Could someone tell me if there are any opaque glazes that will work with =
one coat? For detailing, etc., it is very time consuming to have to =
apply 3 coats. Thanks for any help!

It depends on the color, your firing temp, and what clear (if any) you put
Some years ago, I made test tiles aprox. 12"x6" which have been really
helpful, first to me, then later for my students.
I attached a coil (pierced with a hole thru it), and made several areas
with different textures, ie.: deep grooves, scratched grooves, smooth
"dips" with a wood tool, that ran the length of the tile horizontally. I
put holes in them for hanging.
I applied the underglazes vertically from top to bottom, grouped according
to color on each tile. First I made three brush-wide stripes of the color,
stripe #2 & #3 got a second coat, and stripe #3 got a third coat. I did
this all the way across the tile, using different colors each time. I then
applied a stripe of clear glaze (every kind that I had in the studio, ex:
matts & clears/ different brands) horizontally across the colored stripes.
I even applied some translucent glazes this way. Then I fired them.
This gave me a clear picture of what each color would do with 1,2 & 3
coats, how they would respond with the different glazes on top, and how
they would "break" over texture.
I was still in school then, so some of my tiles got severely overfired, but
that was good because I discovered that some underglazes would go much
higher and flux on their own (without the clear on top).
I hope this helps,
