Technical description

In this sub-type both glasses are square, 3¼ inches (83mm) in each dimension. The thickness can vary between about 3mm and 1.5mm – in general thinner slides are probably later than thicker ones, as glass manufacture developed over the decades.


This was the standard British size for glass slides in the second half of the 19th century and first half of the 20th, also adopted in several other European countries.
