We recommend Torben Sode's Book on Anatolian Glass for those of you who wish to know more about the glass melting, forming, and color blending techniques for all these beads. We now offer many styles by specific color in these beads, in addition to assortments. Please appreciate that our glass beads are made from recycled from bottles and jars, melted, and are then handmade by families on small home kilns; different shapes may come from different artisans, and different glass stock will produce different color variations from lighter to darker especially. Colors, sizes, and shapes will always vary. Our photos are only represenstative of one "batch." Used together, however, the variations really enhance the overall look and primitive nature of this product Currently we are having great difficulty in getting product, so it is best to call to go over colors for your needs.
