Cross Contour Geologic Tiles
Lesson Plan & Artwork by Eric Orr
We live in a world of varied and interesting land forms. These forms were created over millions of years as a result of tremendous pressure under the earth's crust. Magma from the earth's mantle pushed up, folded and sculpted the earth. Many of these geometric and linear forms are visible from the air. Mountains were formed both by volcanism and the movement of tectonic plates pushing against one another. Erosion over millions of years by weather and glaciers worked to wear down forms creating hills, planes, valleys, moraines and rivers.
- Students will create 3-D land forms on soft clay tiles. Forms can be pushed up from under the tile, or added as geometric forms to the tile surface.
- Tiles will be glazed with colorful Mayco® Stroke & Coat® Glazes and then decorated with a cross contour linear pattern using Mayco® Designer Liner.
- Cross contour is a drawing technique which produces often parallel lines similar to those found on a U.S. Geologic Survey contour hiking map, where lines trace areas of similar elevation.

Roll out a pound of clay (orange size) into a disc 1/4 to 5/16 inch thick. (White clay will show color best).
Using a tile cutter or cardboard template, cut slab into a 4, 5 or 6 inch tile. Tile does not have to be square.
Make the tile 3-D by pushing up land forms gently from the bottom side of the smoothed clay tile. Geometric Forms may also be added to the surface by scoring and slipping them before pressing to the surface. Forms may be realistic or imaginary. Hollow out any that are thicker than your index finger, and be sure to pierce an air escape hole.
The tile clay surface should be smooth to facilitate later Mayco® Designer Liner pattern. However, an interesting tile border or frame may be created with press tools.
Dry the tiles and bisque fire to cone 04, (1945 degrees F.)
Using Mayco® Stroke & Coat® Glazes, brush on 2 to 3 coats of glaze, making sure to allow glaze to dry between coats. Glaze may be used to emphasize or connect the land forms.
Choose several Mayco® Designer Liner colors and use them to create linear patterns on and around your forms. Parallel lines work best.
Wipe glaze off tile bottom and glaze fire to cone 05 or 06 (1888- 1828 degrees F.)
