#52794 Act Of Vandalism . . . Or Is Turnabout Fair Play?

Posted by BeckyH on 18 February 2014 - 08:21 AM

At least a piece by Ai Wei Wei is replaceable, somewhat. Unlike the piece Ai dropped as a statement. Destroying the irreplaceable for political commentary is no more commendable than destroying current work is.

#42232 3D Printing Clay

Posted by BeckyH on 08 September 2013 - 04:37 AM

There are places that 3D print ceramics. Shapeways is one company that will do so. I'm not sure if ceramic printers are available for home use yet, but it won't be long.

#41078 Cracking In Mold

Posted by BeckyH on 19 August 2013 - 10:47 PM

When does it crack? What shape is the object you are casting? Long, narrow stems will crack where they attach to the bowl of a goblet. Plates and bowls tend to crack across the bottom.
A few possible reasons:
The differences in thickness of different parts of the object are great enough that they dry at very different rates.
You are dumping the extra slip before the casting is thick enough.
You are letting your casting get too dry in the mold. You should pull it out when it is leather hard.
Do you use a defloculant? If your slip is sludgy instead of smooth and creamy the differences in viscosity can cause problems.

To make different size tiles, just cut the grid to the size you want. You can use an exatco knife, or scissors if the grid is thin enough.

Did you see the recently posted video about this very topic? Damp newsprint is the way to go! Cheap, sticks well, peels off cleanly.
