Abstract:
A process for producing a flame reaction member for coloring a burner flame comprising the steps of:i) heating and increasing a temperature of a raw material mixture which has a glass composition containing a salt or an oxide of a flame reaction metal which produces color in a flame to form an intermediate base material in which the salt or oxide of the said flame reaction metal has been thermally decomposed and which is in a temporary sintered state or a fused glass state,ii) grinding the said intermediate base material to produce a ground material,iii) mixing the said ground material together with a liquid and, optionally, a binder, to form a viscous flame reaction material,iv) applying the said viscous flame reaction material to a substrate, andv) heating the said viscous flame reaction material to a temperature which is not lower than a vitrification melting temperature of the said viscous flame reaction material to fuision bond the flame reaction material to the said substrate to produce a flame reaction member comprising a substrate having flame reaction material bonded to the substrate.
