Where is the Alum sourced from, and here is the block made?

Made in China. It's a poor quality alum block. I threw it away and purchased an Osma alum block which is made in France.

does this help prevent shaving bumps from ingrown hair ???

Hello Anthony - Yes this is one of the main benefits of alum block. The astringent properties not only stop bleeding, but for many people will subdue the irritations that cause razor bumps/razor burn.

Is it recommended to use this product without an aftershave? If not, should this product be used and allowed to dry before the aftershave is applied?

It has no scent. So, if you want to smell good, use an after shave. If you dont, I suppose you could use it just fine by itself. This does not affect it's styptic abilities. However, there is plenty to be said about the benefits of using it with an aftershave, especially an alcohol based after shave. I highly suggest you use an aftershave with it, but you dont have to.I let it dry, and then apply a splash-on after shave. This helps remove any residue that some claim all alum blocs leave behind (though I have had no residue with this product).

Does anyone use this with witch hazel? How is the combination?

I use this product in combination with witch hazel with no ill effects. The alum stops bleeding from any nicks but can leave my face a bit dry. The witch hazel (I use Thayer's) contains aloe and restores moisture without any greasy buildup you often find with other products.
