A 19th century dark cobalt blue Bristol glass apothecary jar. The label is made from real gold leaf with a crimson border under a curved glass front.

‘Syr Simplex’  was a sweet syrup used in the 1850s as a base for mixing with other active compounds, and also to treat infantile colic. The stopper, the jar and label are all in simply perfect condition and the deep blue colour contrasts with the brilliant gold to produce a striking effect.
