Oil paintings are not covered in glass because oil paint continues to cure and breathe over time. Encasing it under glass could hinder this natural curing process, leading to potential damage. Moreover, glass can create a barrier between the viewer and the texture of the oil paint, which is often integral to the artwork’s appeal. Instead, proper framing and distance from potentially damaging elements like direct sunlight are recommended to protect and preserve oil paintings.
