We are planning on selling the ammonium chloroplatinate in the Fall. We are
currently selling our Ziatype materials, which are based on lithium
palladium chloride and which we believe is an improvement on the
Pizzaghelli/Ware method. Since the lithium palladium chloride is extremely
hygroscopic, we have found that it will support up to 25% potassium
chloroplatine addition. Initial tests have shown that there is little reason
to go beyond the 25% platinum factor unless one is to have the prints assayed.
