Product Information
Black Glassline Pen for glass fusing applications. 

Black is the ultimate 'must have' when it comes to lining and shading your pieces.

They are simple in design, easy to use and can be thinned with water.

Use with the tip set for accurate drawing and writing, or simply use exactly like paints, applying with a brush.

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.

Compatible with all most types of glass including float, CoE90 and CoE96.  Glassline pens fire to a full fuse temperature of 790ºC to 820ºC.

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!

This review is from a user of a microwave kiln. Now I know there are differences between kiln kilns and microwave kilns but I love mine and am always trying to find new things to use with it.
This one however didn't really work as well as I would have liked but in their defence, glassline pens do NOT say they will work in microwave kilns (ok they don't say they don't work either but you get my meaning lol)
What I have found is the ink bubbles up upon fusing, I have tried very long and slow fusing and it still bubbles up. Now it isn't terrible, if you write your name for example and the blackness bubbles up it is still readable and looks very effective. However, I wanted it to draw specific bold geometric shapes for customer requests and I wasn't able to fulfil this to a satisfactory conclusion.
So, 4 stars from me, because it does work and it has so much potential even in a microwave kiln lol
