Why were potential investors skeptical of kerosene?

Potential investors were skeptical of kerosene primarily due to concerns about its safety and volatility compared to other lighting sources like whale oil or gas. The lack of established infrastructure for distribution and storage also contributed to apprehension. Additionally, early incidents of explosions and fires associated with kerosene further fueled doubts about its reliability and market viability. These factors made investors hesitant to commit to the burgeoning kerosene industry.
