My daughter requested four 1-liter bowls made out of kiln-dried ash. After making each bowl I add a liter of mineral oil and mark the level, which I will turn into a, etched marker-line. Of course she knows it won't hold hot soup and should only have wet vegetables for the duration of the meal, with a re-coating of oil as needed.
The mineral oil quickly soaked through the end grain. No dripping, just a soak-through. My plan is to keep on soaking for several rounds.
1. Is this a sign that ash is too porous for this intended usage?
2. Is there ever a time to use a poly / oil / mineral spirits for a wooden bowl - not to form a water-proof surface but to cure thicker than oil inside the grain?
