The Bloomery and wrought iron

What is the deal with wrought iron? If you have Tinkers Survival installed and remove the Tinkers recipes, we got a problem with the tech tree. To melt metals with Embers you need the melter, it is crafted using lead. Lead is mining level diamond, so you basically need an iron pickaxe to mine it. Easy, right? Wrong! Tinkers Survival disables the default tools so that you have to use the Tinkers Tools. But with Tinkers you create iron picks by melting iron and casting it. This works because the smeltery is only crafted with seared bricks, which are relatively easy to come by. But because the recipes got removed and the smeltery is therefore basically disabled, you need to use Embers melter to melt iron. Oh, wait, we needed the iron pick to craft the melter in the first place...

But have no fear, this is where wrought iron comes in. Wrought iron is gained by heating up iron together with a specific amount of carbon dioxide and is easily malleable. This is perfect to use as a material in the part builder (which of course doesn't get disabled). How do we get wrought iron? Put iron ore together with some charcoal in the bloomery and there you have it! Now you can craft an "iron" pick in the tool station. It is less durable but in all other traits basically the same! With this wrought iron pick you can now gather some lead and craft your desired melter to get your production up and running!
