  1. NSP, Silver refining to separate lead from that silver has been done for millennia before the Romans. There is evidence of such activity that dates back to 3,000 to 4000 B.C.E. in Anatolia. The process is called cupellation. Base metals oxidize much more readily than base metals such as lead. (copper zinc etc.) and that allows for cuppellation. The mix (solution)?) is heated to a high temperature and air is blown into the mix. The lead is oxidized and gassed off leaving the silver behind. Scientists have found lead peaks in glaciers that correspond to the time of the Greek'
  2. Mr. HWBX, I looked up 'mudlogger' for you, Bing says that it is, “Mudlogger” is the generic term used to describe the field specialists who monitor the well and also collect samples for the geologist. The career progression for a mudlogger is to generally start as a sample catcher while they learn about the drilling operations, then progress to a mudlogger and with further experience, become a data engineer. All that I do is to type in 'mudlogger' def. And Voila, SLAG.
  3. Mr. Sells, (a.k.a. , Steve), We are both correct. With, perhaps me being somewhat inarticulate. There is some included carbon in most iron due to the heating and carbon monoxide reduction of iron oxide, in the process. Regards, SLAG. I just checked Wiki, it states that pure iron is ductile (it stretches), and is not very strong.
  4. Mr. Sells, Are you intimating that bronze is as strong as steel? Quenching makes the iron harder*, but extremely brittle, and the subsequent tempering essentially trades some of that brittleness to a softer condition but much of the added strength is retained. When iron began to replace bronze for "swords" there were still plenty of bronze implements being made, for other purposes. Regards, SLAG. p. s. the crystal structure changes upon rapid cooling, which drastically changes the properties of iron.
  5. Folks. Iron is as strong as bronze. But iron that has been quenched and then tempered, is much stronger than bronze. Iron replaced bronze slowly in the near east. But it was in use there as early as 1,100 years B.C.E. (with the Hittites and other cultures). The Egyptians knew how make iron and use it. But they did not replace their bronze weapons until after the Assyrians conquered them in 661 B.C.E.* At about that time the eastern trade routes to Iran and Afghanistan (and also the sea routes to Cornwall England), were disrupted and tin became very hard to get.

    Mr. H.W.K. B.X, Wrote and I respectfully quote "I was more being a smart xxx about that, but you make a good point. Only problem is I'm in Canada so that usually kills any of these forum deals." You will never definitively know that until you click on the "gas forge supplies", button on the top left of the page, in the shaded blue banner. Alternatively, you can private message the site owner, Mr. Glenn Conner the vendor and Grand High Panjandrum of this site. (i.e. I.F.I.). I hope that helps. SLAG.

    Mr. HB., Are you aware of the cost of Colgate toothpaste? it would probably be exorbitant Mr. Glenn would happily suggest something cheaper and more effective. He deals in such goods. (and you could order it on line, from this site, even). Failing same Mr. Mikey and/or Mr. Frosty would, probably , 'come through' with a suggestion. Helpingly, Yours, SLAG.
  8. Steve , Thank you for the pictures. Clever. Nice set up. SLAG.
  9. JHCC, Has cogently suggested, that "a leather welding jacket is good for shop work in the wind and the cold". Similarly the SLAG has resorted to the combination of a down vest covered by a loose leather jacket, also, works very well in cold weather. The Good Will and Saint Vincent de Paul etc., etc., stores frequently have many such leather jackets for a very reasonable price. Regards Ya'll, SLAG.

    Mikey (effendi), Thank you for the useful information. I was just curious when I posted that response. Regards, SLAG.

