Take our 100 x 100 pixel image again. Suppose it's set at 100 PPI (producing the same 1 x 1 printed image). With re-sampling off, when you adjust the PPI the dimensions adjust as well, this is how things worked in the example above. With re-sampling on, the dimensions won't change.
Leftover charcoal ash can be used to help increase the pH levels in your yard. Rather than use lime and potash as a fertilizing material, collect ash in a metal bucket over the course of a grilling season and then spread the ash on your yard in an amount of no more than 10 to 15 pounds per 1,000 square feet.
Add 1 to 2 cups of soaked, drained wood chips, or 2 to 4 chunks, to the coals when you start to barbecue, and again whenever you replenish the coals (about once an hour see the next section). Refueling a Charcoal Grill. As charcoal burns, it gradually generates less and less heat.
