When using an electric griddle or pallet to melt encaustic medium you want to keep it as low as you can so the medium is just melted between 150°F and 200°F – never above 200°F. You don’t want to get to a point where your wax is starting to smoke. You may want to purchase a griddle thermometer so that you can keep an accurate check on the temperature. You may find that temperature isn’t consistent all over the griddle – some spots may be hotter than others. A griddle thermometer will help you keep a check on that. A temperature regulator may be helpful for use with other fusing tools.
