I noticed that there seem to be no accurate guides on what laser drill foci do for our server so I ran a 3 hour test to see what picks up what and here are my results:
Blue: Mana Infused, Cobalt, Sapphire, N. Sapphire, Lapis, N. Lapis, Apatite
Red: Redstone, N. Redstone, Ruby, N. Ruby, Firestone
Yellow: Cheese, Sulfer, N. Sulfer, Gold, N. Gold, Yellorite, Glowstone
Green: Peridot, N. Peridot, N. Adamantium
Purple: Lead, N. Lead, Dark Iron, Tanzanite
Orange: Ardite, Amber, N. Amber, Copper, N. Copper
Magenta: Same as control
Pink: Same as control
Light Blue: Shiny, N. Platinum, Osmium, N. Osmium, Diamond, N. Diamond, N. Nikolite
Cyan: Certus, Malachite
Lime: Uranium, N. Uranium, Emerald, N. Emerald, N. Tennanite
Brown: Iron, N. Iron, Topaz
Black: Coal, N. Coal, N. Tungsten, N. Rutile
Grey: Steel, N. Pig Iron, Silver, N. Silver
Light Grey: Tin, N. Tin, Ferrous, N. Ferrous, N. Magnesium
White: Aluminum, Seltpeter, N. Saltpeter, N. Iridium, N. Salt
Control: Basically even amounts of everything but maybe a little more coal and iron.
For those confused, the control in a test like this is what the base line would be. It's the thing you are comparing the things you are testing to, which is in this case no foci.
