HI again Sasha !
Here are the answers to your first questions !
What thickness metal did you use for the beakers?
> The beakers are 10cm in height, 8cm wide at the top and 3cm wide at the base. They were made from a disc of 17cm diam metal which was 1.2mm thick. They look thicker at the top once they are spun because the action of spinning pushes the metal up to be thicker at the rim. The top rim measures 1.5mm. The thickness graduates back to 1.2mm towards the base.
What metal did you use?
>The metal is Britannia Silver. This is good to enamel and more importantly easier to spin for the silversmith as it is a softer alloy than standard silver.
Were the beakers forged or cast?
>They were spun by http://www.silver-spinner.co.uk/
Here are some photos of how they where made. I haven't had time to arrange them in order but I think you can work out the progress......Each beaker was engraved to give texture to the metal, then enamelled in various techniques using transparent enamels. I used a flux Blythes C1 as a first coat to ensure it covered the entire surface before I commenced the colour work. It is ground very fine and I add a bit of klyre fire to enure the enamel stays on the vertical surface. I fire the pieces upside down on a ceramic fiber board which has a hole cut away to the same diameter as the top of the beaker, so as air/heat can get inside the shape.
The ceramic fiber board is also useful to catch powder if any drops down so it doesn't affect the kiln floor.
I anticipate your next set of questions !!! ..................
