Meal powder is the fine dust left over when black powder is corned and screened to separate it into different grain sizes. It is used extensively in various pyrotechnic procedures, usually to prime other compositions. It can also be used in many fireworks to add power and subsequintially increasing the height of the firework.
'Mill meal' powder is a mixture of KNO3, charcoal and sulfur in the correct proportions (75:15:10) which has been ball-milled to mix it intimately. It is used in the same way as commercial meal powder or can be pressed and corned to produce true black powder.
