Iron chromate line test

Recently I have been messing with lots of iron in search of a good ancient copper. While searching I found a new mineral, well, new to me. Iron chromate. A iron and chrome compound that people use to get a darker version of a tin chrome red type glaze. I couldn't leave his on the table unplayed with so I bought about 1 lb of it and started to play with the levels of iron chromate and tin in my base glaze recipe.

This is a line test of my base glaze recipe +

• 3% Tin + 0.1 % iron chromate (1)

• 3% Tin + 0.2 % iron chromate (2)

• 3% Tin + 0.4 % iron chromate (3)

• 5% Tin + 0.4 % iron chromate (4)

• 5% Tin + 0.5 % iron chromate (5)

The key for me was to find a glaze that melted well enough to be a type of purple while still retaining a deep purple when the glaze is applied well. Kind of like some type of ox blood but with my own twist. I am very tired of tin chrome glazes calling themselves red when in fact they are a type of purple/ dark pink. I figured instead of complaining I might as well fix the issue by developing and producing my own version I am happy with.

As always the full recipe and UMF to this experiment will be posted on my parteon for my followers.
