Green stars composition

In practice, both red and green star compositions are formulated to have a negative oxygen balance i.e. there is an oxygen deficiency) since the presence of a reducing atmosphere in the flame inhibits the oxidation of MCI to MO (where M is Sr or Ba), thus enhancing the colour purity of the flame. 

Inside the plastic cone at the head of the rocket might be a payload of small green stars, each about the size of a pea, based on a composition containing barium nitrate (36%), potassium chlorate (48%), shellac (13%) and dextrin (3%). 

A red star might be based on potassium perchlorate, strontium carbonate and charcoal together with various binders and solvents to facilitate the pumping of solid stars. The composition for a green star... 

The second German edition of Ruggieri s book (we have not seen the first) contains a Nachtrag or supplement which lists nine compositions,10 of which four contain Kali oxym. or potassium chlorate. These are (1) for red fire, strontium nitrate 24 parts, sulfur 3, fine charcoal 1, and potassium chlorate 5 (2) for green fire, barium carbonate 20 parts, sulfur 5, and potassium chlorate 8 parts (3) for green stars, barium carbonate 20 parts, sulfur 5, and potassium chlorate 9 parts and (4) for red lances, strontium carbonate 24 parts, sulfur 4, charcoal 1, and potassium chlorate 4 parts. Ruggieri says ...

Polyacid-modified composite resins are favoured by many clinicians over conventional composites to repair primary teeth [50]. This is on account of their fluoride release [1,50]. To emphasize their application in primary teeth, certain brands have been specifically produced for this purpose and are highly coloured. For example, in America, there is a dual-cure compomer called MagicFil (Zenith Dental, Englewood, New Jersey) which is produced in four colours (pink, green, blue and yellow) with gutter inclusions, and a similar material, Twinky Star (Voco, Germany) is available in Europe [51].
