Let's assume that the silver load in FB paper is somewhere around 2g/m2. Spot price of silver today is around €1/g, but let's say in reality Harman pay a little more due to the combined effects of additional costs, also because they use silver nitrate instead of raw silver, and put this at €1.50/g. That's around €3.00 per m2 in cost of silver per m2 of FB paper. Here in Europe, MGWT costs something like €36/m2 retail excl. VAT. You can figure out what an increase of let's say 50% in silver price does. Mind you, it does a lot more to Harman than it'll do to you, because the first part of the retail price buildup that gets eaten is Harman's own margin.
