Key Differences
Modeling Clay and Polymer Clay are both essential materials in the world of arts and crafts. While both can be shaped and molded, their composition and uses differ substantially. Modeling Clay is primarily oil-based, ensuring it remains soft and pliable. In contrast, Polymer Clay consists of polyvinyl chloride (PVC), which hardens upon baking.
Modeling Clay is often used for creating temporary forms or sculptures that won't be exposed to high temperatures, given its inability to harden like its counterpart. Polymer Clay, however, is a favorite for artists and crafters looking to create permanent and intricate designs, given its durability post-baking.
Another key distinction between Modeling Clay and Polymer Clay is their finish. Modeling Clay tends to have a more matte and earthy appearance, resembling natural clay. On the flip side, Polymer Clay can be found in a variety of colors and finishes, from matte to glossy, making it versatile for jewelry and decorative items.
When handling these clays, their texture differs. Modeling Clay generally has a heavier and waxier feel, while Polymer Clay is lighter and can be conditioned to achieve a smooth consistency.
In summary, while Modeling Clay and Polymer Clay might seem similar at a glance, their properties and uses are distinct. One remains soft and workable, while the other can be baked to a hard finish, each catering to different artistic needs.
