PopSci Shows You How To Make Glass On A Grill, Begs You Not To Do It
Posted by Elaine Chow at 2:45 PM on November 13, 2008
Did you know you could make glass on a regular charcoal grill? Sure it's incredibly flamey and pretty dangerous, but according to the folks at Pop Sci, it's possible! All you need to do is add washing soda, lime or borax to white-silica beach sand and a grill overclocked to reach temperatures of 2000°F. Check out Theodore Grey feeding a concoction of silica and washing room regulars into a cast-iron pot over a flaming grill and getting two pretty medallions out of it. Try to resist doing this at home afterwards. [Popsci]

1:10 reminds me of Sonic the Hedgehog 3 with the fire shield and whatnot.

For a moment I thought this was a repost of one of the previous ones about the flaming balls.

It's amazing what wind and fire can do together.
While this is interesting it reinvents the wheel - in a more dangerous and difficult way at that.
If I want my own trinkets I'll find a local glass blowing shop and pay them not to burn nor melt my metal gear. (pun intented)

I'd rather not burn down my garage, thanks. Although it would be great for thawing out those dead bodies stuffed in my meat freezer; not to mention incinerating the remains. The hemi-powered wood chipper hasn't been to gracious to the neighbors.

Man that looks like a bad idea for your average DIYer. Now where's my grill and 20 lb bag of charcoal...

Who cares about some cheesy glass trinkets. The only thing that *I* learned was that adding a vacuum cleaner to a grill will MELT THE GRILL. Hmm, I wonder if I can grill up a nice sword or something.

@FedExin: I think you should take it away. I went to my parents house for a BBQ not too long ago. It was a pleasant Sunday afternoon when my father went out to start up the BBQ.
Here is a short transcript:
Dad: "Holy F@ck! Gawd Damn it! Oh WTF!"
::WOOSH::
(scurry of neighbors with fire extinguishers)
Dad: "Piece of cr@p BBQ"

@latterman: Gold and silver melt at fairly low temperatures. A golden coin using the above mold would be pretty cool, if pricey. ... Very pricey. Hell, just buy a gold coin.

My Dad has recently gotten into BBQ. I think I can convince him that this is a good idea, somewhat along the lines of smoking salmon, no?
Honestly, I've always wondered about this one. Cheers to Popsci.

While glass isn't really feasible to make on that, you could easily make your own copper items in it.

Well, I suppose if someone stupid enough to take a ball of molten glass at very high temperatures close to an expensive Mac on top of a wooden board was able to do it, lots of people also can.
Just try not to abuse your luck like this guy did.

I don't know if I would use a regular grill to do that.. with you know the high temp and melting and all. I would have at least reinforced it. The legs, the actual grill.
I mean the last thing you would want to happen is the grill to go tumbling over from high temps and throw charcoal and molten glass around..(I actually don't know if that would happen, but with the high melt skin off your face in the blink of an eye temp, I would work to minimize any risk down to zero if possible)

I want to know where to get one of those claws. I regularly melt aluminum and glass in my fire pit, but getting close to place items into the heat is a problem. This would work great!!!

Best part was the line "Oh you know what that is? That's IRON!" I laugh at them for melting an iron skillet. Haha!

They exposed themselves to all sorts of potential disasters and then posted it so other people could do the same?!?! Those people are idiots...plain and simple.
This would be much safer, effective, and hotter if they simply used $10 in fire bricks as a liner with an old coil from a stove (tungsten) to support the charcoal. Hook up a blower like the one they used and one can easily make glass. OUTSIDE of the garage!!!!

ok, seriously... DO NOT USE A GRILL IT WILL MELT!! instead go to home depot and get a terracotta pot a big one!! place it on some bricks (concrete cinder blocks) and leave the hole clear.
this is a lot safer!! my dad showed us that when he would melt all sorts of crazy stuff with thermite (he had lots for work for some reason)
takes a while to ignite but ohhh baby did that stuff burn through just about anything!!

Neat video, but I guess I was waiting to be dazzled by the final product. It wasn't very pretty, and the glass didn't look that clear.

Its really not that hard to melt glass - most pottery kilns reach the sort of temperatures necessary. Put a soda bottle into a kiln, heat @ 1700 for 30 minutes, and you will end up with a 'puddle'. Its quite easy to build a natural gas or propane fired furnace that can accomplish the same thing using an old beer keg lined with frax or refractory soft brick. Terra cotta flower pots can be used as cheap crucibles to contain the melted glass. With some ingenuity and access to a reasonable scrap yard, you could build all the equipment necessary to work glass. Combustion train components can be built out of pipe fittings, burners can be cast...

and what about those hot droppings onto concrete? nice little area of pits. plus there should have been a sand pit to work on.
