I have a customer considering a zinc countertop for the kitchen. I have seen a couple of articles in magazines about zinc counters, but none address the issue of appropriate use. I know that zinc is low on the metals food chain and is affected by acids, but what about some of the possible health risks of food contact with zinc? There are a couple of small children in the house too. Zinc also appears to be fairly expensive — higher than copper in our area. Any comments or first hand experience would be welcome.

Tim,
I have never worked with zinc b4 but became interested after a post here before the change. Someone posted a link to a supplier. Don't remeber who it was but they sent me some samples. I took these and tested them with OJ, wine, cleaners, scratches etc. Zinc seems to discolor easily. It oxidizes like other metals and acids will remove oxidation leaving a spot.
Get a sample for your client and let them see for themselves if it will suit their tastes.

Thanks, I have a local sheet metal supplier who can get zinc sheets and has worked with it before. However, he all but questioned my sanity about the suitability of a zinc kitchen counter -- but couldn't deal in specifics. Also said it was more expensive than copper. Zinc counters are used in Europe (a bastion of regulation!) and a company called Soupcan, Inc. in Chicago promotes them. My client likes the idea of a "patina" developing. My plan, if zinc is used, is to vacuum press the sheets to a plywood substrate. Any thoughts. . .
Hey Tim; This opinion is based on nothing but gut feeling so you are probably getting about what you paid for, but here goes anyway. If a little strip of zinc will stop moss and mildew on a roof top, what in the world would a countertop of it do to all the food that invariably will contact it, and the dishwater soap in the sink? Somehow it don't sound like a good Idea to me. Would copper develop the appropriate patina? There are lots of cooks that use copper, I don't know that I have ever seen zinc pots. Well, thats more than I know for now.
Dan Been there, never heard of that!
Tim,
I seem to remember from a previous post that zinc is supposed to be a suitable material for counter tops. I do know that it is frequently used for bar tops.
I would pose the question of food contamination to the supplier just to be sure.
As for techniques in building a top, I would treat it just like laminate. It can be cut with a saw and filed like laminate. I am guessing that most contact adhesives will work just fine. Is this a squre edge top or bullnose? If square edge, I don't see the need for the vacuum press.

They used to make the kithen sinks from zink . A lot of old wimmen , when I was growing up , would call the sink a zink.
