The recycled glass is hand-blown. While the glass is still red hot, it is relaxed over a piece of a teak root then immediately blown into it to form a shape of a bowl/vase. 

The glass cools down, hardens and sits perfectly on top of the root ensuring a perfect fit.

The glass is shaped to suit. The surface of the wood where the glass sits is charred due to the heat of the red hot glass - which adds to the authenticity of the product itself.
