Preparation
Step 1
Preheat your oven to around 200-250°C.
Step 2
Spread a very thin layer of bicarbonate in the dish. Use a spatula to distribute it evenly.
Step 3
Place the dish in the hot oven, stirring lightly at regular intervals to ensure even cooking.
Keep a close eye on the bicarbonate in the oven, as it must not burn.
Step 4
After a few minutes, air bubbles appear, wait for them to disappear and remove the dish from the oven.
This is sodium bicarbonate, which breaks down into sodium carbonate (Na₂CO₃) and releases carbon dioxide (CO₂).
Step 5
Soda ash is ready!
Once the powder has cooled, store in a cool, dry place out of the reach of children and pets.
