It's inevitable that someone applies so much glaze it runs onto the shelf.

Based on this "Ceramics Daily" article I've used this kiln wash, but even with three coats of kiln wash with a firing in between glaze still needs a chisel.

50% Alumina Hydrate (melts 3762F) $1.55 per pound or,
40% Glomax (calcined kaolin)
10% Kaolin
0.5% Darvan 811 dispersant for smooth application and defloccuation
0.1% Calcium Chloride to suspend the liquid kiln wash if it is not used immediately after adding water.

Adding more uncalcined kaolin suspends the kiln wash better but results in more cracking.

I've resorted to using a layer of alumina hydrate on top of the kiln wash. Doing this, absolutely no glaze sticks to the shelf. But a thin layer of alumina hydrate gets embedded in the glaze, leaving pieces which run with a grit embedded in the glaze where it ran. My perspective is this is the least damaging way your runny glazed piece can come out of the kiln.

What else could make a better ingredient in kiln wash?

Zirconium Oxide (melts 4919F) costs $30 per pound. (Zircopax is 91% less costly but is zirconium silicate and seems to introduce the same glaze attachment issues silica does).

Boron Nitride (melts 5383F) but costs $66 a pound. BN (which some know as bullet lubricant) is smoother than alumina hydrate. It's available in a powder in particle size, from 1 micron up to 10 micron.

"Warm Glass" fans use Boron Nitride as an aerosol mold release spray on stainless steel molds. But their experience seems to be that BN is only completely effective until 1800F (~^06). After this the glass may stick, because the non-melting boron nitride migrates into the glass when the glass becomes more liquid.

Laguna Clay sells "Lee's Super Expensive Kiln Wash" with a wetting agent (aka a detergent or more likely propylene glycol which provides a syrupy flow)

Lee's kiln wash also contains a "space age ingredient". I assume this has to be something like boron nitride or zirconium oxide or something I haven't thought of. But at $30 to $66 a pound Lee's couldn't contain much of either. So maybe the "space age ingredient" is something ordinary like Darvan or something to sinter the refractory materials together.

I'm tempted to spend $40 on a gallon of Lee's kiln wash just so I have a reference to compare my kiln wash recipe with it.

The only other solution I can think of are stilts. Ceramic stilts with metal points are $3 each, not really designed for ^6 firings, and become a one-time use product if too much glaze runs.

Ceramic stilts are not much cheaper at $1.25 each.

Does anyone have any better idea
