There are many possibilities for glass productions but in the end, it´s about the quality of the mould. You can use wood, graphite, different kinds of metal and of course, each material has its special properties and advantages compared to the others. Usually, wooden moulds are used for tests and small quantities but not all designs are possible here with this material. Metal moulds are used for higher quantities and more stable productions. However, there are glass blowers who only work with wooden molds as for the special and natural appearance of the results and the handmade character you get by using them. We are going to make some tests soon with new high tec materials to enable better surfaces and more stable tolerances for our products. We are curious about the options and results.
