What if you could capture the elegance and feel of ivory – without harming animals? Elforyn delivers that promise: authentic appearance, excellent machinability, durable and stable. Elegant pens, knife handles, inlays – all with peace of mind.
Explanation Text
Elforyn® is a modern, high-grade material engineered to replicate the appearance, texture, and aura of natural ivory. Instead of using tusks or other animal-derived sources, it’s composed of a blend of mineral base materials bound in a light-stable resin, delivering color permanency and ethical production.
Key Features and Production
Elforyn is a mineral–resin composite that is resistant to yellowing and stable under UV light. It has very low water absorption and excellent thermal behavior, which means it can even be heat-formed in boiling water. The surface is hard and abrasion-resistant, while still allowing smooth processing by grinding, milling, drilling, turning, and polishing.
Mechanical and Physical Properties (Super Tusk variant)
- Density: approx. 1,200 kg/m³
- Hardness: ~80 Shore D
- Tensile strength: ~46 N/mm²
- Elongation at break: ~15 %
- Flexural strength: ~88 N/mm²
- Flexural modulus: ~1680 N/mm²
Look and Feel
Elforyn can be finished to either a matte or high-gloss surface and can even be lacquer-coated. Under certain lighting conditions it produces translucent and fluorescent effects, adding visual depth similar to natural ivory. The premium “Super Tusk” version goes even further, offering Schreger lines and subtle color variations that make it one of the most authentic ivory substitutes available.
What are Schreger Lines?
Schreger lines are the distinctive cross-hatched patterns that appear when natural elephant ivory is cut in cross-section. They are formed by the microscopic tubules of dentin within the tusk, which are arranged in layers and set at alternating angles. This structural layout creates the characteristic intersecting patterns. The angle of these intersections – typically between 115° and 135° – is even used by experts to distinguish elephant ivory from mammoth ivory. Schreger lines are essentially nature’s fingerprint for ivory, and one of the main reasons why the material fascinated artisans for centuries.
Applications
Elforyn has a wide range of uses: pen blanks and fine writing instruments, knife handles, jewelry, decorative inlays, musical instruments (such as keys or ferrules), as well as restoration and art objects.
Ethics and Durability
Elforyn avoids the ethical issues associated with natural ivory. It is resistant to oils, fats, mild acids and bases, and remains dimensionally stable over time. This makes it not only environmentally and ethically sound, but also highly suitable for long-lasting craftsmanship.
