Look at the gills on the underside of the cap. They should be attached to the cap, close together and grayish in color, becoming darker and finally ending in a very dark brown, states Lycaeum.org.
Identifying chainsaw chains is important for the safe operation of a chainsaw. Placing the wrong chain on your bar can be very dangerous for your legs and the saw’s engine. Luckily, manufacturers have come up with an easy set of guidelines for you to determine the pitch, gauge and length of every chain. You should also check on the box the chain came in for these measurements to make sure they match the recommendations for your saw.
Use the wrench to remove the bar nuts on the clutch cover. Take off the bar, clutch cover and chain.
Determine the length of the chain by counting the number of drive links on it. The drive links are opposite the chain’s teeth and run over the slot on the guide bar.
Identify the chain’s gauge. This is the measurement for the thickness of the drive links, so they will need to fit specifically in your guide bar’s slot. This number can be found on the chainsaw chain or on the chain’s box. Most hand-held saws use thicknesses of .050, .058 and .063 inch.
Identify the chain’s pitch. This is the measurement between three consecutive rivets on the chain divided by two. The rivets keep the chain links together and determine the size of the chain. Most saws use a pitch of one-quarter to three-quarter-inch pitch, and this measurement can be found on the chain or on the chain's box.
Make sure the chain’s gauge, pitch and length all match the recommendations in the user manual.
Agates exist all over the world and are common in Idaho, Washington, Montana and Oregon. Agate is identical to quartz in terms of composition and physical properties. To identify rough agate, consider its translucence, size, weight and banding, and look for surface marks, irregular fractures and waxiness.
Open the Stone
Look for Translucence
Inspect for Banding
Measure the Stone
Check the Surface
Feel for Waxiness
Study for Fractures
Use the location of your stone to narrow down your agate type options. For example, a cross-section of a Lake Superior agate reveals thin concentric alternating bands inside, ranging from clear or white quartz to deep red jasper but may also include yellow, orange and violet.
Use a chisel and hammer to break open the stone. If you want smooth edges, take the stone to a jeweler who has a diamond saw, and ask him to slice it in half.
Examine the stone for translucence. Agates come in a wide range of colors, including red, blue, white, orange, pink, brown, green, yellow, gray, purple and black. Some agates are multicolored. Whatever the color, most agates are translucent to some degree. Use a flashlight to back-light the stone and spot any translucent edges.
Many stones look like agates but aren't. For example, jasper and flint are closely related to agate but are opaque, not translucent.
Look for banding or layers of different colors that are approximately parallel to the sides of the cavity. Riband agate has bands of white alternating with black, brown or red straight lines in cross section. This is onyx. Concentric circular bands of different colors indicate ring or eye agate. Most agates have some sort of banding, but there are exceptions, such as moss agate. Moss agate has no banding but is still called agate because it has more than one color.
Measure the diameter and weight of the stone. Typically, an agate is the size of a golf ball and feels heavier than it looks due to its density. Compare the stone to other stones. Use the diameter and weight of the stone together with your other observations to identify the type of agate.
Inspect the surface of the stone for pit marks. Agates sometimes form in igneous rock and are surrounded by softer rock that erodes away, which can result in surface pitting.
Slide your fingers into a crack in the stone or a part of the exterior that has worn away. If you feel waxiness, this is a sign of an agate.
Look for irregular fractures, known as conchoidal fractures, which agates are prone to. The fractures may be curved with a wavelike pattern.
