Pattern 918 Spode bone china Bute shape Coffee Can, this is a re-do of Spode's pattern number 878 decorated with an additional band of platinum lustre. This pattern was introduced at Spode c1806.
Henry Daniel was in the business of decorating Spode's bone china production from c1805 & John Hancock who worked for Henry Daniel had been the inventor of this new form of lustre decoration. For whatever reason, this platinum lustre decoration was only used on Spode's patterns for two years, 1805 & 1806.
Although Josiah Spode II & Henry Daniel went on to produce gold lustre decoration which appears between Spode pattern numbers 1091 & 1397, (equating to c1807-1809), see pattern 1194 (illustrated) for an example of this type of lustre.
Following this Wedgwood introduced his 'Moonlight' Lustre decoration c1810 which is a type of gold lustre.
English Silver lustreware became very popular during the 1810-1840 period of the 19th century. It also spawned mass quantities of Copper lustre wares. Lustreware was particularly popular & used by manufacturers of cheaper pottery wares rather than porcelain goods.
Perhaps it was liked because it had the appearance of something more expensive than it's actual cost. You can see a complete Service with this decoration (not Spode) here:
I believe there are around 33 Spode patterns which incorporate some platinum lustre in their designs. The pattern numbers range from 800 to 949 which equates to the years 1805 & 1806.
The usual couple of spots inside but this Spode Coffee Can is in extremely good condition for its age.
The base of this Spode Coffee Can is not marked with a pattern number which is as expected for this period.
