- Final casting from the mould that contains the original model's negative.
My original idea when i first heard of the assignment was to create a 'breakaway' glass bottle like the ones used in practical effects for film and TV. Part of the process would be done using a 'rotary casting' machine like [Paul Cairns](http://fabacademy.org/2021/labs/vancouver/students/paul-cairns/assignments/10-machine-building/ "Paul Cairns -2021 Vancouver") (2021 student from Vancouver - machine week).

Milling the outer profile of a bottle in a 2 part mould, i would add a small amount of material into the mould and then spin it in the casting machine to create a seamless hollow bottle. But without a rotary casting machine being accessible, i then change the idea to creating half a bottle in 2 parts (outer profile and inner profile). From which i would cast a half bottle twice and fix them together somehow.
