But if you want to do it now, you can use polyurethane wood varnish to replace the lacquer, in the chemical wholesale and retail market can buy the color powder material, there are transparent and opaque many kinds. But I would like to point out that the effect of doing so is certainly not the traditional craft out of the kind of flavor.
As for the cooking oil well that is certainly not, cooking oil is the pigment can be dissolved open, but cooking oil can not dry ah, even if the wood is absorbed by the color can not hang.
