The shoe that fits one person pinches another; there is no recipe for living that suits all cases.
Below is a glaze recipe list for some of my favorite glazes. I fire to cone 10 in a reduction atmosphere. Also, I use Standard Ceramic #257 English Porcelain. The commercial underglaze I use for a consistent red decorating color is Amaco V-388, Radiant Red Velvet Underglaze. After the underglaze has dried to the touch, I paint/dip Pinnell Clear (recipe below) over the top to make it food safe.
