They're glass
On copper
The glass is ground finer than sugar
And sifted onto a copper plate
Then it's placed in a small electric kiln
The drawings are made from copper wire
They sink into the first layer of glass
And get filled with a different color

That's the process simplified for your protection
I wear a mask when I sift the enamel on the copper
I use pliers, my fingers and anything in my sight to make the wires do what i want
I use tweezers to place the wires where I want them
I use dental tools to fill the drawings with the colored glass paste

I look like a mad scientist and spend a decent amount of time crawling on the floor
Looking for the piece of wire I always drop
But I'm enchanted by the end result
and I can't stop 
Because as much as I make the wires do what I want and place them where I want
They have a way of doing what they want and changing what I want

The glass does this too
I think I know what's going to come out of the kiln
And then I don't
The copper and glass get together and do something incredible
and I stand back and applaud
we've learned to work together, enamel and me.
