 ENGELHARD
 
is pleased to welcome visitors to our Thorne Mining & Refining Company Definitive Page. While our focus is clearly Engelhard, we recognize that many Engelhard bullion collectors also collect other bars and ingots. As such, we appreciate the opportunity to present additional collections and look forward to your thoughts and input!

Additional information will be forthcoming as we expand our Other Notable Refiners database.
