A Three-Metal Mosaic

Posted by C Scheftic on 2012/02/23

Almost a year ago, I wrote a post describing and showing a pendant I think of as The Little (Oblong) Piece that Could (because, with each problem, I’d pick it up, dust it off, say a few words of encouragement, and keep it going to completion…).

On one side of that, trying to develop a collage (or mosaic) design, I was applying a series of pieces that went straight across the “base” piece. I’d moisten the base and the mosaic piece, press them together, and wait for that to dry. Then, I’d repeat the process with the next collage piece. But the backing piece, which would of course soften a bit as I applied each next piece, kept cracking along those long and straight borders, so I ended up adding a series of elements to the other side to reinforce it all. That was not a problem, of course, because I like making reversible pieces; I actually found it interesting to think about what I might add from both visual and structural considerations.

Still, there is another way to approach this issue right from the start: design the piece so that no border between the mosaic elements goes entirely across the piece! That is, use the collage pieces to provide the necessary structure right from the start. A very basic example of that is one of the Three-Metal Mosaic pieces I made earlier this winter.

The base of this piece (not shown) was made from Rose Bronze, as was the center rectangle (which is shown in the photo to the right here). Then, going clockwise and starting in the upper left corner, I added alternating “mosaic tiles” of copper and yellow bronze. Although there is some lining up of pairs, I was careful to have no “line” extend the whole way across the piece in any direction! This is the simplest way I know of to avoid the problem I kept having with The Little (Oblong) Piece that Could.

Once I had all these tiles fully assembled, I tidied up the edges as needed (with just a damp sponge; sanding only a tiny bit at the corners, to round them off slightly), and added the Rose Bronze bail. The colors you see are mostly just the differences between the three separate metals, enhanced a bit by some green kiln-produced coloring on both the yellow and rose bronze textured “tiles” in the mosaic (but not, curiously, on the smoothly-extruded bail).

Who knows why, but I don’t seem to have a photo of the other side. Still, trust me, this piece is another of my fully-reversible designs! The other side was made using a delicate texture of tiny flowers, and then embellished with “vines” and “coils” in the three different metals. Since it was while looking at some mosaics in one of the museums I visited last week when I began thinking that I didn’t remember writing a follow-up post to the one about The Little (Oblong) Piece that Could, however, at least I do have this shot of the side that matters for this comparison.
