At this moment Johan de Vries does not give any demonstrations.
In the centre of the workshop you will find the melting kiln. The glassblower will use a blowpipe to extract a specific amount of red-hot plain glass from this kiln. By adding colour, blowing, shaping and intermittent heating the glassblower will create an unique art object: the unica.
During the blow process, while the glass is red-hot and balancing at the end of the blowpipe, you will receive information about this process.
