Do you think this Melting Furnace will work for a few years? If I get a lot of Sterling Silver or maybe Gold I might get one.

I absolutely hate those cheap bits of crap.
They need a specialist carbon crucible that dissolves if you try to even use a little bit of flux and O2 from the air making it very likely it will dump its contents onto your toes without any warming.
The heating elements are completely exposed to all fumes and corrode at a startling rate.
Being so easy to plug in I have seen people using them in back bedrooms without ventilation or any adequate guards against fire.
I bought a small one when I first started, it lasted two or three melts and crapped out, when I sent it back the company simply denied ever hearing of me.
Build yourself a small gas powered furnace with quarts wool and refractory cement, it will cost you next to nothing build/operate and run for years.

I bought a Tabletop furnace and love it. I use it to pour my finished silver stock. The one I use is similar to the model you posted but made by a different company. I find though the crucibles are easily eaten up pretty quickly if I am running over long periods of time.

Some don't want the hassle of gas-powered rigs when they are doing it as a hobby. Not all tabletops are the same and maybe you got a bad unit. I have been using mine for about 6 years now and it hasn't had one issue besides the crucibles getting eaten up fairly quickly over long periods of use. But which is to be expected as this would be considered a consumable. If I took the time to research I am sure there would probably be a better crucible for the unit but. Had to break a process that has been working so well for me so far.

I have also seen the videos of people using these in their bedrooms and in areas they shouldn't be. When I watch those I think about saying something and know they will just come back with some dumb remark or say mind you business so I just let Darwin will take care of it.
 
jmd i have one of these, ive probably melted over 50 kilos of metal through it. Between silver and copper. It works great! It helps if you force air into the inlet with a shop vac, i can melt a kilo of silver in about 15 minutes.

Is this the Table Top furnace your talking about or one like it? https://www.ebay.com/itm/382082324192?hash=item58f5e196e0:g:eek:XkAAOSwEVdfqqTh

How much Silver will it melt?

Nope this would be the one I was talking about.

Let me know if you have any questions:)

I am glad I read this thread as I was on the fence regarding the oxygen-acetylene torch with some portable propane torches and melt dishes that I have seen Steve aka Kadriver aka streetips use or getting this ...

I am never going to need to melt more than 1 kg even with Silver and a big arse gas furnace is over-kill from where I am standing. Unless you are refining 6 days a week and at that point, I am going to ask you how you are getting that much scrap to process?
Although this product is advertised on Amazon.in it is not mickey-mouse / made in China like the ones I have seen for sale in the US on Amazon/Ebay and you can buy a crucible (same dimensions) from another supplier that will withstand a 25 megatonne nuclear war-head if this stock one shows signs of giving out on you.
India has one of the biggest steel industries on the planet with our domestic crude steel production expanded from 109.85 Million Tonnes Per Annum to 168.45 Million Tonnes Per Annum.
So there is a strong history of products that are industrial standard here. Plus they are not made in China as we still manufacture (wink).

I do agree that getting a mickey-mouse crucible made in China (supplied with your cheap-O bench unit on Ebay) that drops a 500 gm load of gold on your steel-toe work boots is going to induce some profanity that would make your mother give you the stink-eye.
But I would just say buy a legit crucible made out of high-quality materials to fit your furnace. Problem solved.

I think I will be avoiding running any gas here ... as why bother with the hassle of an oxygen-acetylene torch and or a big gas furnace when you do not need it. Streetips built one in his yard for peanuts but he needs YouTube content to keep up his subscription numbers (and their attention) and he needs to do those 2 kg silver smelting sessions (which he drops on the dirt).
Watch him do the poor at 9 min 27 ...
https://www.youtube.com/watch?v=urj9oCE2Y64&t=1s
Even I was holding my breath when he pulled the crucible out of the furnace with straight handled tongs ... I was thinking OMFG ... here we go!
But he did not drop it until he had the bar in situ ... extremely lucky indeed!
Having 2 kg of 961.8 °C smelted silver running around in your Italian loafers would have put a dent in your day.
But as Steve says in multiple videos "you are watching me learn here as I go!"

If you read this Steve ... you are the reason I gained the necessary motivation for getting involved in refining gold/silver. I would not be here without your efforts ... so nothing I say is intended in any form other than light heart jest.

My final point is that I would never be melting more than 200 gm of gold at a time and I doubt I will be melting any silver at all for a good while.
I will be inquarting my gold with silver but I will only recover it by cementing it out on copper and washing it.
Until the futures contracts (paper markets) stop instigating this insidious PM suppression I will just leave my silver cemented out in industrial size plastic drums inside polyurethane.
What burglar is going to give a bunch of cement coloured powder in a blue plastic industrial drum that is stored in your ladder next to multiple other drums with WPC80/MPC/whole-egg powder/maltodextrin powder etc in them a second look!?
And it is cheaper than buying more bloody safes that scream OPEN ME ... I CONTAIN VALUABLE ITEMS!

I am getting off-topic here ... but I know a very wealthy guy here in Gujarat who built a villa up in a nice spot in the hills (hill station) and he had the bricks for the fireplace made to the same shape as his 1 kg bullion bars and then got to painting the bullion bars with white-wash like the bricks he had made for the fireplace ... he then built them into the brick fireplace himself when completing the villa after the other tradesmen had left the job-site.
I can think of worse places to stash your casino chips (under the bed is so obvious).
And no he did not tell me where the villa he built was and I did not ask ...

This is not available thanks to the new world we all live in (the new normal) ... you will all be watching Streetips video on how to DIY your gas furnace soon.
Supply chains are crashing most places you look when the item is not essential/frequently used.
And as all these units on Ebay/Amazon.com that you buy in the US are made in China so you will be seeing more and more Not Available notifications as the weeks click by.
China has not been shipping these kinds of itmes to the US because they do want your $ and has not for over 5 years now. Both China and Russia have been dumping US treasuries' (since 2015) like they have the bubonic plague and buying ... drum roll ... gold and silver bullion while the LBMA and COMEX is kind enough to let them have it for mickey-mouse prices ... and the LBMA and COMEX is only doing this PM suppression to try and maintain the stability of their currencies (oh the irony)! Can anyone spell EXTREMELY SHORT TERM FIX?

In any case, the amount such a stupid electric furnace can melt is far better managed in a melting dish and a good quality cutting torch, or in actual fact even a bad torch would be better, Propane and Oxygen is cheaper to run than acetylene.
A small furnace should be at least capable of a few kilos of metal.

Every time I try to use my furnace for gold, Using a sand casting mold, this is what I get. It just doesn't get hot enough to liquefy the gold for a good pour. Silver, works great, but gold, not so great. That's 150.1 gram messed up gold "bar" that'll go into the forge.

How much are you melting?
Most of us just use torches.

Please ask where he lives, then post answer here.
