Attaching Dry Pieces To One Another

Recommended Posts

If you use Paperclay-Porcelain, what you want to do is ok. With just porcelain.... I don't know. I wouldn't try it with dry pieces. They can/will break.

Why not attach them in the just-before-leatherhard-stage? You don't have to wait until your piece is completely dry in the cast to take it out. You can take it out when it's still malleable.

And Judith is right: scoring, and maybe using the magical mix of water (or slip) and sodium silicate.

 

Fingers crossed for your project, startaro!

this is stuff ive been working on in other materials (resin, plaster, cement) and im trying to replicate these kinds of results with clay.

so even though each mold has a bunch of hands/fingers/toes i cant cast enough before the base shape (usually a hemisphere) dries... either that or i  cast a ton of little parts before i create the base shape, in which case most of the parts have dried by the time everything is ready to assemble.

 

any suggestions?

 

thanks!
