Introduction: Stone Age Beer Mug

Picture of Stone Age Beer Mug

This is a must have custom stein

Step 1: Pick Out the Rock

This is the critical part. Pick a rock that is flat on one side(bottom) and the rest is just your own personal taste. I like this one because of the potential for a handle.

Step 2: Sculpting the Boulder

Picture of Sculpting the Boulder

Big hammer drill
3-9/16" core bit
1" drill bit
One inch chisel
Vegetable oil

As you can tell, this was all hilti. Drill, chisel, repeat. That is the hole.
I wanted a handle hole. So I laid it on its side and made one and a half holes. Yes, I broke the handle off trying to be cute. Nothing a little gorilla glue can't fix

Step 3: Gluing the Handle Together

Putting the handle back on.
If you have never used gorilla glue before, then, I will testify for it. I have fixed a lot of stuff with it. And now I can add granite to the list. Just remember it swells. Use clamps in every direction or it will make a huge mess.

Step 4: Cleaning and Oiling

I don't have any pics for this part. I washed it first with trisodiumphosphate. Then soaked it in dish washing soap. Then rinsed with water
After all the cleaning I massaged in a granite sealer. Last rubbed with vegetable oil. And rinsed clean.

Step 5: First Beer

I really expected to pour this half down my shirt. But by accident got a really good rim on one side. I don't know if I drank it fast because it was a hot august day or I had a twenty pound rock above my head. Either way it turned out pretty good.

Step 6: Voiala

I think Fred Flintstone would give an approval on this.

Suggestion: vegetable oils, any type, will become rancid over time. Ever get a whiff of that? Not nice and very difficult to remove. Use unscented mineral oil, generic is very cheap and has many other uses in kitchen. Salad bowls, cutting boards, etc. That expensive cutting board oil is mineral oil: odorless, colorless, tasteless.

Shantorian3d (author)ShamWerks2014-09-03

As a geologist I find this idea very coal, but about your beer choice we need to talc.

jwhitehouse (author)2014-09-04

cindysp8 (author)2014-09-01

Your uncle bob wants to know is it dishwasher safe

dalegribble (author)cindysp82014-09-01

for the mug, yes. For the dishwasher, no.

TSSJ-ryan (author)dalegribble2014-09-03

like button?

Eh Lie Us! (author)2014-09-03

What? Are you some sort of cave man? When I first saw the thumbnail I thought it was a rock candle holder. Wow. Right on man. I've worked with gorilla glue plenty of times and would have NEVER considered using it on granite. Another wow.

nmamalos (author)2014-09-03

Mind your teeth! otherwise really original consept!

swizzle (author)2014-09-02

Like the idea but a word of warning, some rocks can be harmful and deadly depending on what they can leech into your drink. That should be remedied by your sealing job but would have to be repeated once in a while to keep it sealed. With proper ventilation and a angle grinder and a $9 cement blade you can make a flat bottom and even design the mug a little bit. Just be aware that the rock dust can also be very toxic. Proper safety equipment and lots of ventilation and well your at it, cut a few whiskey cubes out of the same rock. Throw them in the freezer and add them to your drink. they'll keep it cold and wont water it down. :)

dagaherz (author)2014-09-02

now you are going to pick another 11 stones, aren't you?

I wanna mean to get a complete set... Lol

What is the power for the drill? Not sure if my 650 watt Bosch is strong enough or will die after the first attempt.

(Before arriving, I thought it was to hold the can, not the liquid!!)

beer20 (author)2014-09-02

Talk about a twelve ounce curl and then some! :D Nice instructable, is there a way to polish the inside and cut/smooth the lip so a good deal is achievable?

discgolftrainnut (author)2014-09-02

Raitis (author)2014-08-30

MsSweetSatisfaction (author)2014-08-30

I think Fred Flinstone would see it and immediately run off with it. Then I don't think anyone would ever catch him... It looks really awesome, thanks for sharing!
