The project approach was to design a glass luminaire that makes optimum use of the properties of the glass and does not restrict itself to traditional „bulb packaging“.
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Carving the Plaster / Positive Moulded Part
- The shape of the glass body to be blown must first be carved out of plaster. To do this, pour out a block of plaster in the desired size and mould it until the mould is finished.
- It is important to brush them afterwards with shellac. This is done in order to prevent the plaster from sticking together when building the mould, where new plaster is applied.
Step 2: Building the Mould
- The positive mold and a metal part (to form a groove in the glass body) gets placed on a flat table
- It is important to form the positive mould and to seal it all around. The plaster can then be poured over the positive part until it is covered up to 5 cm above the highest point.
- Once the plaster has dried, the whole thing can be turned over and planked again.
- The second part of the positive part can be fixed.
- Then the plaster can be poured over for the second half of the mould. Again until it is completely covered and up to 5 cm higher than the highest point.
Step 3: Glass Blowing
- Once the mould is ready it can be closed to blow the glass body
Step 4: Prototypes & LED Lighting
- The groove around the glass body is used for suspension and to integrate the light inside
