In one of your other posts you asked why do some people use six or more coats of oil on their carving; well, you've just discovered part of the reason with your recent experience. When you coat an article with oil, it has to be an oil that drys and hardens; that's why it's a very bad idea to use olive oil, vegetable oil etc., they don't dry, they just go rancid and provide no protective coating at all. But just because you've used a drying oil, it doesn't mean you can apply a few coats and then you're done for the long term. If you want to do this properly, the old tried and tested way to protect wood with oil is: Once a day for a week, once a week for a month, once a month for a year, and once a year thereafter. Cabinetmakers and carriage and coachbuilders have been doing this for many many years, and that's because that's the way it works properly. If you carve a spoon or a kuksa for display you can give it a couple of coats of walnut oil, put it on display and bob's yer uncle; If however, like your spoon, you have something kolrosed and it's to be used and washed on a regular basis, the process requires more effort and time to make your work durable. Search the net and do some research into oil finishes on wood, and learn all the rules from the ground up and apply what you learn to your projects
You'll read lots of stuff about how everybody does it their own way, but generally they are people who know and have worked to the old rules and then adapted to their own requirements.
You can't successfully break the rules 'till you've learned and practised them, and none of this is instant; it takes time to learn skills and techniques, otherwise we'd all be top-class craftsmen, artisans and artists..........
