So I’m building a surprise centerpiece large cheese board thing for my sister out of a slab of some hard wood. It’s 41”x 2” x 11”. I applied two coats of danish oil light walnut I think then several coats of brushed Zinsser shellac cut with denatured alcohol. First coast was de waxed seal coat. Brushing was far easier than padding for me. Put on the 4th brushed coat last night and was planning to let it set for 2 days before I do a paste wax buff out.

Sister texts me last night she wants a 4ft x 18” board that she can pour warm polenta on and serve from there. I initially get pisssd cuz the one I made her is not 18”, which I Think is too wide anyway. Then i start wondering if my finish of shellac will be able to take warm polenta.

Any thoughts?

I can do a beeswax, walnut oil mix and buff. I feel a wax of some sort needs to go on top. Granted, it will likely melt once warm polenta is put on right?

Pic of board I made so far.

Any finish is food safe once it’s completely cured. However, I’d try to talk her out of pouring polenta directly on a board that large? Where is she going to wash it?

As my sister I can say that she’s probably hasn’t thought of the cleaning up part. Maybe putting a sheet of parchment paper down would help. I guess a mineral oil and beeswax finish would be the only one that wouldn’t be effected by warm food. Unfortunately I’m 5 coats in with shellac at this point and not sanding it off.

I think shellac will be fine at those temperatures. It won’t stand up to high heat, but warm food isn’t going to be much higher than 180º or so.
