UGC Medium - 4oz

Mix the powdered UGC colour with this Medium on a 1:1 ratio then add a drop or two of water if necessary so they are the consistency of "heavy cream" or "melted ice cream". Colours can be mixed and stored in an airtight jar. Some of the colours will settle faster than others, so all must be stirred well before use again. There is a wide variation in how the colours settle.

A note on the Artisan colours: When using to create "lines" of colour with a brush, make the consistency a bit thicker so the lines of colour stay in place easier and don't spread out.

For Artisans you will notice that each colour mixes up a bit differently. Thinner application will give a more translucent colour and smaller bubble and a heavier application will have stronger colour and larger bubbles - but each colour has its own size bubbles!

To apply colours for the most solid coverage - you need to "puddle, push and pull". Use a small liner brush for small areas and a small round for other areas. Pick up colour and drop a small "puddle" of colour to your surface, then "push" and "pull" the puddle to apply. Add another puddle, push and pull until you have filled your area with colour. DO NOT BRUSH THE COLOUR OUT OR "PAINT" IT ON UNLESS YOU WANT STREAKS IN YOUR COLOUR! IT'S NOT PAINT! A thin application will result in streaky colour after firing. You should not be abl eto see through the wet colour. Look at your work from underneath the glassas what you see there is how it will fire. If you make a mistake, let the colour dry and scrape off with a toothpick and brush off the chips and dust created with a soft bruch and re-do the area.

To shade or highlight with colours, you need to "pat, wiggle and muddle" - apply colours side by side and blend bu using the tip of the brush to pat or wiggle between the colours to blend. To "muddle" push the colour around with a larger brush in a more random free-flowing manner.

To apply colours for a watercolour look - Leave water in your brush so the colours become thinned as you apply them to your surface. Tilt your glass so the colours run down your glass and/or run together. Note that colours will not be as strong as extra thinning has taken place. Be careful not to thin too much or you will have weak or no colour. Test, test, test!!

When applying colour and it is "beading up" on your glass - rub over the area with a toothpick and reapply the colour. "Beading/Crawling" (colour pulls in on itself or forms separate beads of colour) as you apply the colour. This may be caused by the surface not being properly cleaned, or oil left behind in a fingerprint.

LET COLOUR DRY COMPLETELY BEFORE FIRING.

Preparing the Glass:

There are many ways to clean your glass, here are two UGC recommend:

A) Scrub both sides of the glass with a powdered abrasive cleanser and a green grit pad. Dry thoroughly. Make a brushstroke of just clean water on each side - the side that beads up most is the "tinned" side and should not be used for the colours. It won't hurt the colours, you just have to rub over the area with a wooden toothpick and the colours lay right down - it's just a nusiance to have to do that!

B) Use very hot water and a hard bristled scrub brush.

DO NOT USE RUBBING ALCOHOL OR GLASS CLEANERS as they may contain oils and/or silicone and will cause the colour to crawl and bead up.
