[@banzzz6337]

this video was amazing and very welly done. Im glad you showed the steps so well that some of it was so specific. it helped out so much i really appreciate it.

[@scottlund4562]

Yes! I had not seen anyone do prep to their crucible and wondered if and how it should be done. Thank You Again! PS. Love the Ebay store items

[@scottlund4562]

May I ask if this should be done to large, I believe ceramic, crucibles before going into the foundry furnace? I was left Dad's green-sand table, foundry, and equipment, and of course will take a class so to speak before using it, but your teachings have inspired me to quit being gun shy and go for it. (40 years ago as an 9 year old kid I "independently took Dad's torch to a piece of quartz in a vice...still have the scar from where the unroasted silicate popped and melted into my forearm)

[@sreetips]

Glazing a fuse silica melt dish, like the one in this video, is madatory. But I don't know about ceramic or clay crucibles in a large foundry. I do know that borax should be kept away from graphite crucibles at all costs.

[@scottlund4562]

sreetips Borax away from graphite? I would have never ever thought that and had it in mind to use it as a flux when I got it going. Glad you told me, thanks!

I watched other videos and you are the only one that glazes the bowl. I watched your video like 10 times and today, my new bowl turned out Great, not as good as yours but practice makes perfect right? Anywho... I just wanted to say thank you for the lesson and your time making this video. Have a great day!

[@sreetips]

Great, I'm glad that it helped you.

[@stevenedwards4470]

That was very thorough. I appreciate seeing it in detail. I'm about to do this for the first time. How does one judge how much borax to put in the melt itself? Like for a chunky silver ring and enough for the spur?

[@TheReal_TaylorSwift]

If you've used too much borax and it flows with the molten metal, how do you get remove the excess of the metal? You mentioned using sulfuric acid in another video. Is there anything else that could be used?

[@sreetips]

100ml distilled hot water with 5ml sulfuric acid.

[@michellet8654]

Awesome, this is much better than using Handy Flux, the end result of that is a dark grayish dish. The Borax leaves the dish still looking new!!!

[@maktheturd6220]

Hi! What's the difference between the 20 mule borax and borax use as a flux? And can you use the mule borax as a flux?

[@sreetips]

I only use Twenty Mule Team Borax from the grocery store.

[@wesleymccravy901]

I use my outdoor weed burner to heat the crucible when glazing. Definitely get hot enough with just propane… if your btu output is high enough. I do work it in though with MAPP gas afterward

[@onetwotwo9848]

Thanks, kad. Used an oxy/ace torch and bare hands-gets hot getting that close but turned out like yours... perfect first time trying it.

[@sreetips]

Bravo

[@thebhut3446]

Ive tried copying what you are doing, but my borax gets really bubbly blows around and wants to clump into balls that run down to the bottom of the dish leaving gaps, Ive had to go back with a graphite rod and spread it around to get the results you have. Any advice on what I might be doing wrong?

[@sreetips]

Use a map gas torch

[@dbaider9467]

I'm a noobie. This was helpful. I've had crucibles suddenly disintegrate on their own when not used - you reach for it and it's cracked and fragile. I think from damp. I fluxed the outside of the crucible also and this seems to help with damp migration. I think.

[@StygianBlood]

a year later yes but if it's still relevant try storing them with desiccant...a 5lb container of reusable stuff is on Amazon for like 30$

[@timellis9293]

Thank you, i did one bowl from watching another video and I have sticky spots in it so I did not try to melt my silver, I have 4 more to do and will be buying some borax tomorrow. The other video said to use flux. It looked nothing like yours when finished. I have black lines and tacky spots all in the bowl.

[@MartinJulia7]

Can i use kiln instead of torch and I will use handy flux

[@sreetips]

Not sure, I’ve never tried it.

[@anabelorozco3973]

I'm a newbie I tried using Propane didn't work saw ur video I'm gonna try it but question my torch is for Propane do I need new torch?

Get a map gas torch with auto-igniter. They used to be about fifty bucks, before they printed all these dollars and made them worthless.

Would a paint stripper gun be hot enough

[@sreetips]

I don’t think so

[@vidkapwin2586]

Wow, it added to my knowledge in melting gold. Does the boxas was really used as glazing for pottery business?

[@sreetips]

No, pottery glaze is different from borax.

