Imposing cracked glass mortar

Beautiful glass mortar and pestle. Very design, signed but difficult to read the name of the creator... Maybe b. Ruotha. The mortar is made of cracked glass and the pestle has a green/duck blue inclusion in the center. Very nice pieces. Count about 4 kilos for the whole. About 22cm wide and 10cm high. This piece can be diverted into a photophore, very beautiful color schemes thanks to the effects of glass.
