Kit of 6 flexible polymer clays in pastel shades (6 x 227 g). Oven cures at 135 °C. Flexible and resilient after baking, no shrinkage.
CosClay Pastel Six Colours is a kit of six hybrid polymer clays in pastel shades formulated to remain flexible and resilient after oven curing at 135 °C. Unlike conventional polymer clays, CosClay does not break or crack after baking, making it the go-to choice for sculptors, animators and artists working with delicate, articulated or thin-walled pieces. Each kit includes six 227 g blocks in Pink Rose, Orange Blossom, Mellow Yellow, Green Tea, Butterfly Blue and Lilac Mist.

What it is used for
CosClay Pastel is designed for artistic and technical projects where post-cure flexibility is essential. Its ability to reproduce fine details without risk of breakage makes it especially valued in professional productions and precision craft work. The pastel shades in the kit make it easy to differentiate pieces and blend colours without the need for additional pigmentation.
- Characters and dolls for stop motion animation
- Articulated figures and puppets with moving parts
- Collectible miniatures with fine details
- OOAK (One of a Kind) sculptures and artist figures
- Dioramas and scenography with fragile or thin-walled elements
- Props and accessories for character design and special effects
- Decorative pieces and handcrafted jewellery
- Architectural models and detailed scale modelling
How to use it
- Condition the clay: work the block with your hands for a few minutes to soften it and make it more manageable. If it is very cold, leave the block at room temperature for 10–15 minutes before starting.
- Sculpt the piece: work with your usual tools. CosClay accepts needles, spatulas and loop tools. Its hybrid texture allows you to work fine details without the material sticking excessively to the tools.
- Blend colours if needed: you can combine the six shades with each other to obtain new tones. The blend is uniform and leaves no streaks if the material is worked properly.
- Add internal supports if necessary: for articulated or long pieces, incorporate wire or rod as an internal armature before baking.
- Preheat the oven: set to 135 °C. Use a separate oven thermometer to verify the actual temperature; domestic ovens can deviate by up to 15–20 °C.
- Bake the piece: place the sculpture in the oven and bake approximately 15 minutes per 6 mm of thickness. Do not exceed 150 °C to avoid surface scorching.
- Allow to cool: remove the piece and let it cool to room temperature before handling. The material reaches its final strength once cold.
- Finishing: once cured, the piece can be sanded, painted with acrylics, varnished and finished using standard sculpture techniques.
Tips for use
Temperature control during baking
Temperature accuracy is the most critical factor when curing CosClay. An oven that is too hot will scorch the surface while leaving the interior uncured; too cool and curing will be incomplete, leaving the piece brittle. Always use a probe or infrared oven thermometer to verify the actual temperature before placing the piece inside. If baking in a convection oven, reduce the time slightly compared to a static oven.
Working with armatures and articulated pieces
CosClay is particularly well suited to articulated figures thanks to its post-cure flexibility. For joints, build the armature with aluminium or stainless steel wire before applying the clay. Thin parts (fingers, tails, ears) can be baked without an armature if the thickness exceeds 3 mm, but below that threshold it is advisable to reinforce them. Once cured, the joints can be moved repeatedly without the clay cracking.
Colour blending and surface finishes
The six pastel shades in the kit are formulated to blend easily with each other. To achieve more saturated colours or add darker tones, you can mix CosClay Pastel with CosClay Sculpt Medium Firm Gray. Before painting the cured piece, a light sanding with fine-grit sandpaper (400–600) improves the adhesion of acrylic paints and removes any surface fingerprints.
Frequently asked questions
What is the difference between a conventional polymer clay and a flexible hybrid clay?
Conventional polymer clays cure in the oven but the result is rigid and can chip or break on impact. CosClay is a plastic/rubber hybrid clay that, after curing at 135 °C, retains significant flexibility. This means that thin parts withstand bending and twisting without fracturing, which is especially important in articulated figures or stop motion animation.
Can it be baked more than once?
Yes. CosClay supports multiple bakings. You can cure one part of the piece, add more raw material on top and bake again. This technique is common when working on figures in sections. Always keep to 135 °C and control the time according to the thickness of the new area.
Can it be mixed with other polymer clays?
Yes, CosClay is compatible with other oven-cure polymer clays such as Super Sculpey Beige or Super Sculpey Firm Gray. Blending allows you to adjust the firmness and flexibility of the resulting material. Keep in mind that mixing with conventional clays will make the final result less flexible than pure CosClay.
At what exact temperature should I bake it and for how long?
The recommended temperature is 135 °C. The standard baking time is 15 minutes per 6 mm of piece thickness. For very thick pieces, it is preferable to bake in several stages rather than increasing the time in a single baking, as prolonged excess heat can yellow the lighter shades.
Does CosClay inhibit the curing of platinum silicones?
Polymer clays can contain components that inhibit the curing of addition (platinum) silicones. Before pouring platinum silicone over a CosClay sculpture, always perform a contact test: apply a small amount of silicone to the surface and check that it cures correctly. If inhibition occurs, seal the piece with lacquer or shellac before moulding. Condensation (tin) silicones do not present this problem.
Can the piece be painted once cured?
Yes. Once cured and cold, CosClay accepts acrylic paint, water-based enamels and varnishes. To improve paint adhesion, lightly sand the surface with 400–600 grit sandpaper and wipe away the dust with a dry cloth before painting. The pastel shades in the kit provide a built-in colour base that can be used as-is or as an undercoat for paint layers.
What should I do if the clay is too hard to work with?
If the block is very cold or hard, leave it to rest at room temperature for 15–20 minutes. You can also soften it by working it between your palms or holding the block under a heat lamp for a few seconds (not minutes). Avoid the microwave, as uneven heating can trigger unwanted partial curing.
Is it suitable for children or does it require adult supervision?
CosClay is a material aimed at professional and semi-professional use. The baking step requires adult supervision and correct oven use. The raw clay is safe to handle, but the curing process involves elevated temperatures that must be managed with care. It is not recommended for use by children without direct adult supervision.
