![]() It seems like every book I have read says "don't use olive oil for a finish on your salad bowls because it can/will go rancid" Well I do a lot of shows and run into people who want to know how to get the sticky, stinky, gummy feeling stuff off their bowls. As near as I can tell the best answer is to burn it in the wood stove. I run into the same number of people who have had the same bowl for 20 years and all they ever put on it was olive oil, and don't get the buildup or smell. I don't understand. I was at a show in Seattle and talking to Loyd General, a bowl turner from Redding, CA. and all he puts on his bowls is olive oil. He hasn't had any rancid problems. His theory is that the grade of olive oil can make all the difference, with the lower grades being much more pungent. Also he said that mixing of different vegetable oils can cause problems. I have also had cooks tell me that walnut oil can go rancid. It is a bit confusing. For now I tell my customers to wipe it out well after use and not to let it sit until the next day. I don't need any help in being somewhat confused, but would like to hear from others. Currently I use a blend of walnut and mineral oils, and then hand apply beeswax, which is then hand rubbed in while on the lathe. I have noticed that this makes a nice hand lotion for my hands after sanding the bowls. robo hippy |

People who stack bowl inside of bowl, reducing the availability of oxygen are going to run into problems. The oil itself can also cause rancid odors if it's very thick, and the surface keeps the interior oil from oxidizing. Free circulation - no rancid. No matter what finish you put on, unless the customer wipes with detergent to emulsify and clear away the surface oil after use, it will eventually build. Walnut oil is a great choice, because it does cross-link and cure, but, without siccatives, it takes a while, and if you deny oxygen, it'll smell rancid. Look at the bottle and you will see that you want to refrigerate after opening. This is to slow the chemical process as you provide more and more oxygen. Lots of people like mineral oil, but it has its dark side as well. As it never cures, it's subject to weeping in the sun, collecting dirt, and sheltering bacterial spores and the bacteria themselves in a lipid-friendly environment. What kills bacteria is the destruction of the cell wall by detergent action. Of course, the same action emulsifies the mineral oil, so you can't be really clean unless the "finish" is gone. As to your mix, you've rediscovered cold cream, plus or minus a few odorants and alcohols. |

Maybe the finish on a salad bowl matters while selling it, but most
salads will be dressed with everything from anchovy to blue cheese plus a garlic rub and (_extra virgin) olive oil. Salad bowls that are used will end up with a 'salad dressing finish' regardless. Sprinkling salt into the soiled bowl and rubbing out with kitchen paper, the way pre-teflon chef's skillets were cleaned, is one way to clean and avoid a gummy, rancid oil finish. Hand washing with soapy water, another. Rinse well & dry right away. If only greens or fruit are put in the bowl, no finish is needed. A salad bowl ought to smell like salad anyway, otherwise let them settle for ceramic and you turn bottle stoppers ![]() point by suggesting that you leave the bowl unfinished (well maybe a little mineral oil & wax for looks) so the buyer can customise with a favorite dressing. You might want to have bottles of various dressings, salt and kitchen paper for them to finish and season their treasures on site when purchased. Maybe not, but at least, you would draw a crowd of sniffers! Sorry, I got carried away. I do love to build and consume a good salad. I'll discuss the unfortunate *******izations of a proper martini another time.

How about everclear or highest octane potable alcohol available to
clean the wood down to bare and then re-oiling? I like walnut oil personally... |

Alcohol, a polar solvent, doesn't work too well against oil, a non-polar compound. Now as a cough medicine, Everclear's pretty good with tea, honey and lemon.... |

I do have a personal sized ash bowl that I take to all of the shows I
do. It is 5 years old. I use it to show how a bowl can age, for product testing, and because when I take it to a food booth and ask for a fill up, they seem to give me larger portions. I've had ice cream, stirfry, bar-b-que, pasta, pizza, Mexican, tofu, fries, cakes, cajun, and anything else I can fit in it. It started out snow white, and now is a beautiful amber. All I have done thus far for maintenance is to wash in out with water, and dry it. No soap thus far. I haven't noticed any oil build up. The outside of the bowl is a little dry, but the inside is fine. Cheese cake leaves the most beautiful sheen on the bowl when I'm done. robo hippy Arch wrote: Maybe the finish on a salad bowl matters while selling it, but most salads will be dressed with everything from anchovy to blue cheese plus a garlic rub and (_extra virgin) olive oil.

If you are concerned with the wood absorbing the contents of a salad, the
oils or other potentially foul smelling stuff, then why not make the wood impervious to having stuff penetrate into the wood? I use Waterlox - about 4 coats and the bowl is protected, beautiful and easily washed clean! Just flood on 1 coat, wipe off excess - let stand for about 15 minutes, then wipe another liberal coat intot he wood. Come back the next day, lightly sand at 400 grit by hand and apply another coat let stand for about 2 days. Then hit it again with steel wool then another coat using a paper towel to push the Waterlox into the pores and cover the surface with a thin layer and Tada!

I have never used Waterlox, or any other type of surface finish like
spray lacquers. It seems like most of them will crack, chip and peel off eventually. Then to repair, you have to strip and refinish. I do use Deftoil, with urethane resins for some of my 'art' pieces which is the same finish I use on my furniture pieces. Easier to repair. I have heard that it is ok for utility pieces, but the public seems to prefer the walnut and mineral oil finishes. robo hippy Ray Sandusky wrote: If you are concerned with the wood absorbing the contents of a salad, the oils or other potentially foul smelling stuff, then why not make the wood impervious to having stuff penetrate into the wood?

Waterlox is not a surface finish. It's a penetrating oil finish. It
won't crack, chip, or peel. me robo hippy wrote: I have never used Waterlox, or any other type of surface finish like spray lacquers.

I use thinned Minwax polyurethane, two coats, which gives pretty good rejection, and dull any areas of the surface where I might have dense enough grain to get some surface sheen. Would not recommend it for popcorn bowls, though, as you can still get some blistering effect from the Old Maids. If you're in California, where more substances are know to cause cancer, you might get queasy about the aromatic hydrocarbons, and if a heavy metal phobic, there's cobalt siccatives.... |

Waterlox sounds interesting, I'll have to try it.
