Help Me Identify These Bricks

02 November 2015 - 02:30 PM

I just got 188 of these fire bricks for $75.  They measure 4" x 4" x 11.5".   They were unused liner bricks for a steel foundry.  They have no name just  the following: " l5l17 ".  Each weighs 10.4 lbs.  


Has anyone seen this type of brick before? Some of the tongue and groove bricks I see on the internet are made to withstand cone 32?

What's The Best Way To Separate 200 Mesh Silica From Common Sand

07 September 2015 - 08:52 PM

I live on top of red sand dunes. They are just down the road. I want to use the red sand in a "local" glaze. What would be most effecient way to separate out the 200 mesh grains? I thought about
1. washing the sand through filter material to collect the smaller particles.
2. Aerosolize And collect the dust through a filter. (Not my first choice.)
3. ball mill the sand.
4. Your idea.



Cone Numbers- No Cone 0

21 August 2015 - 11:19 AM

I didn't sleep last night. Something was nagging at my mind. Then at 3:30 AM it came to me.....There in no cone 0. The chart goes from 01 to 1 in the blink of the eye. NO CONE 0. How many more nights will I turn in my bed wondering why "0" got neglected.

Then my mind drifted to the calender year progression and I noticed "it" happened again. The calender year jumped from 1 BC to 1 AD without a "0" year.

I spent the rest of the night racking my brain to find other examples where "0" had been ignored. I fear that may represent a whole month of sleepless nights of pondering the meaning of not having zero.

I think ceramics and time are conspiring together and refuse to give us "nothing."

If anyone else is wondering what happened to cone 0, enquiring minds want to know.


Moqui Balls For Rio

31 July 2015 - 05:47 PM

I went for walk this Am and picked up some moqui balls. They are made of hematite. Ground hematite is about 90% RIO. So I thought I'd throw them in the ball mill and make some locally grown RIO.

The pic is an example of what they look like. It's not my photo.... Too lazy to take a picture and upload it
