![]() ![]() Silicified remains of algae and silica pseudomorph after halite in flint. Although it has been superseded in these uses by different processes (the percussion cap), or materials ( ferrocerium), "flint" has lent its name as generic term for a fire starter. When struck against steel, flint will produce enough sparks to ignite a fire with the correct tinder, or gunpowder used in weapons, namely the flintlock firing mechanism. ![]() ![]() This "Ohio Flint" was traded across the eastern United States and has been found as far west as the Rocky Mountains and south around the Gulf of Mexico. Flint Ridge in Ohio was an important source of flint and Native Americans extracted the flint from hundreds of quarries along the ridge. Flint is one of the primary materials used to define the Stone Age.ĭuring the Stone Age, access to flint was so important for survival that people would travel or trade to obtain flint. The use of flint to make stone tools dates back hundreds of thousands of years, and flint's extreme durability has made it possible to accurately date its use over this time. The nodules can often be found along streams and beaches.įlint breaks and chips into sharp-edged pieces, making it useful for knife blades and other cutting tools. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. ![]() It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones. Flint was widely used historically to make stone tools and start fires. Copy the same video layer between two screens and it will continue uninterupted.A piece of flint, 9-10 cm long, weighing 171 gramsįlint is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Video layers can be shared between screens without connecting them in the transition designer. If you connect two scroll groups, their scroll position will be synchronized through the transition. Right click and drag on a layer, then target the layer you wish to connect it to.Select both layers in the layer list of the Transition Designer and choose Connect Layers from the Transition menu.Select both layers in the layer list of the Transition Designer and press the c shortcut key.Select both layers in the layer list of the Transition Designer and click the Connect Layers button.You can indicate that two layers from different screens are connected in a transition and they will be automatically be animated. And fortunately, we have an easy to way to connect layers and achieve this behavior. This can be surprising at first, but it allows more flexibility, and allows a big reduction in the complexity of your prototypes. That means if you have a small photo on one screen, and a large version of it on another screen, the small layer won't automatically scale up to the large version. Flinto doesn’t keep track of layers between screens automatically. ![]()
