Original gravy boat made from a single piece of birch burl

This is a small sauce bowl with a volume of 80 ml named "Caterpillar", its peculiarity is that it is made from one single piece of birch burl, firstly it is very hard wood, secondly it is not processed with chisels on the outside, only the bark is removed, this is a very rare case . I impregnate all products only with natural impregnations - edible linseed oil, propolis and beeswax, as my ancestors did.
