Whale oil was an important resource during the colonial period and could be used for the following:
- Candle wax: Whale oil was used to make candles, as it burned cleanly and brightly.
- Lamp fuel: It was commonly used as fuel in lamps before the advent of kerosene and electric lighting.
- Soap: Whale oil could be used in the production of soap.
However, whale oil was not typically used as fertilizer. So the correct uses for whale oil from your list are:
- Candle wax
- Lamp fuel
- Soap
