"Their colours depend on the application of the glaze. I found that those with only a light glaze have more green on them, while those with a heavy coating of glaze are more purple-blue," Mr Vostinar said.
He described the collection as being like sketches in clay.
"The intention was a free outpouring of ideas expressed in a minimalist way and on a small scale. There was no preconceived idea, only that they were all to be humanoid in shape, creating a mass of humans swarming and cavorting.
"It was a challenge to do 100 completely unique forms - but I thought 100 was a good number to aim for. I started off really well, but after about 20 I ground to a halt. So then I had to go find some new ideas," Mr Vostinar said.
"They're small, they're quite simple, but I can feel chuffed that there's enough variety and enough interest in them."
Mr Vostinar said he would like to explore some of the shapes on a larger scale.
"In time I will do full kiln-sized versions of some of my favourites," he said. All the sculptures are for sale, ranging in price from The Creator at $400 down to Pimp Squeak at $30.
