I would do more clay but the real problem is having access to a kiln than the base ingredients/tools
thats the neatest part about it, you don't have to fire it. if you really just cannot live without it being water-stable you can coat it in plaster or something. if you don't mind a time limit and wearing gloves you can mix cement into it for more robust structure. there's also the option of mixing a fine plastic powder into the clay and baking it in a oven when done.
funny thing, you can make a kiln from clay too. its a very versatile material lol
the biggest trick to getting a good kiln geometry is to somehow slow down the flame i.e. by making it pass through a bunch of small holes. i think primitive technology on youtube has a few ok designs, nothing i'd say are particularly great though.
if you don't have a whole lot of ventilation available electric or hydrogen kilns are pretty reasonable to build too.
for electric kilns either silicon carbide or graphite electrodes work really well, both are made in a similar fashion. nichrome wire is a bit lacking imo, some people have had a good experience but for the most part it really just doesn't hold up for higher firing clays and isn't that durable otherwise. for kiln insulation i'd say carbon foam made from thermolysis of old memory foam mattresses is a pretty great option.
