In Topic: Amorphous Silica Vs Just "silica" In Glaze?

07 July 2014 - 07:56 AM

You might want to check if your supplier lists flint or quartz. I've never bought

"silica" in the UK other than as flint or quartz.


Quoting from Digitalfire http://digitalfire.c.../flint_316.html

The terms flint, quartz and silica have come to be used interchangeably in

ceramics and you will see them all employed in recipes

Sounds like you're confusing a volume of 4 cubic-feet with an object that is a 4-foot cube.


For the record:

0.12m3 is the volume of a cube with sides of cuberoot(0.12) m ~ 0.49m.

4.12feet3 is the volume of a cube with sides of cuberoot(4.2) feet ~ 1.6feet.


Regards, Peter


Putting pi*0.26*0.26*0.55 into google gives the volume as  0.11680441486 [m3]

Putting pi*0.26*0.26*0.55 cubic meters in cubic feet into google gives 4.12490898 cubic feet

In Topic: Old Potters Wheel. I'm Fascinated!

>Is that the underside of a wheel seen behind him leaning against the wall? It kind of looks like the same circumference so maybe that is what the bottom looks like and might help in figuring all those questions out.


... and could the bottom pivot be standing in-front of the that wheel (like an upside down thumb-tack).


Could be a very nifty way of getting the centre of gravity of the wheel below a single pivot point,

and most of the mass at the circumference.
