The mineral corundum, with a Mohs hardness of 9, will be harder than a ceramic streak plate and therefore leave no streak.
THE EIGHT WAYS TO I.D. A MINERALThe eight ways to identify a mineral such as corundum are 1 hardness 2 crystal shape 3 special features 4 density 5 streak 6 luster 7 cleavage or fracture 8 color. (to find out hardness look up "Mohs scale of hardness" everything else you could search it on google or bing)
Diamond will not leave a streak on a porcelain streak plate because diamond is harder than the streak plate. It will leave a scratch on the streak plate for the same reason.
The streak of a mineral refers to the color left on a streak plate after rubbing a mineral across its surface. A streak plate can be as simple as the unglazed side of a porcelain tile. The streak is the mineral in a powdered form from abrasion with the hard, slightly textured surface of the unglazed porcelain streak plate. The streak color may differ from the color observed in a specimen. The streak is used as an aid in the identification of minerals.
Streak is a method used to help identify minerals. A mineral can have very similar characteristics such as luster, colour, hardness, specific gravity ect, but even minerals with very similar characteristics including colour can have different streaks...which is the 'colour' the mineral makes on a scratch plate when drawn accross it in a stroke..thus creating the streak.
Streak and Mohs hardness are descriptive and identifying terms for minerals. Because sandstone could be composed of a multitude of different rock particles or minerals, a specific hardness or streak cannot be attributed to them.
Corundum is a mineral, therefore it could not be the hardest rock.
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.

You could give it the streak test, find its density, determine its melting point, check it for relative hardness, take it to a jeweler or geologist, or to a mineral assay office.
"Angery streak" is not a recognized term. It may be a misspelling or a misunderstanding of "angry streak," which could refer to a period of time when someone consistently displays anger or irritability in their behavior.
It depends, if there is no growth or colony appearance on streak line and only it shows growth in b/w the streak line then it is certainly a contamination and if there are colonies on streak line and not ressemble with the streak culture then also it is a contamination but there can be a chance that colony appears due to some fault in streaking procedure and the inoculum drops between the streak line so it depends.
You could use the streak color, whether it has cleavage or fracture, the texture, the luster, the hardness, the color, and lots of different properties.

No Undertaker's streak did not end (sadly i wanted hbk to end it). If you watch the latest wrestlemania wich is wrestlemania 27 Triple H could not end the 19-0 streak(sadly).
