I don't like using playground-grade sand; the impurities tend to flux it to
the shelf.
(I use fine grog under my work to reduce the friction during shrinkage,
since my
work can be quite heavy. I used to use sand, but quit for the reason
mentioned.)
Pure silica sand is not as bad, but I prefer good old kilnwash for drip
protection.

Unfortunately it has Gerstley Borate, if you don't have any
it will need some conversion.

As an Iron saturate glaze it varies quite a bit according to
thickness.
One quick dip one color, two dips a different color and
three dips still different.
It's in the reddish range you are talking about I think, and
I like the variations.

Hello, "Mudpuppy"
I'm a nurse, too. Well--I was. Finally had to put my license on inactive
status because here, you have to work a certain number of hours to maintain
it. Making pots is more fun and less stress. Anyway, I don't have a
paprika-colored matte glaze, but here's a glossy one that's kind of
paprika-ish.

Yes, it contains the dreaded GB (That's gerstley borate, for all you
Britishers out there). I have plenty, having stocked up, but I'm sure you
could make this work with one of the subs. It's a beautiful red glaze. Must
cool slowly, or you can re-fire it in a bisque load to bring out the red
color.
I suspect talc (or in some glazes, dolomite) is the magic ingredient. One of
the two has been in every iron red glaze I've ever tried. Talc is less
likely to cause pin-holes than dolomite, though, so I prefer it.
Now, about using silica sand on your shelves . . . I do this, but it isn't
going to catch any drips. If you're trying new glazes, fire your first few
pieces on a shard of bisque ware or a bit of a broken kiln shelf. If you do
get drips, grind them off with an angle grinder, masonry disk. (Mask,
gloves, safety glasses) Use the silica sand to keep your pieces from losing
chips off their bottoms during the glaze firing.
You have to be careful with silica sand. It will make its way into your
bowls and plates if you give it any chance at all. Close the peep holes on
your kiln as soon as any organics (like wax) have burned off. The air flow
will stir the sand up, and no matter how careful you were during loading,
it'll land where you don't want it. I'm speculating, but if you're using a
venting system, I don't think you're going to be happy with silica sand. My
kiln is away from the house, so I don't have to worry about that.
Well, talk to you later,

Mudpuppy,
You surely have a favorite white glaze. I suggest that you add 6 /7
percent of a rust colored stain to it to get the color you want.
I coat one side of my kiln shelves with kiln wash. I flip my shelves
over for a bisque firing,thus I only have the kiln washed shelves sides up
during the glaze firing.This is to catch any glaze drips and also helps to
keep the shelves from warping . I always use silica sand on which to place
the ware. The sand acts like ball bearings, and thus prevents any cracking
of clay bottoms.
After a firing I just brush the sand off to save in a container for the
next firing. Hope this helps, Mia in ABQ

Search the archives for a glaze called "Falls Creek Shino." It's cone 6, and if
you apply it reletively thin it comes out a lovely variegated rust color, and it
loves texture. It isn't overly glossy in my estimation, and if applied thicker it
becomes a warm creamy color.
Good luck!
