What is FIMO actually? Everything you need to know about the popular, colourful modelling clay from STAEDTLER
Users often talk about “FIMO dough for kids” or “FIMO playdough for kids” – but FIMO is a modelling clay. FIMO modelling clay is a well-known and popular choice for children, amateur artists, DIY crafters and professional users of all ages. But what is FIMO and why is this modelling clay so popular? In the following, we will explain where FIMO comes from and what the material is made of. We will also reveal the special product qualities that characterize this versatile clay.
FIMO was the first modelling clay that could be hardened in the oven. The clay was developed in the mid-20th century. Back then, world-renowned doll maker, Käthe Kruse, set out to develop a suitable clay that could be used to model dolls’ heads with as much detail as possible. But the material she invented was not yet suitable for serial production.
Her daughter Sophie Rebinder-Kruse achieved the breakthrough in the year 1939. She continued experimenting with the clay by incorporating various pastes and bright colours into the materials. Then she started modelling all sorts of things, such as vases, toys and figures. This world-famous modelling clay owes its name to Sophie Rebinder-Kruse: Her nickname “Fifi”, combined with her passion for mosaic work, led her to create the name “FIMOIK”. In 1954, Sophie developed the first modelling clay sets.
Later, in the year 1964, Eberhard Faber acquired all rights to the colourful modelling clay and gave it the name “FIMO” in 1966. Since 1978, FIMO has been owned by STAEDTLER – first under the brand Eberhard Faber, and since 2009 under the umbrella brand STAEDTLER. There, the FIMO concept was developed over the years and refined with optimised formulas. As a result, more colours and impressive effects have been added to the standard FIMO products over time. In 2016, the modelling clay celebrated its 50th birthday.
In 2010, another type of modelling clay was introduced: the air-drying FIMOair. This modelling clay is a separate type of clay made from kaolin (natural, basic) and offers an ideal supplement to the range of modelling clays. However, FIMOair cannot be mixed with oven-hardening FIMO and cannot be hardened in the oven.
For reasons of preventive consumer protection, STAEDTLER has avoided the use of phthalate-based plasticizers in FIMO oven-hardening modelling clay since 2006. Oven-hardening FIMO modelling clay is made of:
- Plastic powder (PVC)
When hardening in the oven, the plastic powder contained in FIMO sets and forms a firm solid after cooling. Compared to “normal” modelling clay, the material is significantly firmer. The structure of FIMO professional, for instance, makes it possible to model small and finely detailed objects. The wide variety of colours available for the product are created by adding various bright colour pigments to the modelling clay.
- FIMO can be hardened in the oven at 110 degrees Celsius. The maximum temperature should not exceed 130 degrees.
- Already hardened FIMO elements can be placed in the oven again when applying techniques that require multiple hardening processes.
- All oven-hardening FIMO types are mixable with one another.
- The hardened modelling clay can be varnished with special FIMO paints or painted with suitable pens or acrylic and oil paints.
- FIMO can be sanded and polished.
- Holes for FIMO jewellery and beads can either be made with a needle before hardening or drilled with a hand drill after hardening.
- Broken FIMO parts can be easily attached again using two-component adhesive.
- If you would like to produce arched FIMO elements, oven-proof moulds can be used to support the material.
- FIMO should only be washed by hand, not in dishwashers, since dishwashing liquid is too aggressive and can harm the material.
- To ensure that opened FIMO blocks don’t collect dirt or dust, we recommend storing them in aluminium foil or PE bags in a cool and dry place. Avoid contact with polystyrene, PVC and styrofoam.
- FIMO that has become too hard can be kneaded until soft again using Mix Quick softener.
- In contrast to FIMO, FIMOair dries in the air.
- FIMOair is an ideal choice for art, spare time and hobbies as well as for pedagogical purposes in schools, kindergartens and similar institutions
- Packaging in film prevents the clay from drying out
- Hardened models (basic & clay) can be finished (filing, polishing, drilling, painting, varnishing)
- Hardened models (light) can be finished (painting, varnishing)
- FIMOair is ready for immediate use
