Using a vacuum forming method, I created a raised trapezium shape onto the surface of a sheet plastic. Then, I tried flatten down the raised area by reheating and vacuumed in to a flat board. I found that there is a limit on the no. of time it can be reheated. After 3 times, the surface broke. 

What i like about this result is the pattern that was made by the template board and was distort when i flatten the sheet.

I went into the school shop today just to see what new materials i can experiment on. I found this material, alginate. The funny thing is that it was labelled "dentist use only". 

I just discovered that it can cast to such good details.

Casting of an expanded polystyrene. I like the pattern of it so I decided to try!

Alginate casting of my hand. I like the way my finger prints are on the cast because it seems to be like my own stamp on the work. I think this could be a good solution to put individuality in my product!

Finger prints are also symbols for identity! It would be a really good idea to have consumers' fingerprints on their product!

After a few days, alginate dries and shrinks. The interesting thing is the piece curves from its initial shape.
