They are manufactured using yellow Sodocalcique glass with a diameter 6-7 mm. Red liquid filling (mercury free) They feature a special ring/hook that can be clipped on the glass, patented by Alla France. They possess an expansion chamber to support temperatures higher than those of the thermometer.
The graduation is printed and fused in the glass with a special process. The graduation resists to all chemical products except fluoridric acid and hot soda (to a lesser extent) because these 2 products attack the glass. Even if you can feel a relief when touching the graduation, the thermometer is not engraved.
