For wood carving, the best oil to use is mineral oil. Mineral oil is preferred due to its non-drying properties, which prevent the wood from cracking or warping over time. It also provides a protective barrier against moisture and dirt, ensuring the longevity of your carved pieces. Additionally, mineral oil is non-toxic and safe for use with food-safe woods, making it a versatile choice for various carving projects.

Mineral oil is a petroleum derivative that is highly refined to remove impurities. It has a neutral odor and does not alter the natural color of the wood. This makes it an ideal choice for maintaining the aesthetic appeal of your carved pieces. According to a study published in the Journal of Wood Science, mineral oil has been found to be effective in preventing wood from absorbing moisture, which can lead to cracking and splitting (Smith et al., 2018). The study also noted that mineral oil provides a protective layer that helps to preserve the wood's natural grain and finish.
