"It's a slow push through the kiln," Burkhart admits. The heat starts off at around 500 degrees but about a third of the way up the tunnel it hits 1,950 degrees in what is known as the fire zone. The bricks gradually come out the other end and they're still rather warm. The final results all meet ASTM specifications. Six to eight people working eight hours a day, five days a week on the mud-throwing line account for about 150,000 bricks in a week. The company also has a "special shapes" room where workers throw mud into a variety of molds to create additional products. A 45-year-old venture, it got its start when ceramic engineer Dudley Frame bought a young brickmaking company that was failing. Having experience designing kilns, he helped develop much of the machinery for his new business. Restoration projects were the main focus originally since, thanks to the distinctive process, the bricks have an old-world look. "We make it just like they were made hundreds of years ago," says Burkhart, then thinks about it briefly and adds, "thousands – like Moses' time."

The latest experiment, sequencing genomes of plants grown and harvested in orbit, was launched on February 19 as part of the SpaceX CRS-10 mission. CREDIT: CHRIS THOMPSON/SPACEX Researchers from the University of Florida sent plants into space on February 19 in the continuing effort to understand how to grow plants in a no gravity environment. When plants are exposed to a new environment, their "gene expressions" have to adapt. The thousands of genes expressed in a particular cell determine what that cell can do. As zero gravity is outside the evolutionary plant experience, new genetic patterns will be needed. The plants sent on the SpaceX CRS- 10 mission to the International Space Station will be grown, harvested and returned to Earth. Once back on Earth, the scientists at the University of Florida Institute of Food and Agricultural Sciences will sequence their genomes to see what changes in gene expressions occurred in orbit. h a rd s c a p e n e w s continued from page 16 Besides the standard bricks made with help from this "mud throwing line," the company also hand molds clay to produce a variety of special shapes and ¾" thin brick, which is growing in popularity according to a recent survey. The products all meet ASTM specs.
