jerikarl Posted February 25, 2016 Report Share Posted February 25, 2016 I have been using Amaco Velvet underglazes with good results to 05. But it does take 3 solid coats and with some colors a 4th. Has anyone used both and if so, how would you report on the quality of one over the other? Also how are they holding up for anyone firing to mid range? Thanks...jeri Link to comment Share on other sites More sharing options...
oldlady Posted February 26, 2016 Report Share Posted February 26, 2016 well, velvets were made to be used at cone 06 with 3 coats. some of them will go to cone 6 with 3 coats. some will even go to cone 10 with 3 coats. i do not see a reason to complain. I do not use speedball. Link to comment Share on other sites More sharing options...

We use tons of Speedball underglaze, and for the most part they hold up very well at cone 6. A couple of colors like the red and the royal blue tend to melt out a little bit bubble up the glaze, so aren't great for covering large areas, but work fine for details. The rest of the colors we use cover well with two coats and hold color at cone 6. Plus they're a lot cheaper than Amaco, especially if you wait for Clay-King.com to put them on sale. Plus they come pretty thick, so you can thin them down by almost half, which get their prices down to about 3-4 dollars a pint on sale. Link to comment Share on other sites More sharing options...
MatthewV Posted February 26, 2016 Report Share Posted February 26, 2016 I've always used one to two coats. I use the brush to dab instead of stroking though. I also shamelessly mix my brush across all the colors when I work with underglazes. Link to comment Share on other sites More sharing options...
Roberta12 Posted February 26, 2016 Report Share Posted February 26, 2016 I haven't tried Speedball, but I will now after these comments. I have been using Duncan and Amaco with success to cone 6. No problems. Although I did just purchase a Rose color in Amaco and a wine color in Duncan that seem a bit faded out compared to the other colors I have. I am chalking that up to operator error.

Roberta Warm colors- reds, yellows, oranges- sometimes burn out at cone 6. Link to comment Share on other sites More sharing options...
Pugaboo Posted February 27, 2016 Report Share Posted February 27, 2016 Amaco LUG maroon and rose tend to burn out at cone 6. I am testing the Amaco Velvets and waiting for the next kiln load to fire a couple more test panels. So far the maroon here seems to burn out a bit as well but not as badly as the LUG Maroon. The next brand I want to play with is the Mayco Stroke and Coats. I'll have to remember the Speedball brand as well. T Link to comment Share on other sites More sharing options...
Min Posted February 27, 2016 Report Share Posted February 27, 2016 If the colours are burning out try a brand that uses a cadmium inclusion stain for the colour. The Speedball underglazes that contain cadmium are orange, yellow orange, melon, red, burgundy, violet, pink and purple. Some of the non cadmium pink tones do better with a glaze that has a high calcium content. Crysanthos and Spectrum make good underglazes too.
