Thank you Hank. :) Now I have a lot of free time, so can do what I'm interested in. And of course, feedback is very important. Your comments always encourage to make more. :)
Thank you Wolfbane221!
You're right Ihuizinga. You should try. May be it's not an art but I feel good when I create something. :)
Thank you Thepinnacleofcynical. I'd like to recomend you my other videos which I mentioned in the first paragraph. It was even harder for me to make those things.
Casting Aluminum. A SaucerView Instructable »
Hi camalo171. I use gasoline torch (blow lamp). It allows to get high temperature and very quickly. You can see black round handle on the torch. This is a handle of a small pump. It's used to pump the air and make a pressure inside the torch. That's how it works.
Thanks for the like on Youtube Hank! :) You're definitely right. Lead of course is a very heavy and density metal, so it damages matchboxes not only because of temperature. I thought about what you said before melting but decided that there was no need to make them very beautiful :). Though you suggestion is right if it's important to get precise form.

Thank you Ironsmitter. Your information is very interesting and useful.You're right, I didn't check greenhouse type stores. That's a good idea. Aboutother stores... Types of products which are sold can be different because ofthe country. Yes, of course, now we have globalization and the world becamesmaller but some goods can not be used or at least widespread in a particularregion except some common basic products. Now, I use only handmade steel crucibles for aluminum as well as brassmelting. I will definitely need a graphite cruciblewhen I try to melt iron. Thanks againfor your tips.
Thanks for you receipt. Could you share how much vermiculite did you add? Of course theory is important and I read about some working formulas. My idea was to use ingredients which are easy to find. Such things as perlite and vermiculite are not sell in next door shop and even in supermarkets in my country. The stuff you mentioned could be bought only through the Internet or in some exclusive shops. My idea was to use widespread materials. I will definitely write if my final formula is bad and doesn't work in the furnace during real melting. P.S. The only thing which is not widespread is graphite dust but it's produced near my town, so it wasn't hard to buy it :)
Thanks Hank. I really appreciate you words. :)
Thanks for you comment. You're right. I used both products because grog didn't contract (shrink) in contrast to fire clay.

In my opinion, there is no need to cover it with chemicals. Of course, after some time it'll be covered with patina but for this thing it's good as well as for coins. :)
Thanks for the correction. As you understand I'm not a native speaker, so I can easily make a thousand mistakes. :)

Yep wsmwsm. I understand this. My purpose is to find the solution where I wouldn't have to wait too long. :) And as you see the result is similar even for materials such as alabaster which becomes solid very quickly. That's not a science of course, just an experiment :) For the second experiment I will use other materials and an oven to dry samples better but enough slowly to prevent damages.
Thank you very much Hank! Just try do to everything step by step. :) I hope that you're right and some of my home experiments will be useful for others. I saw a lot of videos where people said how they did some things but didn't say, that for instance, furnace made of plaster and sand would be damaged after first melt or the most after several times. It's good to find out that something doesn't work before you spend a lot of time and money :)
Yes. It's enough old thing. :) Nevertheless, still works fine.
I'll do my best! :)

Thanks for your good advice ChiGuy14. I can say that now I totally satisfied how my green sand works. I used it many times, so it's not bad. Also, I've got some bentonite clay from open-cast mine near my town. I will test it to find out if there is some difference. You can also see how this green sand formula works in my other casting instructables and youtube videos.

That's good. I do the same. Just throw away very thin layer of green sand which contacted with melted metal. This sand is black, so I think it becomes bad binder.
That's grate that you have found the solution. At first I thought that I could buy some clay in shops which sold building materials. I was suprised to find out that nobody sold pure clay. :) Does your green sand allows to use it many times. I mean there is nothing left which can just burn during casting?
Yes. I see that a lot of people use cat litter as bainder. The only problem that cat litter may consist of different ingredients. For example, I didn't see cat litter which is a good binder in my country. I usually buy for my cat, some cat litter which looks like wooden pillets! Before I bought cat litter which consisted of silica gel. I assume that I can find some other sorts of such things through the Internet or in big supermarkets but it's easier to dig some brown clay :)
Yes. It works good. As far as I know when we use bentonite clay, than 13-15% is enough. But with brown clay 15% doesn't work. So, I took twice more and it started to maintain a form. I also got some bentonite clay, so will try it in the future. I'd like to understand if I could notice some differences.

Surely if we use plaster mold and a purpose to make a mushroom it will be much better. I just wanted to show that sometimes you can use material which was left from your casting. From a meter or two you just won't see ribs anyway... You can see the difference only from much closer look.

