Frazer and Haws draws its own sheets to control the thickness which sometimes is as thin as 0.6mm. This is only used when silver sheets are required to cover a small area. Most sheets are 2-3mm, going up to 5mm (cutlery). Anything less makes the silver very tinny and dents easily. Silverware available in the market is generally very pliable because thinner sheets are used. Items made from thin sheets may look big but the silver content is fairly low.
