Today I was working on my piece for Influx Gallery's 'Fiat Lux' juried show and getting a matte finish was exactly what I needed for my piece. In fact I combined the matte finish with a 'sugar fire', the two enhance each other wonderfully. This is what I did...
- fire your first coat until fully fired and glossy
- sift on your second coat of enamel and fire until it just starts to melt (it is quite tricky to get the time right, if you take it out too soon the enamel will flake off, for our purposes it is better to go a little bit longer rather than underfire too much)
- the piece should look like its name - sugary but not orange peely
- you may want to practice on scrap metal first
- now submerge the piece in some Etchall glass etching liquid, usually takes 20 minutes or so, rinse well and dry
- any parts of the enamel that had gone past the sugar stage will now look beautifully matte
- of course you can use the Etchall on fully fired enamel too, to give a smooth matte finish
