Transcript of Pewter Casting
Pewter is made of 85-95% tin, 3-7% copper, 2-7% antimony, 1% bismuth, and sometimes 30% lead, 1-3% zinc
You will be creating a pewter casting, it is up to you to decide what its possible use will be (pendant, keyring, dog tag etc.)
You will need to write a design brief
You will need to write a profile for the user
You will need to create a mind map to help analyse criteria for the pewter casting
You will need to design your pewter item with annotation
You will need to write a specification once you have decided what you will make
You will need to develop your design and recreate it on 2D design
Is an alloy metal, an alloy is made by
combining two or more metallic elements
A kilogram of pewter usually
costs upwards and above of
20 pounds per kg
dependent on purity
Pewter manufacture can be divided into two categories-cast and spun. Pewter can also be manufactured by
Metal Smithing-solder together the component parts.
Spinning-placed in a lithe and spun quickly.
Buffing-Applying product on a rotating mop which buffs it up
Polishing-Applying product on a rotating cotton mop with oil to give it a polished look
Pewter is often used for household items such as (plates),decor (candlesticks), and jewellery (cuff links)
Pewter looks a lot like silver but has a darker appearance. Pewter is often much harder than silver and is more durable.
Pewter has a melting point of 244C to 295C with a combination of metals its properties may change slightly.
First appearance was in 11th century
Pewter is one of the oldest metal alloys.
Pewter ware popularity decreased with the introduction of porcelain
