How to make a polymer clay slip. Use this slip to smooth your creations, making them more realistic and finished. Its easy to do and takes only two ingredients--oil and leftover polymer clay!

I am using cooking oil (vegetable) but you can use your favorite polymer clay oils.

After you're finished carving your sculpture and you have removed all of the large faults, it is time for your polymer clay slip.

Take a small piece of polymer clay, the same color of your sculpture is a good idea, and place it on a hard surface.

Place a few drops of your choice of oil onto the clay. Use a blending tool, your fingers, or even a paintbrush to mix the clay with the oil. Make sure you get all of the oil and clay incorporated. You do not want even the smallest lump of clay left.

How much oil you use is up to you. I like both super thing and kind of thick slips. The project determines how much oil to mix in.

Very fine detailing requires a thinner slip and a very delicate/soft brush. You can use a drier brush to soak up too much slip, if you wish.

This slip can work as a glaze as well. It will add translucent color to your projects.

I allow my things to dry out a bit before baking the final project.

I had no idea.... this just solved an issue I've been having. Buying Sculpey glaze to finish off large works was getting too costly and nothing else seemed to be working. Going to try this with Sculpey Beige which is very similar to fimo. Wish me luck! (And thanks so much for the tip!)

Yeah polymer is awesome. I love working with it. My good friend Todd started buying polymer fairies online, which got me into making my own creations.

I'm a polymer clay newbie, so I think the idea of making a slip is a good idea! Other great uses for a slip would be a touch each of oil paint and liquid polymer clay (Translucent Liquid Sculpey, or TLS, being a good example of this) and a pea-sized amount of solid clay if you want something thicker. Am sharing it with people who enjoy this craft!
