Position a pizza stone near the center of the oven and a metal broiler pan on a lower rack. Preheat the oven to 450°F.
Sprinkle the surface of the No-Knead Artisan Master Dough with flour and quickly shape it into a ball by stretching the surface of the dough around to the bottom on all four sides, rotating the ball a quarter-turn as you go. Shaping should take no more than 20 to 40 seconds.
Elongate the ball into a rope by rolling it on the work surface with your hands and gently stretching until it is about 16 inches long. You can taper the ends by rolling them against the counter with your hands. Use enough flour while working to prevent sticking. Transfer to a sheet of parchment paper.
Cover loosely with plastic and allow it to rest for 40 minutes.
Dust the loaf with flour. Snip it into an Epi (wheat stalk) with kitchen shears: Starting at one end of the loaf and cutting into the dough at a very shallow angle, snip through the dough, leaving about 1/4 inch intact at the bottom; be careful not to snip all the way through the dough so it stays connected.
Lay the snipped piece of dough slightly off to the side (still keeping it intact). Cut another piece in this same fashion 2 to 3 inches from the first, laying the second piece off to the opposite side in a zig-zag fashion. Repeat this down the length of the dough.
Slide the loaf directly onto the hot stone. Pour 1 cup of hot water into the broiler pan. Bake for about 25 minutes, or until richly browned and firm. Allow to cool on a wire rack before eating.
In a 5-quart container, mix together the warm water, yeast, and salt. Add the flour, then use a spoon, Danish dough whisk, or stand mixer fitted with paddle attachment to mix until uniform. Cover (not airtight) and allow to rise at room temperature for about 2 hours.
