Polystyrene Half-Sphere
Rounded support for dummy domes and baked Alaska shapes, to be covered before display.
The Polystyrene Half-Sphere is a rounded support used to reproduce a dome, a baked Alaska, or a foam piece for demonstration or display purposes, without using an actual preparation. It is available in 7 diameters, from 4 cm to 10 cm.
Features
- Available diameters: 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm
- Lightweight material, easy to work with and assemble
- Reusable support for multiple demonstrations
Uses and occasions
Use this half-sphere to present a dome or baked Alaska model in a display case, during training, or to test a decoration before reproducing it on an actual preparation. Two half-spheres of the same diameter can be assembled to form a complete sphere. Cover the support with fondant for a finished look, or paint it for a strictly decorative presentation.
Please note: this half-sphere is a non-edible polystyrene support. It does not replace a food-safe mold and must never come into direct contact with a preparation intended for consumption. For a demonstration or display, cover it with fondant or wafer paper. For a real baked Alaska or edible mousse dome, use a dedicated food-safe silicone mold.
Frequently asked questions
Can this half-sphere be used to prepare a real baked Alaska?
No. It is a non-edible polystyrene support intended for demonstrations or display only. For a real baked Alaska, use a food-safe silicone mold.
How do you assemble two half-spheres into a complete sphere?
Choose two half-spheres of the same diameter, lightly sand the edges if necessary for a clean fit, then secure them with a small amount of glue or moistened fondant before covering the entire piece.

Diameters 4 to 6 cm are suitable for individual pieces or decoration tests, while diameters 7 to 10 cm are suitable for main display pieces or group presentations.
