Joining PMC3 Pieces Dry to Dry


Here is how to join two flat surfaces in the construction process using PMC3.

Here are the two pieces I want to join. I am applying my maker’s mark, the small square, onto the back of a pendant.

I apply a generous drop of water onto one surface.

I set the other piece in place.

I make sure a nice layer of water touches every part where the two pieces make contact.

I rub the top piece back and forth on the bottom piece. I can feel as the sliding becomes progressively less easy, and am certaiin at that point to position my pieces well. Eventually, the top piece grabs and will not slide anymore.

What the rubbing does is create a thin layer of paste or slip between the two, as shown in the orange. This slip is very wet at first and acts like a lubricant. As it becomes thicker, it starts to set up like glue. 

I smooth the water around the joined pieces.

If I have way too much water I will wick some away or smooth it over the rest of the piece, as shown below.
I always leave a little water at the seam.

Just to be on the safe side, I let my piece sit at room temperture for a couple minutes before I accelerate the drying process.

The book Sculptural Metal Clay Jewelry by Kate McKinnon explains this process. The ring on its cover was joined by making the three different pieces, drying them, then joining them via this process. Scary, right?
