[Solved] Can't make bronze!

[CreeperVon 22]

I put 3 stacks of full sized copper and 4 pieces of cassiterite into a vessel. I put this along with 3 clay molds and fired it. When it was done, the molds have cooked but nothing had happened to the metal? Help?

Time for some math!

 

1 full size ore = 25 units.

3*64 full size copper = 4,800 units

4 full size cassiterite = 100 units

 

Total units put into vessel = 4,900

 

100/4900 = 2% tin

4,800/4900 = 98% copper

 

According to http://terrafirmacraft.com/wiki/Alloy

 

Bronze is 88-92% Copper and 8-12% Tin.

There is a max of 16 in a stack, am I right?

[Kittychanley 1,002]

Oh oops. I'm so used to thinking stack = 64. Alright, tweaking the math.

 

3*16 full size copper = 1,200 units

4 full size cassiterite = 100 units

 

Total units in vessel = 1,300

 

100/1,300 = 7.69%

1,200/1,300 = 92.3%

 

So you are still just barely out of range.

So I need more tin? Like 1 more piece?

[Kittychanley 1,002]

Let's do the math!

 

1,200 copper units stays the same.

5 full size cassiterite = 125 units

 

Total units in vessel = 1325

 

125/1325 = 9.4% tin

 

So yes, one more piece.

Thanks so much!
