Been experimenting with coloured liguid fimo, I thought food colouring would work so that the colour is smooth and slightly see through, it has when I have used it before in thinner areas. But I am pouring the liquid stuff into a mould now, which is about a cm deep, and the items came out opaquey and blotchy. What can I use that won't do this? Will using a tiny bit of coloured clay work, and still keep the translucency? Oils paints? I dunno, please help!:)

You shouldn't use anything water-based inside solid or liquid polymer clay because the water will just get trapped inside the oil-based clay and turn to steam when baked.  Those areas of moisture cause little bubbles or areas of opacity in otherwise translucent clays or liquid clay --which will also happen more in thicker areas because there's more moisture, and also because it hasn't had as good a chance to evaporate out of the clay before heating.  (You might be able to use food coloring if you let it dry out first, then mix the flakes into the clay if you can.)

There are many other colorants that can be used in solid and liquid polymer clays, but the two most common are probably artists' oil paints (can be purchased in little kits of colors, if you want) and alcohol-based inks (Pinata and Adirondack, e.g.).  Both are fairly transparent but the alcohol inks will be the most transparent possible.  Various pure pigments can be used too, but usually aren't.

You can use solid clay as a colorant too.  If you don't use too much of it, the new mix will stay fairly translucent.  But if you want the most transparency from solid clays you'll want to use solid clays that already have the most translucency from the factory.  To find out which those are, press a small blob of each color-brand flat on a sheet of plastic or glass, then shine a flashlight up through them in a dark place (closet, etc.)... you'll easily see which are most translucent.

You can mix all kinds of colors btw by mixing the colored (solid or liquid) clays you've already made, or you can mix the inks or paints themselves to create a new color before tinting the clay with them.


You can read about the various colorants that can be used in solid or liquid polymer clays on these pages of my site if you want lots more detail:

and for more on each:

(...click on Alcohol Inks, under Inks)
http://www.glassattic.com/polymer/paints.htm
(...click on Oils... or also on Oil Pastels, Fabric Dyes, etc.)

And for lots of info on coloring clay in general, plus color recipes, etc., see:

(...click on Basic Info... then also on Individual colors if you want recipes for specific colors, or click on Mixing Your Own Color Palettes if you want to mix a whole palette of colors at one time)

Oil paints in small amounts will give nice color and maintain translucency pretty nicely.  Just keep stirring in a tiny dab at a time until you get the color you want.  If you add too much, though, the polymer will become opaque and not cure as nicely.  It is kind of sticky and stretchy.  Not nice.

Another thing you can use is alcohol inks, which will probably give you a more transparent result.  I just put a small drop on top of a puddle of polymer and let the alcohol evaporate for a few minutes.  Then just stir it up.  If you don't have access to alcohol inks or are just a cheapo like me, you can dissolve Rit dye in rubbing alcohol.  Not quite as good at the store bought stuff, but I've had some pretty nice results.  Just pour in some dye, dump alcohol over top, and shake.  Keep adding dye until you have pretty much saturated the solution(undissolved dye will settle on the bottom).  Then pour off the liquid into a squeezy bottle that seals well.  I use these bottles.  They seem to be doing OK so far.  They dispense nice tiny droplets if you poke a hole with a very fine pin.

thanks for the info guys! I'm gonna try oil paints next time, as I already have some. otherwise I will have to try to get my hands on some alcohol inks. I wonder why food colouring seems to work in thin amounts.

Heres a pic of what orginally happened!



not so great for gummy bears!

Because the amount of water in the added food coloring isn't too great, and also has a better chance to evaporate out a bit before the heat hits the moisture--especially when the liquid clay isn't too deep.  The same is true of other water-based colorants like acrylic paints mixed into polymer clay... a little bit is often fine, but more will usually cause problems.  Leaving the mix out overnight or for at least a few hrs will also allow some of the moisture to evaporate out though, so that's the other factor. And any time water-based items are added to any clays with translucent in them or to translucent liquid clays, the blotchiness will just show up more easily.

That's why we use oil-based colorants (since polymer clay is oil-based) and alcohol-based inks (which can also benefit from sitting awhile but it's not as necessary) rather than water-based materials --oil paints and alcohol inks are also transparent or translucent compared to acrylic paints, for example, which are usually more opaque. 
(Colored powders and other totally dry materials are fine as colorants or inclusions too.)

Hello guys! I have a question, can i use liquid polymer clay in order to make transparent "lentils" like those made from resin? I want to make those so i can glue a photo on the back, but i cannot find resin here, and i have to order diamond glaze from the USA..It will take a month and a half till it gets here and it will be quite expensive.

Not sure why you mentioned the Diamond Glaze in connection with this, or exactly what you're wanting to do, but you can't really get end up with truly clear effect with liquid clay when it's thick (as when poured into a mold, or even in a single layer).  The Fimo brand of liquid clay** (does turn out "pretty clear" even when it's thick if treated right, but would probably not be as clear as you're wanting --check this page for tests and examples:
http://www.garieinternational.com.sg/clay/shop/liquid_polymer2.htm ).

**Liquid FIMO Decorating Gel (Deko Gel, Deco Gel)

Also, when you say "lentils," do you mean actual lentil shapes like the lentil beads made from polymer clay which are two shallow hemispheres joined together, or you do mean something like the small glass "pebbles" to which crafters sometimes glue photos/etc on their flat back sides (usually with E6000 glue), or are you thinking of another shape?

And what size are you thinking of for the pics and/or the clear tops??

This is what i meant, sorry  Grin about diamond glaze, i've seen that you can use DG3 instead of resin, and i also understood that DG3 is the new Diamond Glaze, that's why i mentioned it.
I want to make those little pebbles in a medium size i guess, maximum 5 cm, minimum 2cm.
My point is that i want to use any material that replaces resin, one that is more simple and that is easy to buy (most materials i don't have because i cannot find them in my country and the problem with the ordering from another country is that the shipping costs a lot and most materials are only in USA which is so far away from here  Grin)

Lady Anca, I answered this question in a new thread in the Discussions & Questions board to avoid confusion since it's really a different topic from this original thread and was getting lengthy:
