The white stains you see on your bricks are likely efflorescence, which is salt and lime buildup. To remove efflorescence stains, simply brush them away with a stiff brush. For larger, more stubborn stains, scrub the stains with a water-detergent solution.

You should generally drill into the mortar joints when installing shutters on brick. Mortar is softer, which makes drilling easier and puts less strain on your tools. It also lowers the risk of cracking a brick—something that’s a lot harder to fix. Mortar holds fasteners well enough for standard shutters, and if you ever need to patch the holes later, it’s a much simpler job than dealing with damaged brick. Just keep in mind that if your mortar joints are too thin or the hardware calls for brick anchoring, you'll need to check the manufacturer’s recommendations and adjust accordingly.

Use fire bricks for a brick pizza oven. These bricks are typically used for fireplaces and chimneys as they can withstand high temperatures from heat sources. If you attempt to use any other kind of bricks, it’s likely that this material will crack from such high heat exposure in the best case—and potentially explode and cause serious harm in the worst case.

Yes, but used or reclaimed bricks can be more brittle, cracked, or uneven than new bricks, so they’re harder to cut cleanly by hand. For that reason, you should take extra care when scoring and striking, and expect a higher chance of breakage. If a brick feels especially fragile, score deeper before attempting to split it.
