Bubbles and possible cracks. As soon as about 20 of those guys work the glass and give the glass their blessing I will unload like a bomb. Looks like I could see 500 slabs in one day period. It's a done deal. I will offer money back for slabs broken due to bubbles if they supply a photo. So far 6-8 spearpoints have been made without issue. The more they post them the better for me. There is no substitute for word of mouth advertising. There is 13,000 on the knapping group. Getting tons of exposure in 1 weeks time. Fast and furious. I could never keep up with them and they are basically an infinite source of willing clients Allison. Awesome. Glass cake  |

Those slabs look fantabulous! I understand your reluctance to sell the slabs until you know whether they can work with the bubbles, but the spears you've already shown all look like they didn't have any problems with it.

I was also thinking that if some master knappers are using the slabs with small bubbles without issues, the slabs with no bubbles would command a higher price. Think this type of slab would be appealing to those who cannot manage the bubbles.
I love your cake.

I agree with Robin
I am sure they know the risks of working with glass
No different really than fractures in a rock slab right? Lots of them work with Obsidian and you cant tell me that is any different.
You can wait for the 20, but who's to say after those 20, someone isn't going to complain about it?

Didn't get a chance to say it, but I LOVE the Neon Tiger!
Although the color combination is the same, the melting makes them all come out slightly different. Much variation in glass. |

::sidenote::
The discussion about the concavity is interesting. Seems to me that the two sided conch fractures would be done at the preform stage. Once the correct proportions are made, the the perimeter is made around them. If the attempts to make the concavities in the preform stage was a fail, they tossed the billet and tried again, and again until it worked.
Having now been to Mrs Kay Nethers farm, I see zero reason why these people wouldn’t have unlimited opportunities to get it right.
I am not discounting the skill factor. I am introducing a bit of luck to the thought process. This should make it easier to consider making new points of this type.

Those points are so nice, you gonna need another saw or three.
The glass doesnt weld to the stainless?

Just had a pro-gun email sent to me by a friend, now everytime jamesp uses a blue Bic for scale in his photos...
I am going to think of this...
Could be worse, he could go back to his colorful eyewear  (He probably will, now that I said that, lol) |

I understand your reluctance to sell the slabs until you know whether they can work with the bubbles, but the spears you've already shown all look like they didn't have any problems with it. Too much can go wrong or be wrong with glass as you know Robin. Even weeks/months later. I'm not rushing it. A few more weeks will tell about this Hot Mix. The glass blower scrap bricks are tested in time and tumbling. They like them too. Ready to sell. The tumbling in coarse grit at high speed tells a lot about the stability of glass. I have a barrel of this Hot Mix rolling. It's tough, not a single broken piece and pretty sure it's good to go. |

Think this type of slab would be appealing to those who cannot manage the bubbles. I love your cake. Biggest concern at this point is the new Hot Mix bricks cracking weeks later Beth. I just have not made bricks until a couple of weeks ago out of this glass, not enough time to have delayed cracking. I think those guys have become comfortable with the bubbles. It really depends on the glass properties and they are saying it is a strong one and the bubbles caused no wandering flaking. It is a bit like ceramic slightly grainy. One of the guys is new to knapping and said it was easy for him. The others described it as easy. Easy is a real good thing. Long flakes was there description. |

I just want to be up front. If I have a good reputation things go well. Chronic complainers in every crowd. Maybe the others will keep them in check. You are right about fractures in rock. Almost hard to find perfect fracture free rocks. The cobbles of the Rio often have fractures from rolling and tumbling. The coral in Florida and Georgia apparently not seen the abuse and large heads have no fractures. Cherts from here too. The knappers have fine rock for knapping around here but lack the beautiful colors and patterns of western rocks. |

Although the color combination is the same, the melting makes them all come out slightly different. Much variation in glass. I left a label on some of the blue shards and sure nuff it formed a crack and messed up a section of the brick. Learned to clean the glass real well. This import frit has tiny metal particles probably from the crusher. It has to be thoroughly washed. Cleaning a big part of the prep. |

Well I for one think it's admirable that you want to make sure your product is fully tested to the best of your ability, even if it means letting it sit for a couple of weeks. You are right to do so. I'm just so excited for you to make a killing with these, I want to rush it. Good thing it's you and not me doing the melting. 
I'll just cool my jets here, watch the monsoons roll in and wait for anticipated updates from the Master of the Melt!

Thanks Robin. I got 2 spearheads in the mail today. Was blown away. Trades working fine. No cost out of their pocket and it looks like I need a large collection of their work. May be better selling the spearheads they make and trading material to get them. 3 - $14 dollar slabs and the spear they send back looks to be worth way more than that in markets around Atlanta. Been cutting and welding smaller stainless glass molds today to maximize kiln space and not melt such large bricks. Eventually gonna send them some tumble finished matching pendants as freebies with the slabs. |
