What is Sea Glass?

Before we begin making fake sea glass, let’s first understand what it is. Sea glass is naturally polished glass that has been weathered by the sea and sand. It is common to find it on beaches in various shades and forms, containing green, blue, brown, and white.

It has been smoothed by the ocean’s water, sand, and air and transformed into exquisite jewellery or decorative items. Its smooth, worn surface sparkles like the ocean on a sunny day, and sea glass jewellery is as beautiful as it is rare.vvn

These pieces of glass were discarded and thrown into the ocean and later weathered by the constant motion of tides, waves, and currents. The final product is a clear and rounded piece of glass with a hue that evokes the colour of the ocean.
