| here's a quick one for you. been in planning for a while.|
silica 74%, soda 21%, calcium oxide 5%
- The science and archaeology of materials (2000) promises this has a eutectic of 725°c. heh.
mixed well, piled in a dish. heat
| 800°c - it kinda began to pull together. |
it was a little solid, but when i poked it, it was 'soft'
| 1000°c - same as 800°c. but hotter. |
i maxed out my kiln at 1067°c and didn't wanna run it all night. turned off kiln.
| this morning it is a hard solid mass. plan to break it up and just give it more heat work. start a 2nd batch.|
