Spent the weekend in Texas and decided to pick up a little rock. I would've liked to pick up more, but I ran out of room. This will take me awhile to heat treat anyway. It doesn't look like much in the pic, but there's 8 to 10 Turkey roaster batches there. Josh

Do you cook that whole or can/will you knock out bifaces before heating?

Not a bad haul. Where in TX ??

If that behaves like similar bull gravel I have heated here (probably from LaGrange, TX), there will be little of it fit for anything after cooking it whole. When I slice it into slabs, it can take more heat than my turkey roaster will put out, and a lot of it flakes beautifully.

Looks like it already has good color.

I really have no idea where it originated. It's landscaping rock that one of my customers in Houston lets me pick through. Most of this batch is about the size of large bifaces with little to no cortex remaining. Those I will cook whole. The bigger stuff will get spawled out first. The pink color is just the reflection off my red truck. There are a few rootbeer colored cobbles in the pile. But most of it is shades of tan and gray. Josh

is it rock the from landscaping at the business he works at, or does he supply landscaping material to the houston area?
just wondering because i work in houston.

Ok it has a color reflecting from the truck! There goes my it is "magical Texas Tower rock" you know the kind that allows for super super thin amazing points. :) :)

Heat it up. It works great. It's probably dredged from the Brazos, Colorado,or Trinity river. That rock can have the most amazing colors when heated. I usually spall & biface before I heat it up. Great haul!!

I like that rock. Looks like my pile.
The rootbeer colored ones are my favorite and what I look for mostly.
goodluck with it.

I managed to get about 20 lbs. heat treated over the weekend. I only treated the smaller stuff that was no more than a couple inches thick. I didn't do any bifacing or spalling and it came out pretty good. The bigger stuff will get spalled out before I try it. I slowly ramped up to 400 in 50 degree increments over a 12 hr period and then let it soak for 15 hrs. I then brought it back down the same way that I brought it up. I even got gutsy enough to heat treat a little of the coral Eddie sent me a couple yrs ago. That came out real nice as well. I'm probably going to have a little time to knap today since the Kenebago crapped out on me again. >:( Josh
