They are as good as or better than any bowl I've used over the years. You need very hot water, but not boiling water, so 140-150 degrees will do. Leave on briefly, then place in mouth to shape, repeat until shape is right. I use hot tap water and fill the glass 3/4 full, adding ONE part to the water. While it's there, I boil the water in the kettle, then fill up the glass and stir with the tray. This will bring the already hot sheet to the right temperature for forming. Doing this 2 or 3 times at a lower temperature will not ruin the tray or burn your mouth. my teeth. That's easy.
