Oh no, did you really say that? I have a terrible Ikea addiction and there happens to be one less that two miles from my house. Now I have an excuse to head over there.
Thanks for the chemical explanation. I did put a bit of flaxseed oil (before knowing about mineral oil), so I'll have to see if it rances and/or becomes sticky. It does sound however that if it creates a plastic like substance that would create a waterproof cover on top of the wood while the oil should still nourish a bit. I don't have experience yet in it, so I wonder what people experienced using non-mineral oils.For those interested in the science..... (sorry but it's my thing)
Veggy oil, lard and the like are triglycerides (3 fatty acids attached to glycerol backbone). With time these glycerides detach and react with other things like the wood pulp. Many natural oil glycerides also have sections that are unsaturated so they react with the air and become rancid. The rancidity helps to cross link with other glycerides to create a gummy plastic like substance. (application example:If you use flax seed oil (linseed) a very unsaturated oil, wood dust and natural fibers, roll into sheets and heat it up you end up with linoleum.)
Better to use a mineral oil (pharmacy grade or food grade).
Melted beeswax is good also.
These substance are not glycerides, are saturated and unreactive.
