Hi, I am in charge of a 2nd grade public school project.  I had the children draw a picture of themselves on newsprint, then cut that out to use as a stencil.  We glazed coop bowls.  For the most part they turned out super cute.  The Public school kiln was dirty, and some dust got into some of the glaze work.  In one particular there was a big chunk.  When I removed the chunk there is no glaze left.  Is there any way to fix this?  The first attached picture is of the troubled bowl.  The second picture is of the divit.

 

Also, one of my test pieces cracked... any way to save this?  The 3rd picture is of the test bowl and the 4 picture is of the crack, showing that it does not go all the way through.  

 

 

Thank you in advance for your help.

The crack cannot be repaired. The dust either. But where the chuck came out, put a drop of glaze there and re-fire.

Great idea with the stencils!   Love it!   Bowls with cracks like that are usually in my cupboard until they go all the way.....

Thank you for your help.  Can you tell me about the re-firing, please?  Is it at the same original temp?  Should I scuff the area with a dremel first?

 

Again, thanks as this is for a 2nd grade class and I am winging it along with the general art teacher.  

 

I could not find out how to attach pictures to this post, so I added a few more to the original post.  

 

Thank you,

Francis

A few years ago, I did a project with a class of 6th graders at a private school.  We made bowls using slabs formed over plaster hump molds and decorated them with colored slips, followed by clear glaze.  One boy, who was attending the school on scholarship, said he was going to use his bowl every morning for breakfast because he had never had his own bowl before.  These types of projects can reach kids on so many levels.

I'd get rid of any roughness made by the chuck, and drop glaze into the mark and yes refire to original temp.

Brush the under sides of the kiln shelves with a stiff brush before using as its junk from them that has done this to your pots.

Nice bright bowls.

f these are tests, you could try sanding or grinding the dust if it's rough and painting a layer of glaze over the top. Then refire, but it's only a patch up but may make the bowl usable if it's a student's only bowl.

You should also vacuum out your kiln before using it again.  The bowls are cute.  The kids should be proud.
