Customer Reviews for VEVOR High Purity Graphite Crucible, 2 kg Graphite Furnace, Double Ring Graphite Crucible for Melting Metal Gold Silver Copper Aluminum, Smelting Furnace Metal Graphite Jewelry Casting Tools

This is my first graphite crucible I've used and it seems to be pretty high quality, compared to a silicone carbide crucible that I have used before, only time will tell how long it holds up. I like how smooth the surface of this crucible is but not sure how long the smooth surface is supposed to last. It's very important to follow the direction about the initial first heating and cooling to prolong the life of your crucible

I bought a few of these Crucibles to melt various types of precious metals in so I wouldn't cross contaminate by using the same one over and over. They work great and seem to heat evenly, but must be handled with care. I accidentally dropped one into the Furnace too quickly and broke the lip completely off of it. Totally my fault, and I don't blame the craftsmanship of the product.

I get 10-15 firings when melting aluminum with this crucible, for copper i wouldn’t pass 6-7. 5-6 to be on the safe side so it won’t crack while pouring. Never fill it up all the way to the rim.fill 3/4 ideally. When new: Always heat upto 500c for 15-20 mins first time using and then increase to 900c empty for 15 mins or so. then let it cool inside the furnace overnight. Afterwards you can start melting metal and get more firings out of it. Do not bang or drop it. Always heat your prongs, clamps and any other tools that may come in contact with the hot crucible. Always heat your molds to prevent steam explosions. Use protective gloves, shoes, goggles etc….

Quick delivery! Accurate description. lowest price i found.

Opened the box and the crucible looked so good and shiny I kinda don't to use it because it's so nice looking.

I used 2 other crucible to melt a tiny piece of gold that I own and with the other 2 crucibles, the graphite ashed and the gold was not binding to make a solid nugget. I used flux in both crucibles and still the gold wouldn't bind because the crucibles were ashing. With this VEVOR vendor crucible, it bound immediately and poured in one solid piece. After the 1 one use at 1050°C the crucible is still smooth with little wear. I only used the other 2 crucibles a few times at less temperature. Nice crucible with VEVOR

Well made and it does exactly what I need

Perfect for my gold and silver smelting
