To produce Clutha glassware, a worker used a gather of pale ruby or pale yellow glass, then rolled it over a marver lightly sprinkled with bits of colored glass and mica flakes. The gather was reheated and blown and tooled into the finished product. It was originally made by James Couper & Sons, Glasgow. It is called "Clutha" from Gaelic for "cloudy." ]]></note></mads>
