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“.

Step 1: Carving the Plaster / Positive Moulded Part

  1. 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.
  2. 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

  1. The positive mold and a metal part (to form a groove in the glass body) gets placed on a flat table
  2. 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.
  3. Once the plaster has dried, the whole thing can be turned over and planked again.
  4. The second part of the positive part can be fixed.
  5. 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

  1. Once the mould is ready it can be closed to blow the glass body

Step 4: Prototypes & LED Lighting

  1. The groove around the glass body is used for suspension and to integrate the light inside

Step 5: Prototypes

    Very impressive design ................ that can be adapted to glass fusing and slumping using the metal hanging arms to join two "side" panels of slumped glass............. The slumped panels can an additional dimension in variations of height or in this case depth in the hanging view.

    You can't ! You must copy the text then, as you're the editor, you are allowed to delete the message. Finally, create another message where you paste the clipboard and there you can edit. Why making things simple as we can make them complicated ?
