How Does Temperature Affect the Color of Seashells?

Constant Temperatures are Best

Seashells have fascinated people since the dawn of human history. Found in many shapes and sizes, shells have served as money and also decorative items. Today they are often used to spruce up gardens.

Because they come from marine environments that feature relatively stable conditions, settings with near-constant temperatures are preferred for maintaining the vibrant colors of seashells.

Keep Out of Direct Sunshine

Even more important than temperature, prolonged exposure to direct sunshine causes the colors of many seashells to fade.

Look for shady areas if you want to preserve the colors of seashells used in wind chimes or as other decorative outdoor features.

Avoid Dust and Moisture

Besides maintaining consistent temperatures away from direct sunshine, limiting the amount of moisture and dust will keep seashells looking colorful and shiny.

An Acrylic Coating is Another Option

Since it is not always possible to maintain constant temperatures or keep seashells in your garden out of direct sunlight, another option is adding an acrylic coating. This step will prevent changing temperatures and other environmental factors from dulling the colors of your most precious seashells.
