Clay Jar

This mosaic clay jar is a great way to use those left over polymer clay scraps. Never, ever throw those odd ball, mixed up, mashed up pieces away, again!

At times, I tend to be a bit of a hoarder with the clay, especially the nice colors. How silly is THAT!? I don't want to mess them all up and have leftovers, I don't know what to do with.

I got brave and used some of it for various projects and much to my dismay, then had quite a few left over pieces. This project was a good way to use those pieces up.

Mosaic Polymer Clay Jar Instructions

I'm sorry, I'm not able to be specific about how much I actually used. It was probably equivalent to about a 2 oz. package. It will depend on the size of jar you choose to use.

Condition the clay and roll through a clay machine, eventually getting down to the #4 setting.

Slice into one inch pieces. Cut angles so they aren't perfectly square and make various shapes.

Start from the bottom edge, putting the pieces on to the glass jar. Don't bother with the very underside of the jar. Leave about an 1/8th inch space between the pieces. Stagger the edges so none of the squares line up in a straight line.

Continue up the jar to just below the top edge (where the lid attaches). Don't do this part, for now. You need to leave this edge, so you have a place to hang on to, so you don't squish down the clay.

Roll the dark gray clay into very small, skinny snake shapes and start applying to the space in between the mosaic pattern. Smooth it down into this space, using your fingers and then a sculpting tool. This can be quite time consuming.

To save a lot of time, you could apply the squares over top of a sheet of the gray clay and then apply it to the glass. This would provide a different effect than what I was going for, though. I wanted it to look more like grout, between the shapes.

On the center of the clay jar, I made a dragonfly. The wings were made from slices of leftover millefiori cane. There is also a strip of flowers all the way around the jar, part way up.

Set the clay jar on your baking sheet now, so you won't have to touch it again, before it has been baked. Now finish off that very top edge that you haven't done yet. I finished off mine by applying a strip of dark gray clay and then adding slices of flower cane over that. If you don't have leftover flower millefiori cane, just add the same shapes that you have done on the rest of the jar, or even just a solid strip of clay around this top edge.

Bake in the oven according to the directions for the type of clay you have chosen. Be careful not to over bake. I used Sculpey III® and baked my project for about 15 minutes.

When cooled, apply two coats of sealer to your polymer clay jar.

I now have some place to put flowers when I can't locate an actual flower vase!
