<\/a><\/figure>\n\n\n\nSo first batch:<\/h3>\n\n\n\n- Mayco Foundations red on the front, foundations black on the back<\/li>
- S&C Blue Yonder front, Bellisssimo Limelicious on the back<\/li>
- Mayco Copper Metalic on the front, Mayco transparent crackle on the back. Not going to use the raku pot for this fire, I want to see what it does without.<\/li><\/ol>\n\n\n\n
Fired in an 800w microwave in a large kiln, 32 minutes, same as works reliably for Stroke and Coat.<\/p>\n\n\n\n![\"\"](\"http:\/\/www.fluster.co.uk\/wordpress\/wp-content\/uploads\/2022\/08\/20220806_111048-1024x305.jpg\")
<\/a>Fronts: Red, blue copper.<\/figcaption><\/figure>\n\n\n\nAt least the copper is consistent. This is what I saw in the other test fires after the raku combustion stage. So very different on different clays.<\/p>\n\n\n\n![\"\"](\"http:\/\/www.fluster.co.uk\/wordpress\/wp-content\/uploads\/2022\/08\/20220806_111132-1024x337.jpg\")
<\/a>Backs: Black, green, crackle.<\/figcaption><\/figure>\n\n\n\nWith the crackle, I dropped them into water when hot, but I’ll give it a couple of days for the cracks to develop before adding acrylic ink to highlight them.
Glad that the Foundations and Bellisssimo like to be fired the same as Stroke & Coat.<\/p>\n\n\n\n
More copper.<\/h2>\n\n\n\n
Ok, more copper tests.<\/p>\n\n\n\n
On white: 3 coats copper front, 2 on the back
On terracotta: 3 coats copper front, on back, 2 coats S&C yellow, 2 coats copper<\/p>\n\n\n\n
- ‘4’ tiles: 12 mins, no reduction.<\/li>
- ‘5’ tiles: 22 mins, reduced in tin with brown paper.<\/li><\/ul>\n\n\n\n

<\/a>2 different clays, 3 different firing times…<\/figcaption><\/figure>\n\n\n\nAaaarhhgggg. Still not working! The 22 and 32mins are quite similar. The ones that I reduced have a sort of metallic sheen, but no sign of copper!!!<\/p>\n\n\n\n
Going to throw a strop and stop for now.<\/p>\n\n\n\n
\n\n\n\nDays pass. Try again.<\/h2>\n\n\n\n
Ok, 2 more tilesets. <\/p>\n\n\n\n

<\/a>No bubbling!!! These are all definitely Metalic. No difference 1or 2 coats copper
