Help - Old English wood oil
I have a few wooden guampas (i.e. like tea or coffee cups) that I use for drinking mate (i.e. like tea). The wood was starting to split but hadn't broke through, so I rubbed some O.E. wood oil into it in the hopes I'd still be able to use the items. The wood is better, but I can see that some parts have the oil all the way through to the inside part of the cup.
Does this mean I can no longer use them for drinking hot liquids? What do you gals think?
Is there another way to protect wooden food utensils from splitting, without spoiling them altogether? The wood is untreated, by the way...
