What we had to do
We were asked by the Australian company The Chia Company to make some giant versions of their pots of chia dessert and of a packet of their seeds to help promote their brand in the UK. The pots had to be clear with the pudding inside and branded vinyl packaging.

The polystyrene potWe sculpted the pot in polystyrene as we were able to mill it in to the pot shape. We sealed the polystyrene, sanded it smooth and took a mould from it
The polystyrene lidWe did exactly the same for the lid as we did with the pot. Once both have had moulds made we can cast them in fibreglass and vacuum form them in the clear plastic ready for the spoon and vinyl seeds and labels.
The spoonHere you can see the underside of the cast fibreglass spoon beneath the clear vacuum formed lid. We painted it orange as per the original.

How did we do it?
We had to sculpt the initial shape and we did this with polystyrene because we knew that it would be an easy material to work with. We set a block of polystyrene on a turntable and spin it whilst shaping it, much like a lathe, to give a perfect pot shape. From this we made a mould and cast a fibreglass master. The master had to be very strong and take tons of pressure as we would be placing it in an industrial sized vacuum former to form clear plastic over the shape, resulting in clear plastic replicas of the pot. Before we could do this we had to sand and finish it to a highly polished surface, making sure to sand out all blemishes and undulations. The lid was made in the exact same way, which also had to be vacuum formed in clear plastic. There is a spoon supplied on the underside of the lid of the original pots so we had to be true to this and make a giant version of the spoon. We sculpted this in clay and made a mould so that we could cast three of them to go with the three pots. We had to find a way to make the clear pots look as though they were filled with the Chia product, but making the seeds would be too costly, and sourcing actual seeds wouldn’t work because of the large size of them scaled up, so we had to print an image of the seeds on to conformable vinyl which we could adhere to the inside to look like the real thing. Firstly we had to take a very high resolution image of the seeds and use our local printer to print on to the vinyl. Luckily for us we work closely with a number of local companies, and one of them is used to covering jumbo jets, cars and buses with conformable vinyl so our little pots were easy for them.
The pots really looked the part and our client loved them.
