Rubber paver tiles are are easy to clean and maintain. Maintenance of these outdoor deck and patio tiles typically includes: 1  Sweeping the surface of the tile with a stiff outdoor bristle broom when necessary.2  Spraying or hosing off the tiles with clean water as needed.3  Vacuuming the surface of the recycled rubber tiles with a shop vac if needed. 1/2 thick paver tiles are typically installed by adhering the tiles to a substrate such as an outdoor concrete pad, wood asphalt, or compacted gravel. 2  A polyurethane adhesive is normally recommended since they often can handle freezing and thawing and are moisture cured.
Damascus blades were manufactured in the Near East from ingots of wootz steel that were imported from India, as well as Sri Lanka. Archaeological evidence suggests that the crucible steel process started in the present-day Tamil Nadu before the start of Common Era.
The secret is in the steel structure. Wootz Steel consist of relatively soft and very tough matrix saturated with fine grains of very hard and abrasive particles called cementite (in some cases carbides). The matrix make the blade very tough. It is hard to break a wootz blade.uite often wootz is called Wootz Damascus. This is not an accurate definition. It is based on the visible pattern on the polished and etched steel that may resemble some Damascus patterns. The main differences in genuine Wootz Steel and Damascus Steel are the technology and the steel composition.
