Frits: Too Many Numbers And Too Little Info

Recommended Posts

I went there first. It helps for common frits like Ferro 3134, 3124, 3110, but not many others.... I'm still confused!!!

What I would love is a chart that breaks down firing range, type frit and matching COE.
(kind of like the following.)
I' m not asking for much..... ;)....Right?


A. Low fire frits............................COE
.,............................. Lo........Med......Hi
1. Boron.
2. Lo aluminum
3. Hi aluminum
4. Lo calcium

B. Med fire frits
1.
2.
3.
4.

C. Hi fire frits
1.
2.
3.
4.

D Specialty frits.

It would be great to have 3 examples of each category giving a range of COE from lo, med, and hi.


So if there is an OCD potter out there that has anything like this alreday made up, please share.

Otherwise, my OCD tendencies will force me to expend much energy, try to create order, and go against the second law of thermodynamics.....yuk.

You are thinking about frits from a marerials based approach,. And if ANY raw material is all about the chemistry... it is frits. That is why they were developed. To understand frits.... think of them as oxide suppliers. And then spend t ime understanding the glaze chemsitry behind what those frits were designed for.

 

Frit X is not a "low fire frit"..... it is a source of a large number of Z oxide relative to Y oxide with a trace of Q oxide, so that allows you to get the oxide balance in a glaze to the point you need to melt in this range or develop this color. And so on.

 

best,

Thank you John..........I'm still on the steep end of the learning curve.  By-the-way, how long is the learnig curve steep. On second thought....don't tell me.
