There is archaeological proof of glass pearls as dating of at least 3000 years. The first examples are from an Egyptian tool fabricated from a form of ceramic no loam) which during cooking produces an aquamarine surface clearly. The ceramic of faience was made from the crushed quartz, from the alkaline sand, from the lime and from the calcite who met and occurred of pigments of copper is known for. Final result did not carry the transparent qualities of the glass pearls which we know today, but the brightness of the surface and the color of the mixture produces a reflective and delicate product which gave glass impression to the modern eye.
When true glass was finally produced (on purpose), wrapped glass pearls were the first to make. Method is simple; glass is heated so as to malleability, envisaged and wrapped around a thread of steel. The thread is coated in a piece of loam who runs to prevent the glass from adhering on the thread while it hardens. Of this point different tools and materials can be used to create various effects such as forms, motives etc. Even small keys of colored glass can be added while the glass is still hot.
molded pearls are very frequent, and today often linked to a weak cost of the hand – by work and products of poor quality. Although it could be true of some producers, there are many very nice pearls produced from the technique of molding. thick glass stems are heated to a well-blended form and introduced into a machine which principally stamps of the glass. A needle pierces a hole in the middle, balls are rolled in the hot sand to soften edges and outside a pearl of molded glass appears. Particularly in the course of the 19th and 20th centuries, the industry of the glass pearl of Boheme was well known for its practice to copy expensive pearls across the process of molding.
