TierraCast Casting Alloy:
Your Assurance of Safety
TierraCast uses “Britannia” casting alloy for all cast pewter findings. This alloy containing tin, antimony and copper, is considered “Lead Free” by the metals industry and the jewelry trade as it complies with the USDA standard of less than .05% (or 500 parts per million) lead content in pewter in contact with food.
The following table lists TierraCast’s most current purchases of this alloy for use in our products. It includes the date of purchase, the vendor from whom the alloy was purchased, the lead content expressed as a percentage, that same percentage expressed as parts per million (ppm) and the testing certificate number for that lot.
