My Advice:
The term "Teelichtglas Haymann" or "teelichglas Sandra Rich" you'll find the perfect matching tealight glasses here on Amazon. These have below a diameter of 4.5 cm, top 6.5 cm and a height of 4.5 cm. With this I could erziehlen a good result by inlaid into the glass by the distance to the top to reduce a few coins or a reserve tealight her.
For product: for me there is no more beautiful scented candle and in my loft of 65 m2 is on each one of these windows: 2x white, 1x green and 1x red.
The Keramit is almost error-free and extremely easy to clean. There is no discoloration by the flame or the oils. The product looks after cleaning still like new !!!
