Throwing Eco Forma: A Different Rhythm at the Wheel
Eco Forma can be thrown on a pottery wheel, but it should be worked according to its own material rhythm. Its softness, responsiveness, and thixotropic movement create a fluid experience under the hand, while controlled pauses allow the form to settle as it develops.
The most reliable approach is simple: use minimal water, apply steady pressure, build height gradually, support the form carefully, trim before the clay fully sets, and dry completely before continuing through the Eco Forma System.
1. A Different Rhythm at the Wheel
Eco Forma is soft, responsive, and thixotropic. It moves readily under the hand, then begins to settle as movement slows.
At the wheel, this allows the clay to center, open, and take shape with relatively light pressure. It responds best to a calm, gradual approach rather than speed or force.
Eco Forma is not intended to behave exactly like kiln fired stoneware or porcelain. Its wheel character comes from softness, minimal water, controlled movement, and an air cure ceramic process that continues beyond throwing.
2. Use Less Water
Eco Forma generally requires less wheel water than traditional ceramic clay.
Begin with damp hands rather than a flooded bat. Add water only when surface drag prevents the clay from moving cleanly, and use the smallest practical amount at each stage.
Too much water can:
- Make the wall overly soft
- Reduce height and control
- Weaken the lower wall
- Encourage the base to move on the bat
- Prolong drying
- Increase distortion during removal
When the surface becomes overly glossy, slippery, or unstable, remove excess water and pause. A lighter water approach preserves the clay’s body while allowing its natural responsiveness to do the work.
3. Center With Steady Pressure
Eco Forma responds well to steady, even pressure during centering.
Brace your hands and let the clay move gradually rather than forcing it into place. Because the material is soft and responsive, a small adjustment can create a visible change. Controlled pressure is more useful than speed.
Once the clay is centered, pause briefly and allow it to settle before opening. Confirm that the base remains secure and that the clay turns without a visible wobble.
4. Open Gradually
Open the centered clay with light, controlled pressure.
Leave enough material for the intended base thickness and widen the opening gradually. Avoid pushing too deeply or too quickly. Eco Forma responds readily, so measured movement gives you greater control over the floor, lower wall, and final shape.
Remove pooled water before lifting the walls. Pause when needed and let the clay settle before widening or pulling further.
5. Build Height in Stages
Eco Forma responds best when height is developed gradually.
Establish an even lower wall before pursuing height. Support the wall from both inside and outside, then use repeated, controlled pulls rather than attempting to raise the form in one aggressive movement.
Release pressure gradually as you approach the rim. Pause briefly between pulls and remove excess moisture before continuing.
This staged approach helps maintain even thickness and reduces strain while the clay is still soft. Stop adding height when the wall no longer regains stability after a pause.
6. Keep the Form Compact
Eco Forma performs most reliably at the wheel in smaller forms with balanced proportions.
Compact vessels, bowls, cups, cylinders, and related forms allow the clay’s softness and responsiveness to work with greater control. Taller, wider, or more projecting forms may require slower development, additional support, reduced water, or time to firm between stages.
Working within the clay’s natural scale helps preserve wall strength and gives the form a clearer path through removal, drying, Dip, Ceramic Coat, and finish.
7. Remove and Support the Form Carefully
Once the form is complete, remove visible water from the interior and around the base. Allow the piece to rotate briefly without pressure so the wall can settle, then inspect the form from more than one direction.
When the clay is ready to move:
- Use a clean cutoff wire beneath the complete base.
- Keep the wire low and level.
- Support the base during transfer.
- Move the piece to a clean, dry, nonstick surface.
- Avoid lifting or carrying the form by its rim.
- Preserve the round shape without squeezing the walls.
When immediate removal would distort the form, allow it to firm briefly on a removable bat or supported wheel surface before transferring it.
8. Trim Before Set, Refine After Drying
Complete major trimming while the clay is firm enough to hold its shape but not fully set.
At this stage, Eco Forma can be refined with light, controlled tool work. Establish the foot gradually, preserve adequate base thickness, and stop when the tool begins tearing or dragging rather than cutting cleanly.
Once the clay has fully set, avoid aggressive wheel trimming. The surface may tear instead of cutting cleanly. Allow the piece to dry completely, then use Dip as the next controlled refinement stage.
Dip reinforces the dry form, reduces powdering, and supports light edge, foot, rim, or surface correction before image, color, Ceramic Coat, and finish.
Using Paper to Balance Early Drying
A clean piece of paper may be placed gently over the opening before the form is transferred from the wheel. This can help slow moisture loss from the exposed rim and upper wall while the base remains wetter.
The paper should rest lightly. Do not allow it to adhere to a wet rim, collapse into the form, trap standing moisture, or leave fibers on the clay. Remove or adjust it as the piece firms so the interior and exterior can continue drying evenly.
This moisture balancing method should be tested on the intended form and drying conditions.
9. Dry the Thrown Form Evenly
Place the transferred form on a clean, dry, stable support that preserves its geometry.
Allow air to reach both the interior and exterior. Check the rim, walls, base, foot, and any thicker areas separately. The base will often dry more slowly than the upper wall, so a dry feeling rim does not prove that the whole piece is ready.
Turn, elevate, or reposition the form only when it can tolerate the movement without distortion. Avoid strong direct airflow, direct heat, freezing, and rapid one sided drying.
Do not move into Dip while the form feels:
- Cool
- Damp
- Darker in thicker areas
- Rubbery from moisture
- Noticeably heavier than expected
- Different from one side to another
The entire form must be fully dry before the next stage begins.
10. Continue Through the Eco Forma System
Once the thrown form is fully dry, it can move into Dip for reinforcement, refinement, and surface preparation.
Form → Dip → Image / Color → Ceramic Coat → Finish
Dip should reach all required surfaces, including the exterior, interior, rim, base, foot, and any attachment areas. Drain the piece thoroughly and prevent material from pooling inside the form.
After Dip has dried completely, color, drawing, transfer, painting, and mixed media can develop across the prepared surface.
Ceramic Coat builds and unifies the matte ceramic surface. Gloss Top Coat may then be used when the design calls for greater clarity, depth, and reflected light.
Throwing begins the form. The Eco Forma System carries it through surface and finish.
11. Best Uses and Thoughtful Limits
Eco Forma is best suited to smaller thrown forms with balanced walls and compact proportions.
Its softness and thixotropic response support direct movement at the wheel, but taller, wider, or more demanding forms may require:
- Slower development
- Less water
- Additional support
- Short pauses between pulls
- Time to firm before further shaping
- Separate testing before repeating the form
Use minimal water, build height gradually, trim before the clay fully sets, and allow the entire piece to dry evenly before moving into Dip.
Eco Forma offers a distinct air cure throwing process. It should be worked according to its own rhythm rather than treated as a direct substitute for kiln fired stoneware or porcelain.

Pressure: Use steady, even movement rather than force.
Opening: Work gradually and protect the base.
Pulling: Build height through measured stages with pauses between them.
Scale: Begin with compact, balanced forms.
Removal: Support the base and avoid lifting by the rim.
