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.
Clean out your grill well before each use! A pile of charcoal ash in the bottom of your grill or on the charcoal grate will not allow adequate airflow to your charcoal, no matter what charcoal starter you use. Your coals will light easier and burn hotter with adequate air circulation. Use enough charcoal.
