How to make small fired pottery ware ?

Make an approximate shape by hand. Let slightly dry, and re-shape while it starts drying, until you get the shape you want.

Smoothe with your fingers or with a knife, and maybe create relief by applying some cloth, a leaf or a vegetal weaving.

Before it's too hard, pierce the holes with a straw or a hand-powered metal drill.

Start a fire in a stove, or outdoors. Put the objects near the fire to entirely dry them.

Many cooking techniques are available. You can simply put the objects in the fire, or on the embers. The shades will be variable. Be careful: once the fire is finished, wait until it’s completely cold before you take the objects!

Test: place the objects in water. Il they are well fired, they will note disintegrate. If they do, the next firing should be longer and/or reach a higher température.

Another technique, firing without oxygen. Enclose the objects among green stuff, or wood dust. The objects will be black.
On the photos, pine needles are stacked around a cardboard tube in a small metal box (1). The cardboard is then replaced by a pile of small bits of pine needles (at the bottom, non visible), a bead (2), small bits of pine needle (3). The lid closes the box (4). The resulting bead is black (5).

On the contrary, firing with an excess of oxygen doesn’t produce the grey and black shades resulting from a lack of oxygen. Here the objects lay on the bottom of a pot, and the pot is placed on embers.

The final colour will be the colour of fired clay, and of course it depends on the type of clay.

Another technique, producing uncertain results at a domestic scale, consists in painting the objects, before they are totally dry, with a thin mud added with thin powders: ashes, very fine clay (from successive settlings, it gets more and more fine), yellow-orange washing liquid from rain falling on clay containing iron, etc. All trials are possible !
