Oil Paint on polymer clay?

I was wondering of just buying White Polymer Clay (Sculpey) and just mixing in the Oil Paint? Will that work if I just make it colored with the oil paint and then just bake it? Or will baking it change the color? I saw that I shouldn't use acrylic paint unless it's being painted after the baking.

    You DO NOT WANT TO BAKE OIL PAINT - the fumes are extremely toxic!!!!!

    Also, mixing in oil paint will change the consistency of polymer clay regardless of the brand. It will become unstable and unusable. Buy or mix the color that you want or plan to pain with acrylics / enamels after baking!

    It is definitely OKAY to use "oil paints" on top of baked polymer clay and also in small amounts mixed into the uncured clay to color it (or to color uncured liquid polymer clay).

    Artists oil paints (in tubes) are linseed oil based and work fine for polymer clay, though if used on top of the clay after baking they could take awhile to thoroughly dry (just like they would on any other surface).

    It's the "oil"-based substances which are *petroleum*-based though that are not good to use with cured polymer clay since polymer clay is the same type of substance and therefore can be dissolved by them (or at least made sticky over time).

    Those baddies would be paints (or clear finishes) that are "enamels" or say they *must* be thinned and cleaned up with paint thinner, etc--not cleaned up and thinned with water or linseed/vegetable oils.

    As mentioned, the paints and finishes that are usually used on top of hardened polymer clay are acrylics (but alcohol-based inks/etc can be used as well).

    Acrylics are are water-based so they aren't generally used inside the clay because the water in them will get trapped inside the oil-based clay and swell when heated, creating bubbles or plaques (areas of opacity)...if the clay is left out a while before baking and not much water-based colorant has been used, then that can sometimes work though.

    As for baking changing the color of polymer clays, that's true to some extent whether an extra colorant (or inclusion) has been added or not, but there are also ways to keeping that to a minimum.

    Unfortunately though, the bulk original plain "Sculpey" you mentioned is the worst for darkening of all the brands and lines of polymer clay, and will do it even at their recommended temps *even if you can manage to keep the temp reaching all parts of the clay* the temp you think it is--hard to do. Actually that particular line will turn purplish rather than turning browner/darker like all the others. (And also it's the worst for handling and for being weak in thin areas.)

    (Btw, SuperSculpey and Sculpey III are the next-worse for darkening, and Kato Polyclay is the best...the others are in-between and sometimes depends on the color or how much translucent may be in a particular color or color mix.)

    You can read all about the ways to avoid darkening as much as possible on this page at my polymer clay "encyclopedia" site:

    http://glassattic.com/polymer/baking.htm > Darkening, Scorching, Burning

    And the pages that cover using paints and inks, etc., as colorants inside the clay or on top of it are these:


    http://glassattic.com/polymer/letters_inks.htm > Alcohol Inks

    ...these pages are about mixing colors together to get thousands of new colors, and about using various colorants inside the clay to color it (like the paints/inks, but also including shavings from oil pastels, plus various kinds of more particulate "inclusions"):

    definite you may paint polymer clay. Acrylic paint works properly. Use a real coat appropriate for polymer clay. Why no longer in basic terms use distinctive colours so which you will no longer ought to paint. in basic terms use the properly suited coat to offer them a shine. Paint once you bake and it cools down thoroughly.
