You've got to start somewhere.
Using Dave's Dolomite Matt with Rutile Glaze (DDMRG!) I added measured quantities of colour or oxide.
Each pot contained 100g of glaze mix (measured by eye not scales)
I knew I wanted to mix a blueish colour and a green for my 'landscape' work but also a purple/mauve for the mountains too.
I kept asking my peers questions about quantities and potential results... "Experiment!" they replied!
I was very organised with my labels and test tiles ready. I had the glaze room to myself and I thought, 'what's the worst that can happen?'
I left the tiles (glazed) with a little note for Geoff and look forward to seeing the results next week.
