One of my big bugbears in jewelry making was wire ingots.
As if heating this big bar of pig iron up to temperature and then using a cigarette butt as stopper wasn't bad enough, trying to get the ingot out was often problematic.
Especially with white gold, which often has a tendency to 'solder' onto the iron.
I have been using the method described below for about 15 years ans I personally think its a vast improvement over the commercially available casting ingots.
I make it out of normal mild steel that is available at hardware stores.
The base is 200 mm long and 40 mm wide and 4 mm thick.
The rest is 8 mm square bar.
And 100 mm length of 5 mm rod that the lock pins are made of.
Then I tap all the holes in the square bar with a 4 mm tap.
Casting anything smaller than 5 mm square is not efficient because it becomes to finicky to pour and you spend more time fixing a bad cast than working.
Because I cast a known weight into a fixed cavity, it means that I always get a perfectly cast metal bar.
I have another ingot mold in this fashion that goes up to 10 mm square, but I so seldom use the large size. So, I only designed this ingot to be used for most of the general use in general metalsmithing.
Namely, 5 mm and 8 mm in the 20 to 30 gram range is basically what gets used the most in general small workshops.
