From Wikipedia, so details may be missing, but it seems both smoke and illuminating rounds are a good deal older than you (or I, for that matter – I thought star shell was used in the ACW) thought.
A variety of fillings have been used in shells throughout history. An incendiary shell was invented by Valturio in 1460. The carcass shell was first used by the French under Louis XIV in 1672.[31] Initially in the shape of an oblong in an iron frame (with poor ballistic properties) it evolved into a spherical shell. Their use continued well into the 19th century.
A modern version of the incendiary shell was developed in 1857 by the British and was known as Martin's shell. It was filled with molten iron and was used against enemy warships. It replaced the use of red hot shot (notably used at the Great Siege of Gibraltar in 1782). Two patterns of incendiary shell were used by the British in World War 1, one designed for use against Zeppelins.[32]
Similar to incendiary shells were star shells, designed for illumination rather than arson. Sometimes called lightballs they were in use from the 17th Century onwards. The British adopted parachute lightballs in 1866 for 10, 8 and 51⁄2 inch calibres. The 10-inch wasn't officially declared obsolete until 1920.[33]
Smoke balls also date back to the 17th Century, British ones contained a mix of saltpetre, coal, pitch, tar, resin, sawdust, crude antimony and sulphur. They produced a 'noisome smoke in abundance that is impossible to bear'. In the 19th century British service they were made of concentric paper with thickness about 1/15th of total diameter and filled with powder, saltpetre, pitch, coal and tallow. They were used to 'suffocate or expel the enemy in casemates, mines or between decks; for concealing operations; and as signals.[33]
