Davidson Primrose Yellow Pearline William and Mary Pattern Small Jug 3-1/2"

In 1889 Davidson's introduced one of their most popular and successful lines, a colouring which they called "Pearline". It was only made in two colours, blue and lemon yellow, each with a white edge. Pearline glass was so successful that Davidson's introduced a new suite of designs made in "pearline" almost every year until 1903, and continued production of pearline until the outbreak of the First World War (1914).

Primrose or Lemon Pearline is often called "Vaseline Glass", which is a general term used for any kind of yellow glass with an appearance similar to the old yellow vaseline ointment. Pearline glass reacted to heat by turning white on the parts exposed to heat during the cooling process, a reaction caused by the chemicals mixed into the glass (notably arsenic). It was extremely popular in the 1890's. The lemon colour was produced by adding uranium oxide to the glass mixture (in those days before people knew uranium was dangerous). If you shine an ultra-violet lamp onto Davidson's lemon pearline glass it will glow green (fluoresce) because of these ingredients. Once cased in the glass the radiation emitted from the uranium oxide is negligible and not considered harmful. At 12" distance it can't even be detected.