[@scooterboyplays4419]

Thanks. I did exactly that but noticed on the reviews of the kit I purchased, a few questioned if the material was even a type of borax

[@sreetips]

I buy 20-mule-team borax from the hardware store. It's about $5 for a pound and it will last me several years.

[@scooterboyplays4419]

Thank you. Should I toss this new crucible and purchase another one? It has "borax" that is chipping and flaking off taking a little of the crucible with it. I am also concerned the temp in the air is working against me. It's an unheated garage, almost freezing. The propane torch has major difficulties. Should I run two torches or try acetolyne?

[@sreetips]

Propane, in my experience, does not get hot enough. I use MAP gas in a yellow cylinder. MAP gas will get much hotter and do the job nicely.

[@scooterboyplays4419]

That is the other option I was looking at. Would mapp gas get hot enough in a freezing environment if I build a tiny fire brick enclosure around the crucible?

[@sreetips]

That should not matter.

[@enricotrombini3671]

the smelter that I use puts borax in graphite crucibles by the hands full and don`t seem to be a problem?

[@sreetips]

The only graphite I use is the ingot mold. If borax gets anywhere near it when pouring a gold or silver bar, the borax will glue the freshly poured ingot in the mold. I've had to break graphite molds to get the ingots out because of the molten borax pouring over with the metal.I suppose a crucible made of graphite may be a different story.

[@kerryvix1582]

Is it necessary , or beneficial to add borax to a graphite crucible before using ?

You can use regular borax for cleaning right?

Could you do a video on how to clean out a crucible once its full of dirty borax? I've heard of some people using nitric acid to clean it, and others use soda ash. I just tried some soda ash and it seems to be dissolving the borax, leaving a white background, but I'm not sure if that's the crucible material I'm seeing or if that's residue from the soda ash.

Map is about 150 degrees F hotter than propane. I have seen dual propane torches inside an insulated enclosure work for melting small amounts of gold and silver

Do we have to do this each melt? Or will this one glazing be enough to last for a couple melts?

One glaze should last for multiple melts.

Great video thanks...I purchased a graphite 1 oz mold ... should that mold be glazed too? Or does that really matter in the quantity of the surface of the bar?

[@scooterboyplays4419]

I attempted to glaze my crucible but no matter what, it would pool up. I attempted to melt down a silver dime for a test run and the borax glaze would slowly engulf the dime. What should I do? Buy new crucible? Attempt to slowly grind it out?

[@sreetips]

Notice that I heat the dish to redness BEFORE I add the small pinch of borax. That way the borax sticks to the hot part of the dish. Then I use the flame to spread the molten borax evenly. I do this sides first and save the bottom for last.

[@shawnnewberry7058]

Hey Sreetips. Love your videos. I just finished my first gold button after watching your stuff and it's awesome. I was wondering if you know how to get copper out of my silver powder. I think I had too much nitric in the solution when I added the copper to precipitate and now it's red silver. Any ideas? Thanks again for the videos.

[@sreetips]

I get that my self from time to time. You're right, probably too much nitric. When dissolving your sterling/925 silver always make sure that there is still a little undissolved silver left over in the vessel when your reaction is done. If you have undissolved silver, and if you've got the solution hot, and if there are no more fumes being produced, then these are all good signs that most of the free nitric acid has been consumed by the reaction. If these conditions exist then you should be able to cement the silver on clean copper and not have to worry about excessive nitric consuming your copper and redissolving your cement silver as fast as it cements out. The cement silver will be about 995 pure. Also, I've added sulfamic acid until foaming ceases to kill excess nitric with some success. But make sure the container is inside another catch container in case it boils over on you.

[@shawnnewberry7058]

Thanks. I was thinking I'd make this red silver into shot and then put it back through the process, making sure I use up the nitric this time. Anyway, good stuff. Keep it going, we're all learning a lot.

[@OwlTech333]

I think this is happening with too concentrated solutions

[@endeeray4295]

So I guessing the red in my filter paper is red silver? I tried recovering with some scrap silver and I think I used too much 70% nitric acid. I still got plenty of silver precip but it is super fine. The rxn was pretty "lively" no overflow though! Seemed to take forever adding copper to use up the nitric. Didnt know what else to do with that. I also reclaimed the copper solution using sodium bicarb. Have lovely turquoise precip of copper carbonate but still have light blue fluid that does not respond to additional bicarb. Is that still copper? Sorry for all the long questions.

