Good you posted the engineered stone or quartz.I remembered some of the machine designers used quartz for greater strength and density.Good granite is 66% quartz.It appears quartz is better.Lets name itE/Q.This is defenatley worth researching.I think sand has high%quartz as it is left after the granite erodes away.
I searched a bit on the quartz engineered stone and found little.As Bruno said
the guy at the show would not reveal his source and I am having the same problem on the web.No apparent raw materials suppliers.One thing I found on the quartz countertops is they shake or vibrate and pull a vacuum at the same time.This is necessary as their ratios are 95%.Silica sand is probably a good starting point as it is mainly Quartz I beleive.As far as 1/4"to3/8" quartz aggregates I have no luck finding any.I ask the Zone boys to help in the search.Thanks

Larry,

I have found a good supplier of quartz sands and stones (unfortunately in Slovenia), so I will be doing some testing with it when I have the time. I have the epoxy and quartz already, just waiting for me to start experimenting.
I will post my results here once I have done something.
