The pens may be applied between multiple layers of glass or on the top surface for a complex dimensional look.

The pens may also be sprayed to create subtle shading variations.

Glassline paints are lead free and food safe.

Not a true black

Very reasonable price for the quantity in the bottle, and it is super easy to apply, when used with the tip kit. But I was very disappointed with the colour, after firing on full fuse. It was a flat dark grey. I wanted to put in fine detail on my pieces and wanted it to be compatible against the black elements of glass in the piece. I'm now looking for an alternative pen type.

I found this product really easy to use. I bought several colours and have used them to produce detailed paintings.

I love the fact that the colours can be mixed together to create totally unique shades and work.

I suggest buying a tip kit if you want detailed work.

Highly recommended

Very good consistency and opacity. Can be applied very well with the paint cannulas.

I really enjoyed this, and it works well in my microwave kiln.

Black is the most used colour in my collection of Glassline pens. I use it to personalise my glasswork with names and phrases etc to meet bespoke orders. Once dried to grey I can scrape out areas or clean up outlines using a cocktail stick (and a lot of patience!). Over time you may find the bottle clogs up or the glassline is too thick. Firstly try standing the bottle in warm water for a few minutes then shake. But if that still doesn't work just add a few drops of water into the bottle, give the Glassline a very good shake and it will revitalise the product without fading the black after kilning. Not too much water though!
