Found this in a box I had stored away with other rock stuff... I think its a type of dopping stuff you mix together. It's a powder.

I'm an old-timer and if I had the energy I could check through my old Lap Journals to find their ad. Lacking energy I'll have to use my memory. I think this stuff was used to aggregate a number of small agate nodules or whatever so they could be slabbed together. The nodules were placed in an empty milk carton or something similar and the liquid cement was poured into the carton. When set it was clamped into the saw vise and slabbed. I still use that method for slabbing tiny nodules or other materials I don't care about orienting for color, etc. I've used Plaster of Paris and don't like it -- I wish something similar to this Lapidabrade product was still available.

Lowes sandless tile grout(Mapei brand). Used for tile joints less than 1/8 inch. No sand, uses polymers for aggregate. Rio Grande pebbles done in sandless grout

I built a form later Charlie. That would make a block 6" tall and 9" wide(6" X 9" slabs) and 12" long to fit in the vice of an 18" saw. It was easy to pour and easy to slab. Waited 3 days for the grout to cure, no sooner. Then tumble them for a few days to get the grout off of them. I used 75% kerosene and 25% 10W-40 for saw oil, and at times regular Mobil saw oil. I think the portland cement is hard on the saw oil, but never noticed any ill effects. 1"-2" Rio Grande pebbles.

When I worked at Lapidabrade Inc in the early 1970s I used to pack up this product called Stik-Tite. It came in two parts, sodium silicate and powdered limestone. The limestone was used as a filler to make a thick paste and when mixed you could adhere a rock to a block of wood and after it had set-up you could clamp the wood in your saw vice and slice away. Water would dissolve it so if you used water as a coolent instead of oil you had to coat the stick-tite with grease or something else to waterproof it. All the best and keep on cuttin, Don
