Reflection

Overall, I was happy with how my plaster piece turned out. I found it to be a quick and easy way to create a mould. However, next time I do this, I will make sure to tap the side of my mould to ensure there are no air bubbles.

I don't think that this is a good way to create sculpts in industry due to all the disadvantages that come with it. The main one being it breaking, you need something that you can take travelling with you.

However, it is good for a low

budget production.
