Head-grain polishing claims

Early twentieth-century trade publications promoted a finish described as granite sawn and polished on the head grain. They contrasted it with an older process they characterized as bruising the surface and claimed the newer finish held its lustre longer. Those durability statements are period trade claims, not independently verified findings. (GMB16 PDF p.20; printed p.13; MN15 PDF p.13; printed p.6)

A sales argument

The 1916 issue presents the head-grain method as a selling point and says it would produce a more durable polish. The article is promotional in tone: it connects the claimed finish to customer appeal and business advantage. Readers should attribute the claims to the publication rather than treat them as settled material science. (GMB16 PDF p.20; printed p.13)

A second period reference

A 1915 issue also describes work as sawn and polished on the head grain and argues that it compared favorably with hammered surfaces. Read together, the pages show that finish was discussed both as a visual characteristic and as a sales distinction. They do not provide a current test protocol or a basis for ranking today’s products. (MN15 PDF p.13; printed p.6)
