Alabaster is not recommended for exterior applications in hot climates as it is a soft and porous stone that is prone to weathering and can easily crack or become discolored due to exposure to extreme temperatures, sunlight, and moisture. It is best suited for indoor applications such as decorative sculptures, columns, and tiles. For exterior use in hot climates, it is recommended to use materials that are more durable and resistant to weathering such as granite, limestone, or sandstone.
