<includeonly>[[Galalith]]</includeonly><noinclude>Galalith</noinclude> is a <includeonly>material</includeonly><noinclude>[[materials|material]]</noinclude> invented in 1897<ref>by Adolph Spitteler and Wilhelm Krische, who then patented it in 1899, see the relevant [http://en.wikipedia.org/wiki/Galalite entry] on Wikipedia.</ref> created from the formaldehyde treatment of casein (the milk protein), so much so that it is often simplistically called [[casein]], although such an indication is not absolutely correct because hardened casein does not have the chemical and mechanical resistance characteristics of galalith, whose name derives from the union of the Greek words ''gala'' (milk) and ''lithos'' (stone).
