Determining the coated side
of dichroic or iridescent glass
Many fusing operations require that the fuser determine which
side of dichroic or iridescent glass is coated. This is easy
for opaque glasses, but can be difficult for transparent (especially
clear) glasses.
The most straightforward way to determine which side has the
coating requires the use of a pencil or similar object. Just
hold the pencil at a slight angle so that the tip is lightly
touching the surface of the glass. Observe carefully to see if
the reflection of the pencil tip in the glass is directly touching
or if there's a space between the actual tip and its reflection.
If there's a space, the coating (dichroic or irid) is on the
opposite side; no space means the coating is on the top surface next
to the pencil.
