I have been waiting for someone to say, "Yeah , I know this one, it's ... ...".
But clearly not the case. Searching for "A. Laing" does not come up with much other than "Laing Art Glass" and there seems to be no detail beyond that.
I guess the pattern ("leafs and indentations") is actually a sunflower. And the fiery part may be a reference to sun rays. Are they painted on or worked into the glass in some way?
A signature around the lower parts just above the edge can be an indicator of American work.
