Corning Batch

Hello, I am considering switching from spruce pine batch to Corning batch. Spruce pine has just become too expensive. Does anyone out there melt the Corning batch? I am just wondering what people think or if there are any compatibility issues with reichenbach colors. Thanks!

Here's a thread I remembered from a few years back. If he's still selling that maybe watch out for the soda bloom, and the fluorine especially if you melt in an electric.

I was going to refer to the exact same damning thread that Josh was. There are numerous other people who have had seriously low opinions of the company and they could be found most likely using the search engine.

If you want a clear that I think costs less ( I don't know that but it should) you could have them mix the VDL Clear that I wrote for SP a number of years ago. It comes as a snowflake version. It does not contain any lithium which was part of the directive at the time. It is a very easy melting clear, it's dead on 96 and sits on the SP specs in every way. It does NOT devitrify. It has a far higher luster. It polishes much better than SP. John Croucher sang high praises of it when he was still alive. I use it whenever I melt.

Thanks guys for the link. Saving a few dollars does not seem worth the hassle of remaking work for customers. I called Spruce Pine to ask about the VDL snowflake batch. It is the same cost as the spruce pine plain batch.
I like Josh's idea of a class for clear batch. If you run it I can fill two spots in the class.

I don't have the facility I had when I ran the last color classes almost ten years ago. I could certainly lecture on the subject. I could potentially do a class at Penland as a possibility that could include melts. I'm an old guy now without the requisite energy to take on the physical aspects of lugging stuff around.

I am not surprised about the pricing of the clear. Back when I wrote the formula, Tom didn't like it because it did not cost less than the existing SP87. So, now, it apparently has the same price as the stuff with lithium but I am guessing, no erbium. The expense in my glass that was notable is potassium. It isn't that prohibitive to use as to costs.

It's a great glass, again, it doesn't devitrify and has luster. It's very nice to work as well. Better stuff. I don't get rich off of it, that's for sure.

This has me wondering about any batch that doesn't get pelletized, including my own homemade mixes here. I've been mixing about 50lbs. of ingredients that are just about all powder consistency, the afternoon before throwing it all into the furnace. This melt I just did yesterday, I'd mixed two days ahead of time but was concerned that things may have "settled" with that extra time lag so I tumbled everything around in the mixer again for 15 min. before charging. But is this a valid concern? I do usually melt everything that's in my mixer, so maybe that helps, but makes me wonder what might be an issue if I bought some really well-mixed stuff from SP but it was hanging out in a bag for a couple months until I get to it and then maybe I don't even use the whole bag for the last charge. The pelletized stuff seems like it would help keep ingredients from separating, although I realize SP can vary on how consistently it's pelletized. Glasma is super evenly pelletized from what I've seen of it.
