Glass vessels, open mould object, jewellery; Willem van Oijen is versatile and highly skilled in the making of glass art. The surface of each of the objects he creates, whether it is blown or cast - a flat panel or a block, is penetrated and reshaped by deep relief sand-carving - wheel cutting - grinding -engraving - etching and polishing. By adding other materials to the object like bronze steel or wood in combination with the glass component he accentuates the transparency and fragility of the glass. An important aspect in his work is that he creates an interaction between opposites in the way the surface of an object is worked, the use of colour, the difference in radiance of the materials used, the concept and design. The use of contrasts creates tension in his work, a tension carefully balanced, consequently resulting in homogeneous but strong objects of art.

The artist received his education from his father, Willem van Oijen sr., who was a renowned glass artist, painter and sculptor in the post war era. You can fairly say that Willem van Oijen jr. was born and raised with glass.
