The following recipes are said to be learned/discovered while randomly crafting other Engineering items in the latest build 2.4.7-6-gdc882cc.

This is not true, They are learnt by making Pandaira Fireworks http://www.wowhead.com/item=89991 and are contained within

Schematic: Autumn Flower Firework http://www.wowhead.com/item=89996
Schematic: Celestial Firework http://www.wowhead.com/item=89994
Schematic: Jade Blossom Firework http://www.wowhead.com/item=89997
Schematic: Grand Celebration Firework http://www.wowhead.com/item=89993
Schematic: Serpent's Heart Firework http://www.wowhead.com/item=89992
