Planet Interstellar Cloud Quartz has a uniform white background, a fine texture, and lengthy veins of three different hues of grey. The same faint, light stuff that makes stars permeates the interstellar voids. Interstellar Cloud slabs offer surfaces with clearly defined shapes, reflecting ambient light and enhancing our sense of space thanks to their bright, expressive veining that is invisible. Scrape off the dried remains of food preparation blunt-edged instruments to remove the buildup. Make sure you are very gentle in scraping the surface.
