Youre trying to use a living creature to make other living creatures from that. That's . . . not possible as such, though we can ensure that this is a material
and a mythical creature. You might be able to find workarounds or hacks to do whatever you initially intended, such as slimers bursting from razor queens or queens spawning slimers, or them being allied or what have you.
In the slimer creature, youve defined a material. Thats it. Technically the creature (that doesnt exist) isnt even made of goldsteel, it just houses the material definition that this creature would use for a hypothetical goldsteel, if it were made from it or could excrete it.
1: by making goldsteel an official material (making a new material file and classifying it as a rock, tiusse, or whatever. Look to the inorganic or tissue files) you can then safely add the material to any creature without the game treating the materials as separate or you having to redefine it from scratch every time.
1b: you could also just redefine the material in the razor queen raws, but then youd have to keep defining it for every source of it, and then you couldnt make ores of it or do anything else with it. But for a one-off material, it works. Kind of like defining a syndrome for a creature or making something super resilient.
2: Then you need to tell the game to use it as an organic part of a creature. The tissue templates are how you do this. Body_detail_plan is what youd set up, making a template that includes goldsteel, which you can the specify for the creature.
2b: conversely, you could set tissue layers for the creature as per usual, the replace the relevant parts with goldsteel. ie replace all skin with goldsteel.

^^ In here, the relevant part is how I modded out the skin and fat, and replaced it with wood. But I still had to make sure a material called 'wood' existed, and use a relevant tissue template. I used a mammalian template, and modded out the meat for wood.
