A flowchart is a visual representation of the sequence of steps and decisions needed to perform a process. Each step in the sequence is noted within a diagram shape. Steps are linked by connecting lines and directional arrows. This allows anyone to view the flowchart and logically follow the process from beginning to end.

The charge is heated slowly until boiling point of mercury is reached. At this point the mercury is eliminated and condensed in cooling tubes passed through water. Obviously, some losses can be produced and this can be estimated as 0.065 grams per 255 grams of mercury. The process takes two to three hours.
