In a large bowl, stir together warm water, yeast, and sugar. Let stand until creamy, about 10 minutes.
To the yeast mixture, add the oil, salt, and 2 cups flour. Stir in the remaining flour, 1/2 cup at a time, until the dough has pulled away from the sides of the bowl.
Turn out onto a lightly floured surface, and knead until smooth and elastic, 3-5 minutes. Lightly oil a large bowl, place the dough in the bowl, and turn to coat.
Cover with a damp cloth, and let rise in a warm place until doubled in volume, about 1 hour.
Deflate the dough, and turn it out onto a lightly floured surface. Divide the dough into 2 pieces.
Shape each piece into a loaf. Place on greased baking sheet or French bread pan. Score 4 times across the top with a sharp knife.
Cover the loaves with a towel, and let rise in a warm place until doubled in volume, about 40 minutes.
Place a shallow pan with 1" of water on bottom rack of oven (I use an 8x8 brownie pan). This will create steam while the loaves bake. Preheat oven to 400 degrees F.
Beat water and egg white in a small bowl with a fork until mixes. Brush over loaves.
Bake loaves for 25 minutes or until golden on top.
Brush with melted butter.
