李植使劲回忆穿越前看过的土法坩埚炼钢资料，又想起一个办法：把熟铁烧成铁水后，倒入铺了一层铁矿粉的坩埚中，可以促进炉渣的生成。龙腾小说ltxsba.com
使用这个办法，造出来的钢材果然又好了一些
总之，李植亲力亲为，反复试验后世他在论上看到的各种方法“土法”。这些土法试验后有的有用，有的没用。但即便是算上在没用方法上消耗的时间，也远远强于没有头绪自己摸索了。在一次次的试验中，坩埚钢的质量不断提升。
忙到十月下旬的时候，李植最终产出了质量明显优于苏钢的坩埚钢。用这种坩埚钢的弹簧，的击发率达到了九成二。虽然只提高了半成击发率，但这半成击发率，在万人的战场上也许就能提高一些命中率，多打死几个敌人。
李植让蔡怀水定期去更多石墨坩埚，开始批量生产这种坩埚钢。
李植在城南建起一个较大的坩埚炉，炉子里可以放置十个坩埚，每个坩埚装铁水十五斤，每个坩埚位置每天可以烧五次，这个坩埚炉每天可以生产坩埚钢七百五十斤，一个月可以生产坩埚钢二万余斤。虽然这种产量不能和后世的炼钢炉比较，但在明代来说已经很可观了。
毕竟这产出的是数一数二的高质量钢材。
李植把坩埚钢生产分为十二个工序，雇佣三十个工人分别操作这些工序。这些工人只知道自己所操作的步骤，不知道别人的工序使用的材料是什么。没有一个工人知道全部生产流程，让李植的坩埚炼钢技术不至于外泄。
算上人工、材料、燃料和坩埚成本，李植的坩埚钢成本在五分银子一斤。这样的成本水平，让这种优秀钢材的用途十分广泛，可以用来做刺刀，做工具钢，甚至可以用来做头盔和铠甲。
李植生产出来的坩埚钢，让李植的铁匠们十分惊讶。他们第一次知道，炉子里练出来的钢材可以这么好。用这坩埚钢炼出的钢材锻件，硬度和韧度都超过了苏钢。铁匠们用坩埚钢重新了镗的镗杆，让膛制管的速度又提高了不少。如今一个铁匠操作一台镗，大半天就能镗出一根管。
李植最后决定对外这种坩埚钢。
坩埚钢虽然质量好，但是和这个时代千锤百炼得到的百炼钢比较起来质量也差不多，胜在成本低产量高。这样的产，没有必要藏起来
主意打定，李植就把坩埚钢放到了肥皂的商铺，价一两五钱一斤。
明代并不禁止民间冶炼和钢铁，比如在广东潮州和惠州就有许多民间冶铁厂，一年生产出来的钢铁数量惊人。但是经营钢铁需要一些背景，做这个生意的都是官商。寻常百姓经营这个和官商们竞争的话，是会被官府刁难到破产的。
李植贵为天津西路分守参将，也算是官商一个了，就连天子都知道李植的能征善战，天津清军厅同知现在也不敢刁难李植。
李植派出家丁，把半斤的小钢锭送到京畿各个州县给铁匠们，让铁匠们了解这种坩埚钢的性能。李植让家丁们告诉铁匠们坩埚钢在天津城东的李家商铺，就坐在家里等生意上门了。如果一个月能出一万斤坩埚钢的话，李植就有一万数千两的利润。
李植忙完了坩埚钢的，发现农民们热火朝天地开始往范家庄里交地租了。
