Additional Setup:

During etching, the solution needs to be warmed to around 35°C. A simple off-the-shelf desktop lamp with a halogen light blub is all it needs. No expensive heat elements is required. You can buy those in most local hardware store. 

Desktop lamp and halogen light blub is sold separately, not included in our product offering.
