Glass Hanging Solar Radiometer with Hook and Peak

£ 21.99
This Solar Radiometer has a clear glass globe and hangs from a hook made from crystal glass. The Solar Radiometer is made by traditional Thuringian hand-blowing in Germany, from Lauschaer bottle glass. The Crookes radiometer was invented by the chemist Sir William Crookes as the by-product of some chemical research. In the course of very accurate quantitative chemical work, he was weighing samples in a partially evacuated chamber to reduce the effect of air currents, and noticed the weightings were disturbed when sunlight shone on the balance. Investigating this effect, he devised the device named after him, still manufactured and sold to this day as a curiosity item. This version is both a scientific curiosity and a beautiful ornament
