@curly6 The slightly matte or textured surface is the result of the glass touching the mold. Unfortunately, at the temperature needed to "fire polish" something, the glass is soft enough that it will not retain the slumped shape. For future projects, you can attempt to avoid this finish by reducing the time that the glass is exposed to slumping temperatures. You may wish to set an alarm on your controller for when the kiln reaches the target process temperature so you can check the slump progress and skip to the next (cooling) segment of your cycle. This may help prevent the glass from fully settling into the mold and imprinting the texture of the ceramic mold surface.

@ When determining what size border came to use on a panel, there can be a few considerations, and there's not an absolute answer. Is the panel going to be hung in a window by hangers, is it being installed into an existing opening such as a cabinet door or window frame, or are you building a custom wood frame to finish your art? Are you using a rigid (zinc, brass or copper) came or lead came border? For projects that will be well supported by a frame, you may opt to choose a narrow border so the came remains hidden in the channel of the frame or behind finish trim work. For art that will be hung, or may be less supported you may wish to use a wider border. This will not only provide a bit of extra strength, but provide a nice defined border. For a 14" x 17" panel, our instructors would recommend 3/8" adjustable U came. This will provide support, and the design of the channel will make it easier to install hanging rings securely.
