To tumble glass with a cement mixer all you have to do is put the glass in with some play sand. Tilt it like you would to mix cement and turn it on...It takes a couple of hours to smooth out the edges. I have done it many times and love the results. This is how I did the glass that I used around stepping stones as mulch in my garden.

A member now passed on - FLAGTRUCK - had a small one from Harbor Freight - they were about $100 last time I checked. She used it to tumble plate shards. I suppose you could tumble glass, but I wouldn't think for very long at a time. Last time I tumbled glass was in an ice cream freezer, and 15/20 minutes was long enough. Excuse me, but disturbing neighbors wouldn't keep me from using it outside. My neighbors used to get the sound of my tile saw, which is much louder than a mixer.

premix, with chopsticks! put a glob on a paper, right in front of them and they can pick up little bits of the adhesive with the chopstick and put it on the back of each piece. it's a neat way to do it and several have already posted this idea in a few different ways of it... no tubes of the runny stuff and no need to have too much clean up later. the most they're going to have, is a bunch of it dried on their hands. I haven't figured out a way to eliminate that part yet.lol it comes in the little tubs I have mentioned before. sanded grout/adhesive all in one. I get them at Home Depot. my favorite is the antique white.it's an aged vintage look. then I always end up painting over it anyway..lol when I did the frying pan, I used it and then I painte it but I used a crackle paint, under the second coat and that's why the black shows through the second color. I wanted that aged, cracked look or was it a different color under the reddish? I can't remember..I painted it more than once..lol then I used the chopstick to clean off the dry grout from the pieces when it was all dry. remember that comment I made, way back when, about when I was in the court room and I was quietly nipping bits of the grout off of the pan and the judge asked me to leave, cuz of a 'contraband weapon' in the court room? hello, a chopstick??? (not me!..I was with a friend for a civil violation)

Wish my "uh oh" was that easy to fix. DH is off mowing pasture, so I took the Cub Cadet for a spin and mowed in the back yard for a few hours. I breathed a sigh of relief when the mower kept running after I ran over a big old stump, but then the blades quit a few minutes later. *sigh* I can hear the butt-chewing now......................
