2. Drawing Reflective Objects
Objectives:
To learn how to draw bottles accurately;
To learn to use chalk pastels, white charcoal pencils, and erasers on black paper to give the illusion of 3-D glass.
To understand the concept of drawing glass through glass;
To demonstrate how to draw colored water to look as if it’s inside the glass container;
To use refraction to portray a paintbrush inside a glass filled with water.

3. Drawing a poor bottle versus a good bottle
What’s wrong with this bottle?
Graphic organizer:
Drawing a poor bottle versus a good bottle
Bad Bottle
Good Bottle

4. What’s wrong with this bottle?
Let’s talk about it…
Top: Ellipse is too round…should be more oval if viewed from lower perspective.
Neck: Lines are straight but should be curvy.
“Shoulders” Why are they shrugging?
They should be sloped.
Bottom: drawn flat…Should be rounded.

5. Time to make a correctly drawn bottle!
STEPS:
Don’t forget to measure width vs height!
Draw a proper ellipse for top and bottom of bottle
Draw a guideline for symmetry if needed
Make sure shoulders slope correctly and symmetrical.
Bottom should be rounded. Drawing an ellipse helps to do this easily.
See example next slide...

7. ? Measure First! 1 Don’t forget to
STEPS:
Don’t forget to measure width vs height!
Draw a guideline lightly for symmetry (if needed)
Draw a proper ellipse for top and bottom of bottle- making sure they line up
Make sure shoulders slope correctly and symmetrical.
Bottom should be rounded. Drawing an ellipse helps to do this easily. 1

Glass Bottles
Reflective Qualities of Transparent Surfaces

9. Reflective Qualities:
Glass is clear but is reflective of what is around it. Look for:
Soft High-Lights:
Softer edges
Duller in value
Larger, Less defined areas
Hard High-Lights:
Harder edges
Brighter in value
smaller, more defined areas

10. Assignment: Draw a bottle first in line with pencil on black paper…
Don’t forget to measure!
Use the white chalk or charcoal and draw soft high lights…
Paying attention to defining the edges.
Use the charcoal pencil to shade more precise hard high lights
Use your eraser to carve out darker values and clean edges.

11. Refractive Qualities in Glass

12. You will be drawing 3 bottles together, showing overlap
You will be drawing 3 bottles together, showing overlap. How do you do this?
Show only an indication of the bottle in the back. If you show too much, the viewer is confused.
On the front bottle, make a clear edge with chalk pastel or an eraser to show it is in front.
Ask yourself “Which bottle is whiter /cloudier? Add more chalk to that one and make the opposite darker, ie: erase.

13. The key to drawing or painting glass is not to render the actual glass object but to render the way the glass distorts and reflects the objects around it.

14. This is an example of REFRACTION.

15. More refraction/distortion

16. The other thing to remember is that glass is reflective
The other thing to remember is that glass is reflective. This means that shapes and objects in front of the glass may be seen in it, but it also means that there will be bright highlights. These highlights are what communicate the shiny, reflective nature of the glass

17. Artist:
Janet Fish

18. What did Janet Fish do to be able to show one glass is in front of the other?
Sometimes as artists, we need to add weighted line to make an object stand out. Other times we need to make one object darker and the other lighter to be able to make the still life clearer and more appealing.

20. What to remember when drawing transparent objects:
Draw shape accurately.
Make the soft highlights.
Find shadows
They look grayish, greenish, or blueish.
Can also look very CLEAR (Not cloudy)
Find reflections (bright highlights).
Look for refraction/distortion.

21. Now onto drawing glasses with colored water!
Discuss with tablemates:
How many ellipses do you see?
Where are they?
3. What is the difference between them?

22. Discuss with tablemates….
Compare #1 to the
model. Name one big difference.
Compare #2 to the model. Name at least 2 differences.
Compare #3 to the model and name the main difference.
