These Cornish Kitchenware items were made by a company called TG Green. The smart blue and white range became very popular by the 1930's and many pieces can still be found at antiques fairs. This display of the china was for sale at an antiques fair in London.

There is a wide range of articles here, with containers for flour, soda, coffee, milk, tapioca, baking powder, barley and sugar.

The white china basin with a lid, at the front of the picture, on the left, is made especially for steamed puddings. You put the uncooked sponge mixture into the bowl, fasten the lid on the basin and place it all into a saucepan half-full of boiling water. This then steams the pudding and cooks the sponge mixture inside. If properly made steamed puddings taste wonderful! A Christmas Pudding is an example of a steamed pudding.

The other white container is for flour.

Do you see the little china blackbirds with their beaks open, behind the flour container? They have a purpose too. You put one inside a pie that you are going to bake and the height of the bird keeps the pastry top of the pie from falling into the fruit or savoury mixture that fills the pie. If it did fall in, the top would get wet and would not bake properly. 

They are called pie funnels and are made in other shapes too. Blackbirds are sometimes used because there is a nursery rhyme about blackbirds being baked in a pie.
