Glass: A Pocket Dictionary Of Terms Commonly Used - Corning ...

Ancient glass: A term frequently used to mean all preroman
and ancient roman glass.
Annagelb, Annagrün (German): Two types of glass colored
by adding uranium oxide to the batch. Annagelb
is yellow, and Annagrün is green. They were developed
by Josef riedel (1816–1894), who named them for his
wife, Anna, and they were made from 1834. See also
Uranium glass.
Annealing: The process of slowly cooling a completed
object in an auxiliary part of the glass furnace, or in a
separate furnace. This is an integral part of glassmaking
because if a hot glass object is allowed to cool too
quickly, it will be highly strained by the time it reaches
room temperature; indeed, it may break, either as it
cools or at some later date. Highly strained glasses
break easily if subjected to mechanical or thermal
shock. See also Lehr.
Applied decoration: Heated glass
elements (such as canes and trails)
applied during manufacture to a glass
object that is still hot, and either left in
relief or marvered until they are flush
with the surface. See also Marquetry
and Pick-up decoration.
Appliqué: in glassworking, a bit of hot
glass, usually small and disk-shaped,
attached to the surface of an object for
decorative purposes. Appliqués can be
decorated by pressing them in a mold
before they are attached, or they can be
stamped after they are attached.
