The economics donít seem to be working out either. Working temps are higher, washing out any energy saving from not melting batch. Couple that with more expensive glass to start with and higher maintenance cost, it means that Iím switching back to SP87ER after this pallet is complete. A failed experiment in my opinion.
Ouch.... thanks for the info. I guess that I will make the switch back to SP batch after I am done with my cullet....
