That''s what I''m trying to build. I don''t know where the critical speed is that inspires such madness and communion, and life, really, but I know the table just might find it. And when that critical level of intensity is reached, there will be conversations, sculptures, readings, and parties like never before. Less than a month on the road, on a hot day in late February, the grungy banditos nervously approached the inspection station at the Arizona border. They were driving a table. They were about to get busted.Having spent auto the last week crossing the Mojave, Scott, my friend and copilot for the first thousand miles, and I were grungier than usual, and the table looked down right impossible to have a respectable conversation around. The left rear tire had lost half its air and the land-boat listed dangerously. The windshield had long since fallen out, somewhere, I think, between Barstow and Bakersfield. Although we''d duct taped the windshield frame back together, we''d jammed the wiper switch on, so that the blue wipers waved incessantly in empty space. Such quantities of chili beans, bacon grease, and wine had spilled on the table that, as we slowed down to be inspected, a great swarm of ceramic flies descended upon us. I peered through the bugs splattered on my safety glasses at the fine specimen of authority blocking our way. We had been stopped several times already and I was wondering how in the world were we going to convince him that the table, despite appearances, was a socially responsible invention designed to foster a utopian sense of community.

Brick and Refractory BasicsBrick Materials--In an EAF, the term ''brick'' can apply to a silica brick, a high alumina firebrick, or a basic brick:* Silica brick is an acid resistant brick usually made from ganister, bonded with a small amount of time. Silica brick has high resistance to thermal shock.* High alumina bricks are standard firebricks made with a high percentage of alumina ranging from 50 to 90 percent. A high alumina brick has high resistance to spalling due to rapid temperature changes.
