Nelyrho 100 oz Troy Ounce Cast Iron Loaf Bar Ingot Mold Crucible with Handle for Melting Casting Refining Precious Metals Like Gold Silver Copper Aluminum Brass etc, Black

So far this has made about 150 ingots and still going strong. Great price for quality too.

I use this for aluminum and copper ingots. It works well. As the description says, it is cast iron, not graphite so it is heavier, solid and can take a few whacks on the concrete to get the ingot out of the mold without breaking like graphite does.

Nice ingot mold, holds heat well for those long sessions. Accepts large ladel pours easily. Seems incredible durable, and worth the price tag.

They work perfect!

Made well

I am writing this review to provide clarity on the two different sizes. I purchased both and determined the capacity of each in milliliters. The "100 oz" holds approximately 375 mL (or 375 cm³) of distilled water at room temperature. That is full to the brim. The only metal with a density that will be near "100 oz" is 100 troy-ounces of .999 Silver (300 cm³). 300 cm³ provides 20% of spare volume to prevent overfilling the mold. On to the "50 oz" mold. The "50 oz" holds approximately 100 mL (or 100 cm³) of distilled water at room temperature. Again, that is full to the brim. The only metal with a density that will be near "50 oz" is 50 troy-ounces of .999 Gold (80 cm³). 80 cm³ provides 20% of spare volume to prevent overfilling the mold. This means that the "100 oz" mold is NOT twice the size of the "50 oz" mold. The "50 oz" mold is actually 26.7% of the size of the "100 oz" mold. Side-by-side, the "100 oz" mold dwarfs the "50 oz" mold. This means that the "100 oz" mold is approximately 3.75 times the size of the "50 oz" mold. At the end of the day, assuming the use metals of high-purity (99.9%+ pure), here is how much you should be able to fit in each mold filled safely to approximately 80%. (Metal / 100 oz Mold / 50 oz Mold / Unit of Measure) Gold / 186.3 / 49.7 / oz-t Silver / 101.2 / 27.0 / oz-t Copper / 94.6 / 25.2 / oz-avdp Aluminum / 28.7 / 7.6 / oz-avdp oz-t = troy ounce = 1/12th of a pound = 31.1035 grams oz-avdp = avoirdupois ounce = 1/16th of a pound = 28.3495 grams "avoirdupois ounce" = what is commonly just called an "ounce" in the United States As for the molds themselves, I will contradict some other reviews and rate them 5-stars. As long as you preheat the molds to 350-450°F (175-230°C) then allow the metal to freeze and cool to the point that there are no signs of glowing from the ingot or the mold before trying to remove the ingots, you should not encounter the issues others are citing.

edit: the edges are the first one I ordered weren't super straight so they sent me another one. this one's a lot better

Very well built, unfortunately too big for my use.

Excelente

Looks good. Well made.

使用前だが、本品は肉厚・重量・鋳鉄の品質ともに問題なさそうです。本品に適する溶解金属は、低融点の順に、鉛・アルミニウム・銅(・金)までと思います。

Arrived yesterday and used straight away just perfect

Worked well. Tougher than I expected. A1
