimmed the pot then time is no limit.  

However know that bone dried greenware is the most fragile state of clay to be moving around. Pack well but be prepared to lose some stuff. 

The other thing is sometimes you create cracks from too much handling that you might not see till after the glaze firing. So watch out for the ping after bisque. If you hear a thud or dull sound then either throw out or use it for glaze test.  

I have know people who have fired after 5 years.  But they hadn’t moved and they had notes.
