To make a bone china rose you dont need any tools except oil to dip your hands into to stop the bone china sticking to your fingers. You can see my video of how to make a bone china rose here or further down the page.
To make most of the other flowers basic tools are used. The comb is used to create spiky effects (see below) the sieve is used to make the center of flowers. The mold with lines on creates lines on petals, the leaf mold obviously creates leaves, and the other tools are used for different techniques. The grey metal card (an old credit card would do) is used to cut the clay when needed.
Below are the tools we use at Coalport China Museum.
