FOR THIS ASSIGNMENT, An IMPRESSION KIT IS NEEDED AND I DO NOT HAVE ONE!! PLEASE HELP!
For this exercise, you will create casts of impressions. In your lab kit you received casting material and a bio foam box.
To be successful, let your casts sit for at least 12 hours. If rushed, the casts can break. Plan your activity and schedule accordingly to ensure you have enough time to complete.
Note: The water and casting powder in your kit comes in the same package. You might have difficulty accessing the water as it is surrounded by the powder. Cut the top off the package, pour the casting material in another bag, then access the water and add in the correct ratio.
Make four casts. This likely means you will make smaller impressions than your entire shoe.
- Cast #1: Make an impression in the bio foam and then pour your cast. Do this one first as it is the most stable surface. You can practice in this and not fear messing up your cast too badly. To ensure your casting material goes far enough, feel free to only cast part of the shoe print. A tip to make “dam” in the impression is to take a piece of cardboard and insert it vertically to stop the casting material from seeping into the entire impression. If you have children, just use a smaller shoe!
- Cast #2: Make an impression in the bio foam by pushing a quarter into the bio foam. Extract the quarter carefully and then pour that cast. Notice how much detail you can get with the casting material.
- Cast #3: Take a small paper cup (like a Dixie cup) or a Styrofoam coffee cup. Put a quarter in the cup and then put about one inch thick of casting material over the quarter. Let it sit for 24 hours. Tear the cup off and pop out the quarter. You now have a paperweight. Compare the detail in the quarter from the Dixie cup to the detail in the other quarter in bio foam.
- Cast #4: Use soft soil to make a three-dimensional impression, and again, process it like the video in the Instructional Materials, but only do part of it. Or do a small shoe.
Prepare a photo packet of your process using Microsoft PowerPoint. For each impression, provide:
- a photo of the impression before casting with a scale on the same plane as the impression;
- a photo of it after pouring;
- a photo of it when you lift it before cleaning;
- a photo of the final product.
