The Lighthouse Nightlight is made with various shapes and textures. I used multiple layers of clear glass as the background sky to allow a lot of light to shine through the nightlight.
I used reactive glass for the actual lighthouse. This means that the white part of the glass reacts when copper glass is put against it and fused. By "reacting" it forms a darker boundary around the perimeter of the border of where it intersects with the white reactive glass. It's a very subtle look.
And the finished product... it's hard to see the reactive glass as it is backlit, but I love the texture of the clear glass and the blue sea.
