is only with great difficulty that it can be 
made to yield even a faint yellow stain, 
kelp glass is prepared, on one side, to take 
stain of any depth from yellow to deep red. 
Some of the earlier reds thus produced in 
the eighteenth century already show iri¬ 
descence, and in a very few cases quite re¬ 
cent red stain will do the same. But if 
stain is a clear yellow when seen through, 
and iridescent when laid flat, a hundred to 
one it is earlier than the beginning of the 
eighteenth century. 
For the collector’s convenience it will be 
as well to divide all stained-glass into two 
classes—one painted before and the other 
after the middle of the sixteenth century. 
Broadly speaking, glass from the earlier 
periods is thick, is grossed, has lines, 
reams, or striae, on its surface, bubbles in 
its interior, and generally shows corrosion- 
holes. Later glass is thin, comparatively 
smooth — very smooth indeed after the end 
of the sixteenth century — is cut with the 
diamond, shows no striae, fewer bubbles, 
and where it has decayed the corrosion 
shows only as a mere patina or roughen¬ 
ing of the surface, with none of the well 
marked cavities that break the surface of 
the older Gothic glass. 
Bearing this rough division in mind, the 
collector should be able to separate his 
purchases into the two periods, and he can 
then proceed to examine them in detail. 
If any of the earlier pieces show corro¬ 
sion-holes larger than one-eighth of an 
inch in diameter, or if the whole surface 
of the glass has decayed away, leaving it 
rough to the touch, the chances are that 
it is at least as early as the beginning of 
the fourteenth century. 
If the glass is thin and clear and has 
been cut with a diamond, it may safely be 
set down as post-Renaissance work, the 
mark of the diamond on original edges 
being a certain indication of this later date. 
For the convenience of the collector En¬ 
glish pre-Renaissance glass may be subdi¬ 
vided again into two classes, distinguished 
from each other by the quality of the out¬ 
line-color. No sharply drawn date-line 
can be drawn between them, but, broadly 
speaking, one appears before the other 
after the middle of the fourteenth century. 
The earlier outline-color is of an intensely 
strong black, while in the other case it is 
reddish brown.
