What does the "flame fusion" process create?

The flame fusion process, also known as the Verneuil process, is a technique used to create synthetic crystals from powdered chemicals. In this method, powdered materials such as alumina (aluminum oxide) are introduced into a high-temperature flame. The intense heat melts the powder, which then solidifies and forms a crystal as it cools. This process allows the production of synthetic gemstones that can imitate the properties of natural stones, making them sought after for various applications in jewelry and other decorative purposes.

Flame fusion specifically thrives on its ability to create high-quality, transparent synthetic gemstones at a much lower cost than their natural counterparts. This method has been widely used to produce rubies and sapphires, among other gemstones, contributing significantly to the market for synthetic alternatives. Understanding this process is crucial in the colored stone industry, as it helps identify and differentiate between synthetic and natural stones.
