I have started making my own glazes. I found a great recipe called St. John’s black.
Nepheline Syenite – 25
Alberta Slip/Albany – 75
Cobalt Carbonate – 5%
But I wanted something more dense, so I tried working on the recipe by adding other materials.
Going from left to right I added:
5% – Black Iron Oxide – The first one ended up matte
5% – Manganese Carbonate – I like this one best. It has a sort of oil spot quality.
5% – Talc – This ended warm in tone. Not quite as glossy, and less oil spotty.
1.6%, 1.6%, 1.6% – Black Iron Oxide, Manganese Carbonate, Talc – Was an attempt to get the best of all of them. In truth though I think the Manganese Carbonate had the most interesting results.
