Charcoal Leuders, Very introverted
Why is it called CHARCOAL leuders?
The reason it has "charcoal" in its name is because of the grey colors that the limestone shows when quarried. The grey coloring comes from the petroleum oils that is also found underground, which the limestone absorbs. Looks beautiful but we have found it creates a new set of problems.
What happens when exposed?
Stone already doesn't like being exposed to the elements, as we mentioned before, water, wind and organic growth tend to wear the stone away but we found that charcoal leuders especially hates being outside its natural underground home. Because of the oils in the stone, the process in which the stone starts to break down due to environmental circumstances seems to happen much quicker and what we've gathered from testing is that the water and sun evaporate and wash out the oils in the stone. The stone starts to lose its darker properties as the oil leaves the stone and then another issue occurs, the oil was helping keep the stones integrity.
How can we help?
The same way we help any other stone, keep as much water out as we can. Due to the nature of charcoal leuders, some extra steps can and should be taken to help keep the stone's integrity. We've ran different tests with different products and have gathered data that shows which method is most efficient at keeping water out and also help keep the stone solid.
