Deletion of Black lava salt

Comment: I am finding book references sufficient to meet . For example, https://books.google.com/books?id=UVTNDgAAQBAJ&pg=PA177&dq=%22Black+lava+salt%22&hl=en&sa=X&ved=0ahUKEwja2relqpHVAhWq1IMKHU3hDFUQ6AEIJjAA#v=onepage&q=%22Black%20lava%20salt%22&f=false here at p. 177. And somewhat briefer, but similar https://books.google.com/books?id=1fpmAQAAQBAJ&pg=PT32&dq=%22Black+lava+salt%22&hl=en&sa=X&ved=0ahUKEwja2relqpHVAhWq1IMKHU3hDFUQ6AEIODAD#v=onepage&q=%22Black%20lava%20salt%22&f=false here. And https://books.google.com/books?id=oGaF5FZ-sMMC&pg=PA244&dq=%22Black+lava+salt%22&hl=en&sa=X&ved=0ahUKEwikwp-Aq5HVAhXC1IMKHb_PD8I4ChDoAQgoMAE#v=onepage&q=%22Black%20lava%20salt%22&f=false here at p. 244, a description contrasting this salt with other types. There are numerous cookbook references to recipes using this salt as an ingedient, as well

Comment: to Sea salt.  Does not merit its own article, it is hard to imagine this ever being more than a |dictionary definition
