In Topic: Underglazes Flaking Off

Yesterday, 01:20 PM

if you want to attempt it again with this piece, i'd try sanding down the area slightly with a dremel tool to remove the outer layer of clay that's causing the issue.  if that doesn't work, i'm out of ideas.

 

on a side note, fingernail polish looks pretty darn close to glaze when you need a touch up :)

to me, your example looks like a simple glaze holiday vs something like crawling from too thick application.  possible it was dust too.  also possible that it was a bubble coming through the glaze that didn't settle out, due to slight underfire or not long enough hold - but i'm less inclined to say it's this because the rest of the surface is even.

 

are the other failures identical to this?  same spot on all mugs?

no, the different slips should not bleed into one another unless you layer them when they are sloppy wet - and in that case it should be pretty obvious when you're witnessing the previous color bleeding into the 2nd bucket while you dip.  simply dip the object, let it dry to around leather-hard or slightly wetter (at least enough to lose its glossy sheen), then dip your next layer(s) and repeat.  one layer should net you a thickness roughly 1/16" thick is my guess (on a non-porous object), but truly depends on viscosity of the slip.  you can also do multiple layers of each color so they're thicker if you need it.

 

the main reasons why i suggested food coloring is because the stains or oxides are pricey, but also because it sounds like you're going to be wasting the materials by hosing them off...and then you have the environmental factor depending on where your materials end up once hosed off.  clay materials should be fine to wash off into environment, but once you start adding in metallic oxides in concentration we're talking about something different.

As we all know, ceramics is heavy already, and when you make it life size, you have more complications with transport and storage (unless you build in sections like we encourage many to do). Also many undergrads aren't art majors, many move housing yearly, don't have vehicles, or maybe don't have space in their shared living situation that can accommodate a 6ft 200lb sculpture. We do keep some work for our sculpture garden every year if it's presentable to the public, but for the most part is up to students what happens with their artwork. Of course we encourage everyone to hold on to their work as long as possible, so you at least give it time to sink in and really gather personal thought and feedback, or if you even just keep a small piece that represents what you wanted from your failed attempt.

When it comes time to dispose of it, we encourage it gets broken up so that you will not find your own work included or claimed in somebody else's work, or so that if/when you become successful as an artist, you had a choice regarding what past work exists (ex: in case someone dumpster dove your work 20yrs ago when you were an undergrad and it now has value). I'm sure many people here regret giving away old junky pottery that doesn't represent you very well, but that's what they and the people they show it off to know you by...

I know it's a shame to toss so much beautiful (hopefully it wasn't) artwork every year, but in reality you can always make more. It's similar to when I do throwing demos in HS classes and they gasp when I chop up a freshly thrown pot (that would have taken them all class period to make) just so I can show them a cross section of what/how I just did...because you can make more :) Usually when you do continue working, your work improves as you progress.

To a certain degree it is better to make unsuccessful art and be unhappy when you open up a kiln - this is because if you're truly interested in the material, then you will have more desire to improve and take steps to not repeat, hence you learn exponentially faster. When you open your kiln and everything is successful, you have a tendency to stop forward progression because you're already getting what you wanted.

In Topic: Looking For Ways To Color Slip

if you decide to use a mason stain, you should add around 10% to get the color intended.  add to a white slip base (in dry form) so you can weigh everything and duplicate the results in the future.
