In the past, many materials have been used for memorials. Historically, it has been a matter of what was available or affordable; a mound of rocks, a stick or slab of wood, concrete, metal, a tablet of stone.
In the cemeteries we are familiar with today, we have seen memorials made of wood, field stone, concrete, masonry, soft marble, limestone, hard marble, various metals -cast and fabricated, and even laminated glass. All have shown signs of weathering or deterioration. Only the granite monuments have weathered more than 100 years without decaying.To the right is a photo of a cross made of concrete.
