Need To Make A Container That Looks Like A Loaf Of Bread For Donations

10 June 2014 - 11:59 AM

A church wants me to make a replacement for a ceramic donation box that broke. Once a month members are supposed to take food for the pantry, but people who forget are invited to drop a donation into a container on the table. The one they had (which I never saw) was made to look like a loaf of bread, with a slit in the top for donations and a hole in the bottom large enough for retrieving the money.

 

Any suggestions?  Could I use an unsliced loaf of actual bread as a form for hand building it?  Dry the bread out first?

 

Ideas?

How To Dry A Slab Built Dish Evenly

13 February 2014 - 05:06 PM

I'm having trouble with cracks forming at the edge of big (14 inches in diameter, that's big for me!) hand-built dishes while they are drying. Even thickness, about 1//4 to 1/3 inch, with an added foot ring slightly thicker.  Formed from a slab, with a pattern pressed in from a basketball net, draped over a bowl covered in T-shirt material or over a pillow made from a stretchy material with polystyrene beads inside. I gently ruffle the edges, i.e. 6 ups and 6 downs on the perimeter.  Clear?

 

I drape a lightweight cloth over it and then drape plastic over that and leave it for a couple of days.  Once it's dry enough to turn over, I do that, and continue to keep it all covered.  Still, the edges get completely dry while the center stays damp, and then a crack forms.  Of course!  In both cases, the crack came where the lines had been incised, so now I'm trying with no lines near the edge.  

 

If this one cracks, I'm in trouble!  I've promised it for a charity auction, to go with a smaller piece. made the same way, but deeper.  That one didn't crack!

 

I can't figure out how to get the center to dry more quickly, to keep up with the edges.  Should I use a heat gun on the foot ring and center?  Or should I spritz the edges frequently until the center catches up??

 

Ideas, potter friends & helpers? I'll try to post 2 photos. One of the last one with a clothes pin next to one of the cracks (not bisqued) and the other of the current one, made yesterday, draped over the pillow thing.

Why New Blisters On Re-Fired Glazed Pot?

29 October 2013 - 10:42 AM

I had a lovely bowl with one small glaze flaw/small blister crater inside. I dremeled it slightly and put a bit of clear glaze over the spot and re-fired it, again at cone 6.  Now it has blisters all over, inside and out! Ruined.  Why?

 

Laguna B-Mix cone 6 clay. Coyote's Ice Blue glaze.  One difference in the firing—fast speed the first time (although I forgot to take the prop out until late, so the lid was slightly open during the first 1700 degrees F)  and medium speed the second time.  Surely that couldn't have caused the new blisters, could it?

Underglaze On Lidded Pot Lids?

29 September 2013 - 02:33 PM

Will regular underglaze on leather hard clay applied to the rim of the pot and its lid cause them to stick together if fired together in bisque firing?

Fixing A Slightly Warped Wonderbat

03 September 2013 - 04:13 PM

I have used and loved my wonderbat with 6 square inserts for 3 or 4 years and stored it properly on its edge, but suddenly it won't seat completely level on the wheel head. There's a very slight wobble.  I cannot find a website for the manufacturer, Rocky Mountain Wood masters, but someone at Clay-Planet told me to wet it and weight it down on something level.  Before I try that, I'd like to know if any of you has experience with this product.   (I know that some have written in the past that this kind of bat isn't worth it, but I have found it delightful to use. I don't ever throw more than six items in one day, so I haven't had need for more inserts. I enjoy not having to remove a piece right away, and they save space on drying shelves. And I can easily remove the square from the round by sticking an old apple corer into the corner space. Works perfectly to lever it up!)

 

If I try this, how wet should I get the bat?

 

Love this community, by the way!
