that is comparable to Bullseye Lacy White or Transparent white? They are not totally opal, held to the light after fusing they let a little light through. However the dimensions (and cost) of Uroboros glass is a little more conducive to my current project.

In which type of glass?

Uroboros' website shows the available colors, and if you're not sure you can head over to Facebook and ask on their page. They'll probably give you the best answer.

You can also get a very controlled translucent effect by sifting a thin layer of white on clear and fusing it flat. If you mix white (or any pale neutral, actually) with clear powder you can open it up even more.

Thanks, I thought about using frit but I like the even consistency of the sheet. Basically this is the back for a piece that is framed for the wall. It needs to let a glow come through if hung in a window but block wall color if hung on a colored wall.

I am using COE 90 - typically double roll

Good suggestion - I messaged them via their FB page. They agree that they do not have a comparable white. The good news is that my supplier had just enough sheets of Bullseye for me to do what I need.
