ninguna vs. nada

Question

in lesson 2.11 there is a sentence:

no uso nada de la tiza nunca - I never use chalk

if I wanted to use ninguna in this sentence (with ALMOST the same meaning, because I think there will be a slight change of it anyhow) should I say:

no uso ninguna tiza nunca ? or :

no uso ningunas tizas nunca ?

thx in advance

Answer 1

ningunas tizas is wrong

Answer 2

i checked on worldreference.com and they say that tiza can be both countable and uncountable, depending on the context

Answer 3

I take it that 'tiza' is an uncountable noun, like water or salt. You shouldn't use 'ninguno'. I have to admit that i'm guessing.
