materman Posted February 17, 2019 Share Posted February 17, 2019 Had a question I would like to ask if I may. A friend gave me about a dozen catalytic convertors that he said one buyer only offered $5 apiece for and others wouldn't buy them period. I cut one apart to get a fill for there contents and found a nice block of honeycomb like material. I wanted to ask your thoughts as to whether it could maybe be cut into bricks for lining a forge or grinding up to make refractory for a smelter? The stuff is supposed to take some pretty high heat and thought I would post here to get your guys thoughts. Thanks for any input. Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted February 17, 2019 Share Posted February 17, 2019 The materials inside a catalytic converter are quite valuable, you would be better off stripping them and selling the metals. https://www.google.com/search?client=firefox-b-1-d&q=catalic+converter+materials Link to comment Share on other sites More sharing options...
materman Posted February 17, 2019 Author Share Posted February 17, 2019 Most convertors are worth money and he does sale the ones that are. But these are like a pre cat. Out of some diesel cars he parted out and the buyers just don't buy them, or only for $5. I figured they might be worth more then that as bricks or refractory, but just wanted to through it out here for people's thoughts. Link to comment Share on other sites More sharing options...

ThomasPowers Posted February 17, 2019 Share Posted February 17, 2019 Unfortunately "being able to take heat" does not necessarily make a good refractory for forges or smelters (BTW what ore were you planning to smelt? Different ores require different temps.) Insulative qualities make a major difference as well. Take the US$5/per and run! Link to comment Share on other sites More sharing options...
materman Posted February 17, 2019 Author Share Posted February 17, 2019 I had the thought of cutting and sealing the ends so that the little squares in the material could theoretically work as dead air spaces. Figured i could mortor them back together with something like matrikote for this is what it looks like they used before, and then coat the whole inside. Figured combined with ceramic wool it might work great for a standard gas forge. Link to comment Share on other sites More sharing options...
Frosty Posted February 17, 2019 Share Posted February 17, 2019 Take the $5 and buy some real refractory. Frosty The Lucky. Link to comment Share on other sites More sharing options...
