Two months in the making, our new production equipment has just been
delivered by the machine shop. So very soon we should be producing
thousands of our low cost earthenware candles monthly. These are
saturated with a tiny amount of silver, and kill 100% of the bacteria
that cause diarrheal illnesses, a grave problem in developing
countries. Have a look at the new link:

Bye for now.

Dear Ried,
Why not have a Slip-Casting method?
Or, better yet, if the shape is a simple 'thick' cylinder with a need for a
uniform 'top' diameter...why not have them 'thrown' on a wheel, with a
simple die or rough 'go - no go' gauge to keep the tops close, and then a
'final' simple screed or gauge to get the tops just right diameter-wise,
before they are fired, but have dried?
Why is there an injection molded plastic 'top'?
What does the 'top' do?
Does it keep out dust and whatever as may fall in?
Would a ceramic 'top' do?
All these Pressing dies and the press and all are very cool...
But I do not understand why that method is elected in favor of much more
simple and less costly means, a less cumbersome means, as would in their
way,
produce a sufficiently uniform product ?
Even a novice 'Potter' could make a few hundred a day on a simple
'Wheel'...where this Pressing method has a lot of moves to it...at your
count, one every five minutes is 12 an hour, is 96 in eight hours, is a lot
less than a novice Potter could 'do' with a whole lot less 'tech'...
And...how uniform must it be?
If they could have ceramic 'tops', would they have to be all that 'uniform'
from one-to-another?
Could the making of these on some simple Kick-Wheels or other, interest
local people into making Pottery other than these as well?
If these were made by local people ON 'wheels', that might catch on if some
of them began to have some aptitude at the task, and so on...which being
people I would expect some of them to excell at pretty quick.
There is allways someone who might walk by and realize it is in them TO do
these kind of things...
Anyway...Congratulations!
And...I am confused!

Dear Ried,

A Potter could easily make the 'small' ones, 'medium' ones and 'large' =
ones as well without additional and costly Tooling.
And...how uniform must it be?
If they could have ceramic 'tops', would they have to be all that =
'uniform'

There is allways someone who might walk by and realize it is in them TO =
do
these kind of things...who wouod feel the tug...feel the 'pull' !
Anyway...Congratulations!
And...I am confused!
Does the 'Pressing' method defer to some necessary final porosity or =
cintered-density of the body once fired, which would not be attained by =
other methods?
Or is the final porosity a function of the composition of the Clay Body' =
behavoir at the Temperature to which it is fired?
In other ways, must you do it this way?
