I used Randy's Red successfully for several years--I got the recipe out =
of Ceramics Monthly suggestion column which claimed that it was good for =
refiring over other glazes and was best when applied thick-thin. It was =
listed as a cone 5-6. The reciipe was as follows:
Ger Borate 31.69
talc 13.86
flint 29.7
kona f-4 spar 19.8
epk 4.95
RIO 15

I found that it was best (reddest) when applied thick, it broke black =
over incising, and that unrelieved RR was usually pretty flat. The =
color was best for me closer to cone 5 than 6. Black where thin. It =
was best, and sometimes quite spectacular when used with other glazes: =
an overspray of rutile/neph syn produces beautiful gold highlights; in =
combination with "electic blue" (a real dark cobalt glaze) produces =
golds and blues and iron reds; and with "honey amber" (a transparent =
runny iron-mn) some interesting effects. Definitely best over a dark =
clay. Muddy with copper glazes, interesting with some whites and other =
tans etc,,,, I found it to be a dependable glaze (I don't recall =
pitting or crazing or crawling or any of those things) As I recall, it =
pretty much stayed where you put it. I do a lot spraying and RR was =
useful in shading those hanging leaves and leaf bowls in fall colors. =
Could be successfully brushed. As the CM suggestion said, it was worth =
dumping on things that hadn't turned out the way you thought they should =
to refire--of course when the results were really nice, they proably =
were so totally serendipitous that they could never be repeated!! I =
hope this adds to the Randy's red discussion.
Kay in beautiful Grass Lake Michigan where opening the bisque kiln last =
night revealed several exploded pieces--I guess they weren't as dry as I =
thought! Sure cut down on the leaf lady's inventory for Howard Alan's =
Worthington (Columbus OH) show this weekend--anybody out there going to =
be there? =20
