Being an established ceramic distributor, many manufacturing companies started to contact Dorothy and Harold to ask them if they would be a supplier of their products. Subsequently, they carry three lines of kilns (Paragon, Skutt, and Cress), instead of one, and four companies brush products (Duncan, Mayco, Gordon, and Ceramichrome). At one time they ordered from approximately 12 major mold manufacturing companies throughout the nation. Many of these mold companies have gone out of business, but we still order from quite a few.

To broaden their product line they started to supply modeling clay and wheels. This type of clay is used in the school systems, camps in the area and potters. Some other products taken on at this time were china paints and decals.

History

In order to keep up with the newest techniques, Duncan established a seminar program. This is a factory represented program where certified teachers are made available to show the distributors and their dealers how Duncan's products are used. This program encouraged more people to become involved in ceramics.
