🧪 Everyday Chemistry
Ash, fat, bark, limestone, and sand — with fire, ordinary things transform into soap, glue, mortar, leather, light, and glass.
Make glue and pitch
Melt tree resin with charcoal dust into a strong glue that sets hard and a black pitch that seals leaks.
Make lye from wood ash
Drip water slowly through hardwood ash to draw out a strong cleaning liquid — handle it with care, it bites skin.
Make soap from fat and lye
Cook fat and lye together — carefully — until they become the soap that keeps your whole village healthier.
Burn limestone into lime
Roast crushed limestone or seashells white-hot in the kiln, then wake the lime carefully with water — it gets hot and it bites.
Mix mortar, plaster, and whitewash
Blend lime with sand and water to glue stones together, seal walls smooth, and paint rooms bright and clean.
Tan a hide into leather
Scrape a skin clean, soak it in crushed-bark water for weeks, and work it soft into leather that lasts years.
Make lamps and candles
Float a wick in a dish of fat, or dip a wick again and again into melted fat or beeswax, and push back the dark.
Melt sand into glass
In your very hottest furnace, sand with plant ash and lime melts into glass for beads and small vessels.
