Inside the Race to Save the Clay Behind ‘Wallace & Gromit’ | WSJ

Why It Matters

The clay shortage threatens Aardman’s ability to produce its iconic stop‑motion films, illustrating how fragile supply chains can endanger cultural brands and prompting studios to secure alternative sources.

Key Takeaways

• Aardman relied on New Plast's proprietary clay for decades.
• Supplier's retirement threatened studio's ability to produce stop‑motion.
• Aardman stockpiled and experimented with self‑mixed clay to survive.
• New Plast’s recent sale to Hugh revived the essential material.
• Clay remains core to Aardman's identity and future productions.

Summary

Wallace & Gromit’s home, Aardman Animations, faces a supply‑chain emergency as the New Plast company that has manufactured its signature stop‑motion clay for more than 25 years announces retirement.

The studio, which uses only a specific terra‑cotta, wax‑free formulation, discovered its reserves were dwindling and quickly began hoarding existing stock while engineers attempted to replicate the material in‑house, mixing pigments and chalk to match the exact consistency required for puppets.

A senior technician recalled the CEO’s urgent email and a father‑in‑law’s horrified question, “What are you going to do?” – underscoring the panic. He later described the tactile process: “If it’s too soft, I add five, six, seven percent chalk,” and praised the new acquisition by Hugh, which restored the supply line.

The episode highlights how a single niche supplier can jeopardize a studio’s creative pipeline, reinforcing the strategic value of material continuity for Aardman's brand and prompting broader industry discussions about diversifying critical artisanal inputs.

Original Description

For decades, the animators behind “Chicken Run” and “Wallace & Gromit” have used a very specific type of clay. It’s pliable enough to reshape for months, but firm enough not to melt or crack under studio lights.

Then one day, Aardman Animations got word that its clay manufacturers were retiring. News that the studio's clay supply was in jeopardy spread quickly from newspapers to Reddit fan forums.

The Journal’s video goes inside the legendary film studio to show how it raced to save its beloved clay.