[@JB-sw5yc]

Great video! Question, though: When I tried doing this, the little pinches of borax I applied would just blow away when I brought the map gas to it. I brought each part of the crucible I was applying the borax to to a dull red just like you did, but it still blew away. How to I avoid that?

[@sreetips]

I don't know, it must be your technique.

[@alida1941]

Wouldn't this be because you didn't pre-heat the crucible? A hot crucible give the borax something to stick to.

sreetips thank you very much for the answer.... thank you for the huge effort and time you put into all your videos. I do have one other question, I wish I could include a pic but the dish I’m trying to glaze did not come out anything like yours. I have the same torch head and gas but the borax is spotty I guess is best description and the black spots are everywhere?? Not enough heat maybe? I have re-watched your video a couple times the only thing I think I maybe doing wrong is not holding the torch close enough ,then again maybe I am... I just don’t know...

[@sreetips]

The black spots are normal. I get them too. I think it is carbon that mingles with the molten borax. To get then to disappear just continue to heat the black spots until they go away. But be careful, you can scorch the dish if you get it too hot. Keep the flame moving.

[@1000rr2008cbr]

I have zero experience melting gold in a graphite crucible. I melt gold in a fuse silica open-face melt dish like the one in this video. I pour molten gold into a graphite mold. If even a tiny bit of molten borax gets into the graphite mold then it will glue the ingot into the mold. I've actually had to break molds to get the gold ingot out because of this. For this reason I recommend that borax be kept away from a graphite mold. Using borax in a graphite crucible may be a different story.

[@Ch4grin]

The adiabatic temperature of your MAP [sic] gas, which is actually propylene gas, is only marginally better than propane (3730F vs 3600F). I've read that the inner flame temperature of propylene is hotter than propane, but from the looks of your torch tip you're not taking advantage of that; you seem to be using an old MAPP torch and you're getting a wide/wobbly flame due to that. It's been ten years since real MAPP gas was available in the United States.

[@Rangiroasis]

Even a new Mapp torch has the same Turbo circular fat flame. Its design is fat to heat copper plumbing fittings, keeping a large area hot enough to draw 95/5 solder into the fitting and keep the opposite side of the fitting from cooling. It might not be the proper tip needed but its age has nothing to do with the flame produced.

[@MechInvent]

I'm so glad at least a few people know this. The og mapp factory blew up.

No, after the initial glaze it can be used over and over. For gold melting, I use the same dish many times. But I only melt pure gold in it. After cooling down, I put it up so I can use it again. After several melts tiny gold balls will cling to the side and not flow down to the bottom. When this happens I add a pinch of fresh powdered borax and the gold balls release and flow to the bottom. I'll probably use it 20 or 30 times until it begins to show signs of pitting, then I retire it to melting karat gold and glaze a new dish.

how long do you wait until you can melt?

[@sreetips]

Once treated with borax, the dish can be used to melt metal immediately.

Thanks so much

Great information thx…!

I've noticed several dozen very tiny gold beads stuck in the glazing in my melt dish. Any recommendation on getting them out. I've tried using a larger bead to collect them when melting but they won't budge. Any ideas would be much appreciated.

[@sreetips]

Yes, get the dish hot, then add a spoon full of borax. Then use the flame to rinse the beads down into the dish. If the sides of the dish are in good shape then the borax will melt and cause the gold beads to flow (flux means flow) down to the bottom of the dish. Then use the flame to manipulate the beads into a single bead and pluck it out before the molten borax hardens. Or, pour everything, molten borax and gold beads into a METAL container of tap water. Then use hot water to dissolve the borax glass and recover your gold beads.

did you mean a table spoon? a few of your pinches looked like half teaspoon alone.. great video just wanna make sure i dont overload the borax on my first pour!

[@sreetips]

No, I meant teaspoon. I use just enough to lightly coat the dish with borax. Too much borax will cause molten borax to pour with the molten metal. The excess borax will adhere to the ingot. Then it must be removed with a 5% solution of sulfuric acid (5ml concentrated sulfuric acid in about 100ml water) with some heat.

thank you

Don't they sell glazed crucibles? ..

[@sreetips]

Not that I know of.

[@zemetrius]

if they did, could you really be sure it was done right, or that enough (or maybe too much) borax was used. doing it yourself seems the best way to be sure it was done right, this video will keep me from making beginner mistakes.
