Carl Harrop, a professor in the Ceramic Engineering Department at The Ohio State University, founded Carl B. Harrop Engineers in Columbus, Ohio in 1919. The previous year he had been granted a patent on a new type of car tunnel kiln, a device for firing ceramics in a continuous process which saved substantial energy over the traditional batch firing methods. Harrop’s first project was to design two of these tunnel kilns to fire vitrified hotel ware for the Chelsea China Company in New Cumberland, West Virginia. In 1923, Harrop designed and built the first tunnel kiln for clay brick in the U.S. for Ohio Clay Company in Cleveland. Another notable first was the technology application of electric energy for firing glazed ceramic tile, with the construction in 1929 of Harrop’s first electric tunnel kiln at American Encaustic Tiling Co. in Zanesville, Ohio. Harrop was also pioneering the design of other types of continuous kilns, with its construction of the first pusher plate kiln for firing pottery ware at Crooksville China co. in 1930. In 1927 the company incorporated as Harrop Ceramic Service Company, with Carl Harrop as president until his death in 1934. Leadership passed in 1936 to George D. Brush, a civil engineer who had worked for Harrop since 1923. Read More







Robotic Sagger Handling System

Harrop has successfully commissioned a custom engineered robotic sagger handling system and sagger filling system for automatically filling saggers with ceramic material and placing the saggers on the kiln car. After the material is fired, the robot removes the saggers from the kiln car, empties the fired material into a container and the sagger filling process is repeated, followed by placement of the saggers back onto the kiln car.
