Mexican White Alabaster is a soft and porous stone that is not typically recommended for exterior applications in cold climates. Alabaster is sensitive to weathering and can deteriorate over time when exposed to freezing temperatures, moisture, and environmental pollutants. It is better suited for interior uses such as sculptures, carvings, and decorative features. If you are looking for a stone that can withstand cold climates, it is advisable to consider more durable options like granite or slate.
