Hi Phil,

 

I am trying to understand your notes that you just posted about the photograph of your notebook. Here is what I think they say, and I have a couple of questions.

 

You have these 4 inch square tiles and you want to apply Gordon's glaze at a loading of .5 grams of dry glaze per square inch. You mixed a large batch of Gordon's glaze and you add 51 grams of H2O for every 100 grams of glaze, so that when you calculate the amount of dry glaze that should go on a tile, the calculation is 16 x .5 x 1.51 = 12.1 grams of glaze per tile.

 

You also mixed two batches of glaze, one with 4% Rutile (G1), and the other with 0% Rutile (G2), and at the end you mixed those together to arrive at a glaze with 2% Rutile (G1/2). In G1 you added a total of 11 grams of colorants, and in G2 you added 7 grams of colorant.

 

1) Did you add the water after you added the colorants?

 

If so, I have no other questions. But it appears that you did not.

 

2) Did you add 5.5 grams of water to G1 and 3.5 grams of water to G2 when you added the colorants so that your calculations would remain rigorous?

You're pretty handy.

 

Is this really iridescent like it seems?

This one does look great.
