homemade crucibles

[butcher]

What about buying a ready made dish and use the plastic sheet betweeen this dish and your fire clay, using the store bought dish for the mold, Your dish would be the next size up, but the same shape.

Darn as soon as the weather drys up I am going to have to start playing in the mud, you make it look fun. :lol:

nice that does give many clues to how your shaping and getting good looking crucibles.
I do not understand the use of the board with holes in it.

I make um.

If you can tell me the what for.

I'll send you one, 4 or 9 hole, your pick.

Everything in the kitchen is fair game. What I have using the ball is a deep dish.

Using kitchenware has caused me much grief with the woman of the house. She is unforgiving when it comes to her cooking equipment. I have learned, the hard way, to buy my own supplies or do without. Please keep us posted on your findings DONNZ.

Working on that next post. A bit long and may brake it down, two or three parts.
Have 17 pic's so far and captions. I have more but don't think it would be good to post so many at one time.
I would like to combine captions with pic's. It needs to be free. Photobucket?
I'm not up to date with all the tool available to me and how to use them.

And is there a ascending / descending option that I'm overlooking when I load my pic's.

Looking for clay: There's a possibility that something similar exist in your area.

I though she was going to cry when she found out someone out there wanted the clay. Students leave it on the shelf never to return. Two weeks later it goes to the dumpster.

I offered to buy it. She insisted that I take it. She couldn't tell me which was Low / High fire clay by looking at it. It looks like Longhorn White hand written on the bag.

Longhorn White - A smooth white talc bodied clay that fires from cone 06 to cone 1. Suitable for handbuilding and wheel throwing.

Never used, clean, and apparently unwanted.

I may have stumbled upon a better way of shaping. Rolling not good after closing the gap. Still working on pic's.

And on that wooded thing. I've made these for years and can remember only one person that knew what it was.

Egg shapped crucibles, wicked. :mrgreen:

A calcium lined crucible, a novel idea NoIdea.

To boil or not to boil, that is the question.

I will ponder.

Darn it was not a six-coffee-cup holder for the pickup truck; I like coffee going to work, Shucks if I would have guessed (egg holder), I would not be spilling my coffee on the floor-board going down the hill in the curves.

Eggs, I should have noticed the egg in one of your pictures, along with the other crucible molds, was wondering how well the egg would work to mold clay.

Nice work on the crucibles very impressive, thank you for sharing.

Thanks, butcher

Just a basic guide. Photo's got out of control. If I ever do something like that again I will do a story board in my TextEdit. Pic. number and caption as I go.
Couldn't function without it. Keep it in my Dock.
Don't know what they call that using Windows but I know they have one.

Looked that up, it's called TextPad in Windows.

I was thinking about using some of the finely crushed up (ball milled) ceramic from CPU's as part of the composition of the grog in a clay crucible, I was curious if anyone has tried this? I currently use ceramic CPU's as a heat shield, it seems to work extremely well. I am not sure what the ceramic composition of the tiles that cover the outside of the space shuttle are, but I got the idea of using it in the grog from that, and watching how the ceramic seems to be able to absorb, and deal with heat when you torch CPU's to knock caps off. I can hear it crack when I do so, and I am assuming that is whatever glass or other material separating from the ceramic when heated, but I thought that if it was mixed with crushed up fire brick and made up 40% of the material mixed with 60% of the refractory material, it might work very well.

Anyone have any advice, pointers, criticism or knowledge that might help?
