Lucite, or acrylic, is a popular material for mid-price pens. It's a very tough and hard material that is transparent in its natural state, so it can be mixed with all kinds of colorings for some truly distinctive effects. It can be cast into shape, reducing the amount of hand labor required for finishing. Today’s acrylic-blank makers have become very skilled at achieving the kind of unusual coloring in acrylic molding that was more typical of the early celluloid style of the 1940s.
Lucite was first marketed by DuPont in 1937. This synthetic material that is denser and heavier than normal plastic and is usually finishes without the seams and knobs that are tell-tale signs of injection or molding. Like Bakelite, it is a thermo set plastic. Although in its original state it is clear and colorless, it could be tinted any color of the rainbow, from transparent to opaque. When placed briefly in hot water, Lucite is odorless. Higher-end pens are often made with Italian Lucite. As with anything you need to properly take care of your plastic pens. Older Lucite can develop cracks from age or exposure to heat.
