What you'll need:
White Polymer clay (I prefer to use Premo! as it is a bit sturdier after baking)
Liquid Sculpey or Liquid Kato (I used Kato)
Brayer or acrylic rod
You will need to condition about half of a block of clay. After your clay is conditioned, run it through on the widest setting.
Then fold it in half.
Next, create your texture! A really thick texture will make the coloring more interesting.
Next, use your cutters in whatever shapes you want
Poke holes if necessary (I'm using mine for a necklace and earring set, so I needed holes).
Then, bake at whatever setting is recommended for your clay type. For this project, I ended up using a little bit of pearlized white mixed with regular white, and since the pearlized white tends to burn, I baked at a lower temperature. Also, if you are baking on a metal pan, the parchment paper will keep the bottoms from discoloring.
While your stars are baking, you can pour some liquid clay, and mix in a few drops of ink. Let the alcohol evaporate a little bit.
Once your starts are done baking, you can use a blade to scrape off any imperfections (if necessary), and then using a small paint brush or your finger (with a GLOVE), apply the clay-ink mixture to the top of your clay piece. I recommend leaving them on the same baking pan so that the liquid clay doesn't run while you are moving the pieces.
Then bake again for 5 minutes or so, and voila! You have faux ceramic!
A couple of things to note: I almost always wear latex gloves while working with polymer clay. This is for 2 reasons - I don't want to have to sand off finger prints, and I really don't like the way it makes my hands smell. It's just a personal preference, but I highly recommend them for when you are working with the alcohol inks - those can really stain!
I used this same technique for these ornaments:
