This purple 2-ply polyester non-medical face mask, featuring a filter pocket on the inside, comes in two sizes (measurements below). The design on the front is of the flames of different elements. Perfect for chemistry teachers doing flame tests! Different elements burn with a different coloured flame – here’s some cute examples with some of their element’s characteristics.
Elements represented are strontium (red flame holding glow sticks), calcium (orange flame with visible skeletal bones), sodium (yellow flame thirsty having a drink), boron (green flame lifting weights), arsenic (blue flame, dead holding a bottle of poison) and potassium (purple flame holding a medical kit).
The Small/Medium size (10.8cm x 16cm) is recommended for older children, and the Medium/Large size (13cm x 18.5cm) for adults.
