Many cold porcelain figures, dolls and animals, all start by modeling a basic cute head and then adding the eyes, expression, hair, etc to create the character (such as the doll shown above). This 'basic cute head' tutorial was originally published in a Portuguese magazine and I have done my best to translate the instructions into English for those that cannot read the Portuguese. .
Materials needed are some cold porcelain paste (or other soft air-dry-clay) and a Styrofoam ball. Tools used are your fingers, a cutting tool, a crochet hook and a ball-end tool. The first step is to tint your clay/cold porcelain a peach tone or other flesh tone unless your prefer tinting or painting after it has cured.
Next, wrap the Styrofoam ball in clay or cold porcelain (CP). Select enough CP paste to completely cover the foam ball (approximately 2" ball shown here). Press the foam ball into the CP and shape the CP around it
Close any gaps that appear as you wrap the CP so that you completely enclose the foam ball inside. Avoid trapping any air.
With the palms of your hands, smooth and shape the CP into an egg shape. Using your thumbs, enhance the curvature of the nose and forehead.
Refine the shape of the head and pull some of the clay into a neck.
With a crochet hook, push the CP paste from the bottom up and then form the nose with your fingers
.....leaving a pointed nose shape.
Strengthen the shape around the area of the eye with your thumb. Add nostrils.
To mark the mouth, envision an imaginary line that creates a cross between the nose and neck and from one cheek to the other cheek. Where the imaginary line crosses, insert the tool straight in to form a mouth.
(note: The numbering of photos in original tutorial skipped #4...it's not missing)
With the end of a crochet hook, create a diagonal crease in each corner of mouth.
Using the diagonal mark as a guide, use your thumb to lift the cheek and indent the chin, smoothing down toward the neck.
With the small end of a ball-end tool, shape the lower lip....running tool from one side to another.
Define the corners of the mouth by dimpling with large end of ball-end tool.
With smaller end of ball-end tool, create small mark on top of the upper lip.
Ears ... create 2 ears and glue onto the head of the doll. Shape 2 equal amounts of CP into 2 small ovals. Roll between fingers to indent slightly. Attach an ear to each side of head using round-end tool to apply pressure to center of ear.