If coal a problem inyour state than maybe try to search coal or charcoal briquettes. I think that even charcoal briquettes will work much better than simple charcoal. If this is also an issue than I think propane is a good alternative.
Thanks Indromac. Yep, that's charcoal + coal (black coal or hard coal) + air = brass ingot. :) I couldn't rich enough high temperature with pure charcoal. It was enough for aluminum but not enough for brass! I added just several pieces of coal. Coal gives much higher temperature than charcoal.
Thanks for your links graydog111. Both knifes look awesome. I like such things. I have several knifes and a sabre. Could be interesting to make something like you did myself. It's a pitty that I couldn't see the process of melting brass by oxy/acetylene torch. I've never seen how it works. You really did it in aluminum can and it didn't melt or burned through. Are you sure that it wasn't a steel can? First time I tried to melt down aluminum in a steel can and it burned through when aluminum started to melt: http://www.instructables.com/id/How-to-Make-a-Crucible/
You're welcome. Good luck.
Hi ToolboxGuy. Sand casting is also my purpose. I've just got some results in it, so will share them in a week or two. Please, follow my channel on youtube and here on Instructables. I've made a flask and green sand. Everything works good enough. Did you hear about some mixture of green sand where oil is used? I tried just mixture of sand and clay. In my opinion, that's more than enough to get a good mold.

Thanks again for your kind words Hank. :) I can only say the same about USA. I started to be interested in melting and casting because of videos made mostly by craftsmen from your country.
Thanks Jobar007. Yep, I'll never cast brass in a steel can again :) I'll think about some mold types which can be used. Maybe steel, maybe some mixtures of fire clay, grog, graphite...
I see and I'm from Ukraine. In October-November it'll be much colder. Of course not as cold as, for instnce in Alaska or Canada but much colder than in Florida :) How guys in Game of Thrones say: "Winter is coming". :)
Thanks. Completely agree. Of course I try to do everything safely. I don't use jeans and leather boots because of hot summer. Now it's September but still +27 C (80 F). It'll be colder soon, so I can use some protection :)
Brass casting - got nice ingotView Instructable »
Thank you Chewy0712. I've heared that extinguishers work fine as crucibles. My more complex crucible survived after 4 or 5 melting for now. So, it's also not bad. I'll post my experience today where I melt brass and my crucible is white, so it withstanded approximately 1200 C or 2192 F. I think not bad. Also I have a piece of stainless steel pipe with enough thick walls. It has bigger diameter and it's melting point should be higher than simple carbon steel. May be will try it as well in the future.
Thank you very much bill z. Yes, you're right about graphite. I understand that it's better to use graphite crucible! I'll try it in the future. I had a problem because the temperature wasn't enough that's 100%. I didn't get 2000 F. I've just made a new casting, so crucible was white (so that's approx. 2000 F) and brass was totally melted. I'll upload my new results on instructables this week.

Flask Making For Sand Casting Aluminum & Other Metals
Ok. That's right. I also have a lot of aluminum scrap as well as brass and copper. I tried to melt brass just after aluminum. I was curious If it would be much harder. The next I'll try is some mold casting.
Thanks for your comment BeachsideHank. Yep. I agree that steel is not the best solution. I've bought some fire clay, so will definitely make experiments in the future. Is this your article on the link? If yes what proportion of fire clay do you use in fire clay crucible? I've seen in youtube that one man used 40 % of fire clay and 60 % of grog powder. I haven't seen silicon carbide in supermarkets and fire clay is much easier to get. Also graphite dust (powder) is available, so I'll try everything that I can.

Hi. My short article is about crucibles, not "crubicle". I'd like to recommend you to look for specific metallurgical vocabulary in google or other open sources. If to be short it's a thing in which people melting metals.

You're welcome and thanks for your comment Seamster. :) If you're interested in this topic, you definitely should try someday. I've made this experiment one week ago. I had no practical experience in melting, except melting lead at home long time ago. In the nearest future I'll try to cast something into a mold using green sand I think. So, good luck if you decide to try yourself in melting and casting.
Thanks for your comment MandalorianMaker. I'm not sure about the quality of the coal. I took it in my woodshed. My grandparents had some greenhouses long time ago and used firewood and coal for heating. As I understand quality and coal grade depends on the region and depth where it was mining. Definitely, this one is not the best for melting purposes. Thanks for the advice. Now even charcoal in fact is enough for me but may be in the future I'll try some other coal if not decide to use propane! :)
