Pre-modern steels include:

1. Forge-carburised steel. Start with iron, heat in forge, in a high-carbon reducing atmosphere (i.e., put the iron in there, surrounded by charcoal, in a low-oxygen part of the forge), and carbon diffuses into the iron. If you want more than a thin layer on the outside (as done in case-hardening), cut the iron into thin narrow strips, and then weld them together after carburising (piled construction). The iron is typically wrought iron from a bloomery smelter. This was an early process, and a large-scale version was used in more modern times (the cementation process, which produces "blister steel").

2. Bloomery steel. If you are using a bloomery furnace to smelt your iron (i.e., convert your ore to metallic iron), you can make steel in the same process. This means using higher temperatures than needed to smelt the ore (in order to obtain faster diffusion of carbon into the iron), and those higher temperature are usually maintained for longer. Sometimes a forced blast is used to increase the temperature (by increasing the air supply for combustion); this isn't the continuously-fed, continuously tapped blast furnace used for making cast iron, but a blast-bloomery. It's possible to obtain steel with carbon contents of well over 1% by this method, but typical carbon content is lower. The carbon content of the bloom varies over the bloom, so the product is usually partly wrought iron, partly low carbon steel, and partly high carbon steel (and sometimes some cast iron, where part of the bloom melts if the carbon content becomes too high (which reduces the melting point). Bloomery steel was the usual steel used in Europe until decarburisation of cast iron in the finery forge and puddling replaced it from the 15th to the 18th centuries (depending on where), and was used in Japan, SE Asia, and Africa until modern industrial steelmaking was introducted.

3. Crucible steel. Mix wrought iron and a carbon source (sometimes plant material, sometimes charcoal, and often cast iron) in a closed crucible and heat. This was a common process in Central Asia and India, and appears to have been used in East Asia (Korea and China). The product is typically an ultra-high carbon steel, often 1.5-2% carbon.

4. Decarburised cast iron. This was first introduced in China, and became the dominant steelmaking method in China during the Han Dynasty. For decarburisation, the cast iron is heated in an oxidising atmosphere. This can be done in either the solid state (preferably with the cast iron broken into small pieces) or the liquid state (e.g., puddling). For decarburising in the liquid state, the increase in the melting point of the alloy as the carbon content drops can be used to remove the steel. This is, more or less, the modern process of steelmaking.

5. Forge-welded steel. Wrought iron or low carbon steel can be stacked together with pieces of cast iron, and welded together. This material then needs to be folded repeatedly (flatten, fold, forge-weld, and repeat) until sufficiently homogeneous. This is suitable for small-scale production. It's best known for being used on occasion in Japanese sword-making (where it is still used today); the Japanese name for such steel is oroshigane (but the bulk of traditional Japanese steel used in sword-making is bloomery steel (tamahagane, which is high-carbon bloomery steel).

The modern crucible steel process (i.e., the 18th century Huntsman process - Huntsman is your clockmaker) shares heating in a closed crucible with the old Central Asian crucible steel process, but the raw material is blister steel. The old Central Asian process is a steel-making process, while the Huntsman process is a steel-refining process - the input material is an inhomogeneous steel with a high slag content, and the output is a low-slag homogeneous high-quality steel.

Crucible steel continued to be made and used in Central Asia and India until it was displaced by cheaper imported modern industrial steel.

So i know that- Wootz is the "original" consisting of wraught iron and cast iron melted together in a crucible and forged in such a way to preserve the patern within, and must be made from ore from certain regions due to mineral composition (india and syria are two i know of)

Crucible steel is similar, just without the pattern due to the ore not being having the neccesairy composition

Blister steel is made of thin(ish) pieces of iron that have been case hardened enough to be turned entirly into steel

And then a clockmaker in the 18th(?) Century melted blister steel in a crucible/airtight container to give it more uniformity in carbon content and grain structure, and is the closest to modern steel

So was crucible steel used (where the piece was to large to be made of/into blister steel) until modern steel replaced it, or was blister steel forge-welded into larger enough pieces? (I assume the answer will change depending on time and place, so whatever was most widly/most comminly used would be helpfull)
