KS _ MG by Meret Probst

At the very base of this glassware project by Meret lies the designer’s fascination with proportion and the way objects harmonise with each other. When designing a collection of products, it is absolutely essential that these things are taken into consideration. Meret has always been a keen drawer and she almost always finds the voice or language of a project through her pen.
Once the design language stands, it needs to be fine tuned and the different parts of the collection are brought to their respective seize and volume. To get a reliable impression of this, Meret builds paper models.
Where traditionally a wooden or metal blowing mould would be made, Meret decided to go for a different option. After experimenting with folded sheet metal, which worked great for the smaller objects, the decision was made to work with reinforced plaster.
For this process, a plaster last (in the exact shape of the glass object) has to be made. Meret used the pattern she already drew up for the paper models to create moulds out of cardboard and tape.
The liquid plaster is poured into the cardboard and left to cure. Once it has hardened, the cardboard is simply cut open and the last is ready to be sanded. Then the last is used to create a classic two-part mould, made out of plaster that is enriched with quartz to give it more strength.
Regular plaster simply breaks under the heat of the glass that is blown into it. Once the mould has completely dried out, it is ready to be blown into. For this, the two halves are clamped together in the right position. The skilled glassblower prepares a bubble of hot glass that roughly fits the proportions of the object. The bubble is inserted into the mould and through blowing gets expanded into the final shape. To get the hot glass into all the corners and edges, it is necessary to create vents for the air to give way to the glass. After the glass comes out of the mould, it is left to cool down very slowly in a kiln. Once this process is over, they are ready to be cut and sanded down to the correct height. The result is a collection of one of a kind objects which can be used in sets or individually. They showcase the material glass in its purest form and focus on the incredible craft behind it.
