Jim, if im looking at that correctly the color doesn't go all the way thru the glass? Looks clear under a thin layer of color? This is true. Some machine injected a balloon of colored glass down the center, inside of the balloon full of the same clear glass as on the outside. Fooled the heck out of me. Because it was a total balloon there was no way to tell it was a thin layer of color and not running full depth. So I had to bust my butt hammering the color out of the clear. Not really a problem, a small patch of color in each chip seems magnified throughout each piece. They even injected a thin layer of opaque white glass behind the color layer to block your view of their treachery lol. Why do you ask Alison ? Is this the work of a machine made counterfeit to a Murano ? Or would the Italians do the color the same way ? Me uneducated about glass. This piece lacks bubbles(which I prefer for tumbling): "5 Identify evidence of a hand-made piece. Murano glass is hand-blown, meaning there should be bubbles and asymmetrical qualities.[4]" This is a cross section of the thin section - the rooster's neck. You can see the 'balloon': This is a good lesson in fancy glass. A real Murano, Blenko, Fenton and some other makers that hand blow glass, this piece would of been colored solid. Each layer of coloring. Incredible workmanship. This rooster is a mold, then a thin layer of coloring, probably a dye. Being a mold, youll also have less bubbling. It will be interesting to see how the colored portions hold up.

youp50 and grumpybill Such activity must take place at great distances from the better half. Or a sound proof man cave with a secret ingress/egress and large padlocks. Or better yet when she is way out of town. Of course you guys already know that. I have said man cave, heated and blocks from the house. Storeroom lock on the door, alas, CRS kicked in and I needed to give the Mrs a key. So I can access the shop when I can't remember where my keys are. I was told 3 things go when one ages. 1) eye sight 2) hair 3) ......gimme a moment, I forgot #3...

One guess where those are now ; ( www.cmog.org/ -Type in the search bar for Ruby Gold Macbeth-Evans Glass Company is one that I have not been lucky enough to get my hands on and also would love some Pale blue Uranium Glass With the invention of Ebay and certain TV shows, these are getting harder and harder to come by Georgia has some pretty amazing pottery that you should also keep an eye out for.

@alikat, my buddy I was raised next door to as a kid, his Mom was 5th generation potter from SE Alabama. Several families actually. She had a whole houseful of clay. Best of the best. Passed downs. My buddy hated the stuff. when she passed he hurled all of it into a dumpster. Collection worth a fortune. Told me after-the-fact. Some of those pieces well over 10 grand. #@$%^^
"Curator Dedo von Kerssenbrock-Krosigk describes this goblet made of gold ruby glass. Gold ruby glass is one of the most difficult colors to achieve in glass because it consists of gold that has been added to the solution of the glass, where it dissolves into small particles, so-called colloids, during the heating and forming processes. Colloids have to have a very specific shape and an equal distribution within the glass in order to produce an even ruby color. The principle of coloring glass with gold was probably known since early antiquity, but Johannes Kunkel was the first to achieve the difficult process of producing very large gold ruby glass vessels. Unfortunately, the foot and cover of this vessel are missing, and its surface is crizzling. Crizzling is a process of crystallization and deterioration of the glass that derives from a mismatched glass batch composition and is characteristic particularly of the early stage of baroque glassmaking in 17th-century Europe."
I just ordered a microwave kiln on Amazon to melt some glass for the tumbler. They melt glass in minutes.

I tell her not to be so flippant about it and that she could sell it all and buy 2 of the houses we live in and have enough left over to furnish them. Think she says such to get my goat. I explain that I won't be in any position to care what she does. That usually shuts her up. I hope she enjoys selling rocks! A grand posthumous haunting scheme by means of minerals. *grin* Your buddy was a dumbass just throwing money away like that. Wonder if there were underlying issues.

What’s one person treasure is another persons junk. He prob grew up around it and just didn’t care about any of it to try and resell or hold on to.

jamespWhy couldn’t you use sand and 220AO in the vibe? Seems like if it were they quartzy type you could do something... just a thought

Mr Vick pretty much divorced her for the hoarding issues. The house was so packed with pottery it looked like a messy museum with a path. And I bet Steve got chewed out for breaking some of the pottery when he and little brother were wrestling in the house. Steve could have placed one call to a pottery auction house and they would have quoted him a fat price and hauled it off. Nope, he wanted to destroy it, no doubt.

jamespWhy couldn’t you use sand and 220AO in the vibe? Seems like if it were they quartzy type you could do something... just a thought Your talking my language. 1/2-3/8-1/4-1/8 and then sand. I am at 3/8", next size is 1/4. You may have to increase the vibration strength on smaller media. Get down to 1/4" to sand and the abrasive may likely not break down never achieving polish. The 3/8" media took longer to lay polish than the 1/2 to 5/8" gravel. No doubt the added contact points reduce pressure. This is how I am separating 1/8 to 1/4 inch high grade quartz jelly beans from the trash in this fine mesh aquarium gravel Jimi. The rounder quartz rolls down the ramp to the bottom, separated from the trash at top The trash in this mix is mostly harmless limestone. Slurry maker till it grinds away. High quality tiny media, lots of jelly beans

I think I just had a heart attack-unfortunately it isn't uncommon ; ( on the other hand-a kiln ...oh my check out the kiln MsAli lisp. About $50. I can't melt glass with my torch this cheap. Seems a bit hoax-y but I have like red glass that is very valuable but to thin. I can make fatter blobs with this unit. Then tumble. or mix marbles/colored glass for effects.

I was reading up on microwave kilns not too long ago. The principle is the silicon carbide layer in the kiln absorbs the radiation from the microwave generating enough heat to melt things like glass and gold. How well it works would likely depend a lot of the power of the microwave.

On a recent trip to the Coast we stopped @ The Glass Forge, in Grant's Pass, OR and watched some glass blowing going on, and I got curious and asked what they did w/ their broken glass. Well in addition to fashioning trinkets and baubles and such from the breakage, they did have a bit they were willing to part w/ @ $5/lb. I donned some leather gloves and went a-rummaging, pulling out a whopping 3 lbs. (the rest was small shards). Once the weather thaws again, I'll drag out the tile saw and chop these up for pendants and earrings.

Apparently the layer of silicon carbide traps the heat vegasjames. I ordered a 7.7" diameter kiln, a bigger one. Amazon for $52. Apparently it will have to stay in the heat longer than the smaller units. Maybe 3 times longer. It takes an acetylene torch a fair amount of time to melt a marble. Much longer than 3 to 8 minutes. And costly. Especially considering the slow heat up time to avoid it shattering. The microwave radiation must heat equally inside to outside to melt in 3 to 8 minutes with out shattering. I also bought a $50 1000 watt microwave brand new discounted at a thrift store. They had dozens and all types/sizes.