    Mr. Mikey, Carboxymethyl cellulose is water soluble. The organic acid moieties (OH-C=O) make it water soluble and reactive. It is even used in toothpaste formulations, etc., etc. Would that preclude its use in gas forge linings? SLAG.
  12. Mr. George N.M., Your two posts, situated above this screed essentially describes the "Parito Principal", but with a vengeance. Namely about 20% of the population commit 80% of the crimes and other commotion. But I believe that you 90%-10% figure comes closer to everyday reality. Alas I never had the opportunity to become a prosecutor. Patent lawyers do not seem to make the grade. Feedback, though rare, is really very gratifying. Regards, SLAG.
  13. Mr. Steve, Stash, Could you post a photo of your Ikea CD rack? Thanks. SLAG.
  14. IDFC, You are right. I missed your post. (above) Sorry about that. SLAG.
  15. Pnut, and Mr. L.B., Is correct. Mesothelioma and silicosis are horrible diseases to contract, and most probably die from. There is a thread concerning such disease caused by particulate contaminants. I believe it was started by a member, a smith and doctor that specialized in such maladies. Look up chuck wright on the threads on this site, to get a lot of information and grisly pictures of a young smith that unknowingly exposed himself to gas forge flaking materials.* I am too lazy to repeat the extensive correspondence details, here. Look them up and avoid killing yourse
  16. Das, You are a champ. Thank you very much, for your prompt and informative reply. Regards, SLAG.
  17. Herr Das, Has stated concerning cutting and or drilling stainless by writing, " ... or buy the really good drill bits ..." Are you referring to cobalt steel drill bits? Hope to hear from you in due course. SLAG.
  18. Herr Frosty, I mentioned that both crazy glue and epoxy resin were resorted to in emergency surgery in the Vietnam war. Cyanoacrylic (crazy glue), was eventually adopted for common surgical procedures as it is not as corrosive and allergenic as the epoxides. Epoxides work. I have used it on myself to mend cuts. But crazy glue is preferable. Crazy glue usually cures in the tube after only a little while which is a real pain, when you need quick). Indeed water vapor drastically speeds up the reaction. So tubes on the shelf usually cured and do not work Crazy glue in the firs
  19. Mr. Chimaera, Old iron tools, and parts are frequently made of wrought iron. I bought a batch of it, from a smith on I Forge Iron who got it from the demolition of an old bridge. Mr. Powers has mentioned that he frequently procures it from old wagon tires. In other words, wrought iron is out there you just need to learn to recognize it. SLAG.
  20. Mr. Frazer, Much of those "slag inclusions" are iron silicates. Hammering the iron forces some of that silicon out of the mass of iron. The more that mass is hammered the "purer" the iron becomes. Highly refined wrought iron frequently underwent three separate heats, and a lot of hammering, hence its cost. And yes it is a joy to work with. SLAG.
  21. I.F.I. Smiths, Building inspectors are not above the law and so that they can do anything they please. They are bound by building codes just as we are. A newly instilled inspector cannot, by fiat, (on a whim), change the rules and interpretation of those rules in a dictatorial manner and thus change the original inspector's interpretations, and requirements. The applicant is not at the mercy of that 'new' inspector Your discussions and the determinations and information by the original inspector do not automatically expire when the new inspector takes over. The for
  22. Mr. ST-SK, Thank you for the fascinating and erudite information in your post I found it a most interesting and informative explication of runes on some smiths' pendants. SLAG. (the pagan?)
  23. Das, You are right. I mixed up chain saw protection with cut resistant gloves, finger covers tape wraps, etc. And was not specific and clear enough. (i.e. comingling two ideas). There are plenty of types of the later. gloves, including leather. And I have several. (many for specially designed for hand wood carving). But the gloves tend to be bulky. and that is why I bought the chain mail gloves many years ago. even though they ARE expensive. but, then again they should last a lifetime. Cheers, SLAG.
  24. Mr. Chimaera, And Das et al., I was referring to anyone who has experienced a cut. Epoxy resins were first to close up incisions and debrided wounds, in field hospitals, in the Viet Nam war. It first used by some creative surgeon, as a jury rigged on the spot fix. Specialized epoxy resins are still used for that purpose today. the preparations are modified because the hardener/accelerant is somewhat corrosive. For that matter, crazy glues are also used for the same process. Herr Das is correct that other types of cut resistant gloves can be used. For example I have cu
