This week we fired the clay pots we made in Week 3. My group, Group E, fired our pots together with Group F. We measured the data for three pots: Hope’s pot, Elek’s pot, and Gisele’s pot – in other words, one from each group (Hope’s and Elek’s from E and F, respectively) and one (Gisele’s) made with arb clay instead of store-bought clay.
After getting the fire started, we checked the temperature roughly every 5 minutes.
| Time after fire started (minutes) | Temperature of fire (℃) |
| 5 | 123.4 ℃ |
| 10 | 224.5 ℃ |
| 15 | 339.9 ℃ |
| 20 | 197.9 ℃ |
| 25 | 271.1 ℃ |
| 30 | 330.3 ℃ |
| 35 | 507.2 ℃ |
| 40 | 493.8 ℃ |
| 45 | 590.3 ℃ |
| 50 | 422.6 ℃ |
| 55 | 647.7 ℃ |
Below is the data for the individual clay pots that we measured. Once again, we measured in intervals of 5 minutes, starting at the 20 minute mark for Elek and Gisele’s pots, and at the 100 minute mark for Hope’s (after we stopped adding wood to our second fire).
Elek’s pot (store-bought clay):
| Time after fire started (minutes) | Temperature of pot (℃) |
| 20 | 24 ℃ |
| 25 | 14.8 ℃ |
| 30 | 166.4 ℃ |
| 35 | 152.9 ℃ |
| 40 | 194.9 ℃ |
| 45 | 209 ℃ |
| 50 | 197 ℃ |
| 55 | 204.8 ℃ |
Gisele’s pot (Arb clay):
| Time after fire started (minutes) | Temperature of pot (℃) |
| 20 | 21 ℃ |
| 25 | 18.2 ℃ |
| 30 | 156.3 ℃ |
| 35 | 182.3 ℃ |
| 40 | 165 ℃ |
| 45 | 190 ℃ |
| 50 | 215 ℃ |
| 55 | 208 ℃ |
Hope’s pot:
| Time after fire started (minutes) | Temperature of pot (℃) |
| 100 | 852.8 ℃ |
| 105 | 768 ℃ |
| 110 | 774.3 ℃ |
| 115 | 666.4 ℃ |
| 120 | 593.1 ℃ |
| 125 | 604.2 ℃ |
| 130 | 364 ℃ |
| 135 | 376 ℃ |
| 140 | 387 ℃ |
