Brings out a warm, rich tone in the wood.

Raw Linseed Oil (flaxseed oil)

Walnut Oil

Popular among woodturners for bowls.

Avoid if serving people with nut allergies.

Easy to apply, but requires frequent re‑application.

Often used on cutting boards and butcher blocks.
 
 - 
 - 
Beeswax or Carnauba Wax (often blended with oil)

Adds a protective topcoat and slight sheen.
 - 
Great for cups and bowls that won’t hold liquid for long periods.
 
 - 
 - 
Shellac (dewaxed, food‑grade)

Derived from natural resin, safe once cured.

Curing matters: Even natural oils must fully cure (oxidize into a solid film) before being safe for food contact. This can take days to weeks depending on the oil.
 - 
For a coffee cup, you’ll want something more water‑resistant: tung oil or shellac are better than mineral oil alone.
 - 
For a salad or snack bowl, walnut oil, mineral oil + beeswax, or tung oil are excellent choices.
 
Practical Recommendation
- 
For your wood bowl: Walnut oil or tung oil, finished with a beeswax topcoat.
 - 
For your coffee cup: Pure tung oil (fully cured) or dewaxed shellac for better liquid resistance.
