Hi. Currently gravestones are pretty resilient because the manufacturers of gravestones and memorials have learned from the past. The purpose of a gravestone is to provide a long-lasting memorial while marking the grave. In the past, gravestones were made out materials (like concrete and sometimes even wood) that are subject to deterioration caused by weather. Now, most gravestones are made from marble or granite. We chose these two materials for our line of gravestones because the materials are durable and fairly weather-resistant. The inscriptions made on the stone will survive the weather and last as a memorial for centuries.
White rot fungi are able to break down lignin along with cellulose and hemicellulose in wood, resulting in white-colored decay. Brown rot fungi primarily degrade cellulose and hemicellulose in wood, while leaving behind lignin, resulting in a brown-colored decay. White rot fungi are more effective at decomposing lignin compared to brown rot fungi.
Rot, e.g. Dry rot has set in to the timber framework of the roof...... or, the tree is dead and has gone has rotten.
Macroscopically the white rot will appear as white spots on the wood, indicating that it has eaten up all the lignin and left the white cellulose behind. It does eat away the cellulose and hemicellulose too, but the lignin is delicious to them. It will appear fibrous, stringy, and spongy with the white pockets present. Brown rot is the opposite and it eats the cellulose first and doesn't do much to the lignin. it is brown in colour, and the fibrous texture is lost quickly. There is a much greater diversity of white rot, but brown rot can reduce the weight of a tree much faster than white rot. Microscopically, the fungi's hyphae secretes enzymes which attack the S2 and S3 layers of the wood and move into the tracheids. It will destroy all layers from the lumen out to the middle lamella. for Brown rot, there is extensive degradation of cellulose...the S2 layers degrade fast, but the S3 layer is more resistant. The fungi (examples to come) eat all the carbs (cellulose& hemicellulose). examples of brown rot include Gelophyllum sepiarium and Oligoporus placenus. examples of white rot include Trametes versicolor and Phellinus pini
Dry rot will affect your health because your blood will not be able to flow throughout your body. If dry rot is severe, you should get the dry rotted part of the body removed to help circulation.
Yes, pine cones can rot over time, especially when exposed to moisture and environmental factors that promote decay like fungus and bacteria. The decomposition process of pine cones involves breaking down of the materials they are composed of, such as cellulose and lignin, by microorganisms.
Monumental Stonecutters make gravestones.
Gravestones - song - was created in 2010.
Yes, we can provide photos of gravestones.
Gravestones can be purchased anywhere where there is a local home improvement center. They also may be specially ordered online if you want custom colored gravestones.

Most Gravestones are made out of Granite although some are made out of Marble. x
Hi there. Some ancient gravestones have weathered so much that you can't read the inscriptions; however, it has been found that marble or granite gravestones hold up to the weather making inscriptions readable for centuries which is why we use these materials in creating bespoke memorials that last. Concrete gravestones are more susceptible to damage. Many ancient gravestones that survived are actually displayed in museums and many still stand on the gravesite.
Hi there. The history of gravestones goes back thousands of years as Ancient grave markers have found in Greece and Rome. Gravestones, like we have today, developed around 300 years ago. Previously, wooden crosses were used to mark a grave followed by stones shaped like a coffin. Some of these grave markers deteriorated completely because of weathering. Long lasting gravestones are made from marble or granite, which is what we use for our gravestones and memorials.

they are actually secondary

Hi. Gravestones are meant to last for centuries to provide a lasting memorial; however, some gravestones have deteriorated because of weathering which can actually destroy the stone or make the inscriptions unreadable. If a gravestone is made out of durable material, like marble or granite, it will be somewhat weather resistant and the inscriptions will remain readable for centuries. We have chosen these materials for our line of gravestones and memorials to ensure that they will be enduring memorials.
