More glass found in a box

I made this years ago. The yellow and blue streaky glass was hand made by a glass factory in Sunderland called Hartley Woods. I visited the factory in 1992 and bought some glass. The factory closed soon after.
The panel is only about 8 inches long and 6 inches wide. I had it hanging up in the window for years.
The picture shows how the glass appears just on a white background and when there is light coming through it. The orangey red is the most different.
