| 1 | To a secondary vessel add phase A, start mixing, add phase B and heat to 80°C. |
| 2 | Add phase C to phase AB, mix well until newly added items are dissolved and then homogenize for 3 minutes. |
| 3 | To the main vessel add phase D, start mixing and add phase E items in order. |
| 4 | When solids of phase E are fully incorporated, heat phase DE to 75°C. |
| 5 | When both phases are homogeneous and at their designated temperatures, slowly add phase ABC to phase DE with prop mixing. |
| 6 | After 5 minutes start cooling batch and when batch is below 50°C add phase F items one by one with mixing. |
| 7 | Add Phase G if the batch is too thin. |
| 8 | Continue mixing until batch is at room temperature, replacing any water lost to evaporation and mixing until smooth. |
