This is a selection of 3 vintage Cast Iron Trivets. Two are shaped for cooling a sad or hot clothes pressing iron. One in very good condition is marked on the bottom EMIG T51. It measures approx. 9 ¼ by 4 ½ inches with hearts and a Tulip wind mill design. I found Emig and Iron Art were two major distributors which contracted with independent foundries for their castings. Another also with 3 legs has no maker marks. It has much rust. It measures approx. 9 by 3 7/8 inches with ¾ of a inch long legs. The last in the shape of a Tea Kettle with 4 legs is also without maker's marks. It measures approx. 5 by 4 ½ inches with rust and wear. They are used with rust and wear in good condition.
