Economic issues have required changes

As you may have noticed, we are no longer selling cerium oxide. For about the past six to nine months, the world-wide supplies of cerium have dropped significantly. This is due to export restrictions placed by China on raw materials. They have also placed rather large tariffs on all outbound shipments of some of the more “precious” raw materials. The combination of factors has caused our cost to skyrocket by 750%. Needless to say, we no longer have excess polish that we can afford to sell.

About the same time (roughly six to nine months ago) Schott in Germany shut down their welding glass (float glass) manufacturing processing plant. This was due (they claimed) to low demand for the product. Schott was the last large-scale manufacturer of welding sheet glass in America/Europe. The last of the Schott glass is gone from our supplier, and they are currently trying to get glass from China. This has lead to a shortage of sheet glass in shade 4, 5 and 6, which has also hit us.

We are starting to work with the Chinese glass, but it has some drawbacks, mainly an apparent color difference. Schott welding glass is grey-green in appearance. Chinese welding is yellow-green in appearance. Therefore, we will no longer be able to replace single lens units in any of the AGW-250, 286 or 325 filters, they must be sold in pairs so they color match. This will *NOT* be covered under our warranty.
