What material is recommended for optimizing solar energy transfer during the sun tea steep?
Answer
High-quality, clear glass containers.
When preparing sun tea, the effectiveness of the process relies on maximizing the transfer of solar energy into the water to facilitate steeping. For this reason, selecting high-quality, clear glass containers is recommended. Glass allows for the maximum penetration of light energy. While plastic might absorb some heat, clear glass ensures that the solar radiation directly affects the water volume inside the vessel, leading to the most effective solar energy transfer possible within the constraints of the method and optimizing the steep time relative to the available sunlight.
