They never dry out. Van Aken Plastalina delivers this permanence with brilliant pigmentation and smooth consistency that improves with use rather than deteriorating. The material remains workable indefinitely, set aside a work-in-progress for weeks and return to find it exactly as you left it.

Sculptors and animators appreciate how readily colors intermix. Blend with ivory or white for tints, black for shades, or combine hues directly to achieve precise intermediate colors. The self-adhering formula builds forms without requiring armature support for smaller pieces, while maintaining enough body to hold detail when tooled. Hand modeling works for broader forms; Van Aken's double-ended tools reveal fine surface articulation.

For production work requiring multiple casts, Plastalina melts at 150°F and pours into molds, a technique model makers use when creating multiples from a master. Individual one-pound bars arrive scored into eight sections for easy portioning. Non-toxic formulation suits educational settings and shared studios. The material's pliability actually improves with age as oils distribute more evenly through repeated handling, making even old stock more responsive than fresh clay from other manufacturers.
