Not to be picky but, that would be cast iron, not wrought iron.
Anyway, KC is correct about the Mexican origin, if it was produced within the past 30+ years. Mexico now produces most all the "intricate molded" cast iron pieces, such as the above pictured one, that can be found here n' there, including trivets, etc., etc.
Now I was told this by an expert expert, a foundry owner in Westmorland, NY, back in the early 70's, who was still in business making "prototype castings" for industry. He explained to me that for the melted iron to "fllow" to all parts of an "intricate mold" it must contain a sufficient amount of potassium, I believe it was, or the iron would cool (set) before it could flow to all parts of the mold.
He then said, US produced cast iron no longer contains that potassium like it did back when thousands of products were being made of cast iron (stoves, farm implements, kitchen gadgets, tools, etc., etc.) of which most all of them had a molded "intricate design". For instance, an apple peeler or the legs for a treddle sewing machine.
Now I found this out when I went to him to make some reproductions of a very intricate design cast iron "Lazy Susan" that I had acquired, which was about 15" in diameter and 1 1/2" high, which I figured would be "a great seller" because ..... the "wood burning cast iron cooking stove craze" was in full swing. Anyway, his first words were, ... "I can't do it, and besides you couldn't afford it, so take it down to Mexico, they can". Then he told me "the rest of the story".
