Learning how to draw like an artist is a lot easier than you might think. Any drawing can be broken down into smaller pieces. If you follow the smaller pieces (or steps) one by one, you'll be amazed at how quickly you'll learn how to draw everything from animals and plants to buildings, cars, trains, and even dinosaurs!

To begin learning how to draw, you'll need a few basic drawing supplies including a pencil, pencil sharpener, an eraser, a felt-tip pen, and paper. In each article, the first drawing will be a completed example of the subject that you are about to draw. Examine the lines and shapes of the subject carefully before proceeding to the first step.

Do not touch the TLC plate on the side with the white surface. In order to obtain an imaginary start line, make two notches on each side of the TLC plate. You can also draw a thin line with pencil. The start line should be 0.5-1 cm from the bottom of the plate. Tri-Cities Laboratory 7131 West Grandridge Blvd. Kennewick, WA 99336. Contact TCL 509-736-0100 1-800-213-6372.

The instructions in each article will always start with larger basic shapes, such as ovals, rectangles, and triangles, depending on the subject. Draw the full shape, even if some of it will not be seen in the final drawing. The red lines in each illustration show exactly what to draw in that step, while the lines drawn in previous steps are shown in gray.

After all the steps are complete, use a felt-tip pen to go over the pencil lines. Ink only the lines you want to keep in the drawing. Let the ink dry, and then erase the extra pencil lines.

Once you've inked in your drawing, the next step is adding color. We'll learn about coloring drawings in the next section.

The last step in learning how to draw is adding color.

Use the first illustration in each article as your guide. Feel free to use crayons, colored pencils or markers. If you're feeling especially creative, you can even try watercolors or chalk.

Start by adding the main color, gently adding darker colors to areas that would be in shadows or less light (generally toward the bottom or underneath the shapes). This is called shading.

After shading is complete, add lighter colors where more light would be (usually on the top areas of the shapes, where sunlight would naturally hit them). This is called highlighting. Shading and highlighting help the drawing look more realistic.

Once you fill in all the colors and are pleased with your drawing, you're finished. Way to go!­

The spots are streaky or 'blobby'

The components of a sample can appear as long streaks or 'blobby' spots on a TLC plate if the samples are run at too high a concentration.

Tlc Drawing

For example, Figure 2.27b shows an eluted TLC plate containing five red food dye samples of different concentrations (lane 0 contains the dye in the concentration found at the grocery store; lane 3 contains 1 drop of dye diluted with 3 drops of water, etc.). After elution, the red and pink components from the undiluted dye (lane 0) streaked severely, as the TLC plate was 'overloaded'. When this happens proper equilibration between stationary and mobile phases does not occur. With further dilution (lane 12), the streaking disappeared and the spot shapes sharpened.

If streaking is seen on a TLC plate, the sample should be diluted and run again.

Figure 2.27c also demonstrates how dilution can improve the shape of a spot after elution. In this TLC, alkene and alkyne samples were spotted at somewhat high concentrations, while an improved dilution was used in Figure 2.27d. Note how the (R_f) appears to change in the two TLC plates. The more accurate (R_f) is of the diluted sample. Running TLC on concentrated samples gives inaccurate (R_f) values and may hide multiple spots.
