French Jet
French jet is also called
Vauxhall glass. It was
cheaper than jet and could
be mass produced. French
jet is much heavier than
natural jet or any of the
other simulants, and is
cold to the touch, while
natural jet is warm to the
touch. It has a vitreous
luster and may contain air
bubbles (Pedersen, 2003).
