Good link! I'm torn between surrendering to the surface haze and embracing the frosty look (or enhancing it with acid polish/sandblasting), and finding a way to get rid of it.
I've taken the thrill ride of grinding smallish flatwork on a horizontal lap, and, being a fundamentally nervous type, I don't recommend it for the faint of heart.
For those who absolutely can't stand polishing, you can "cheat" by spraying the piece with crystal clear acrylic (not sure how this looks on flatwork, I've only done it on cast pieces). Obviously, acrylic spray paint will not handle the long term (decades to millenia, which properly handled glass can last into). So, hand polishing may be the only way to go. I suppose one needs a sense of perspective here. Those crystal skulls from Mexico were multi-generational polishing jobs - grandpa started with river sand and water, dad took over, son finished it up.
I also am reminded of the Libyan desert glasses, which have been lying around buried in sand for upwards of, what?, like 20-30 million years, and still look fire polished (recipe: take one giant meteor or 6 megaton H-bomb, explode above sand bed, allow to cool over one thousand years).
You have to consider not only how much effort you have put into the piece, but just how long this piece you made will last? A few hours or days of hand or machine polishing seems like no time at all for something that will outlive your great-great-great-great grandchildren.
