the joint?

If the joints are close fitting, the solder should flow into
them by capillary action.

Hi,

Try anti-flux painted in a ring around the joints.

Do kilns have “hot spots?”

Hi,

In-furnace soldering is a technique used extensively in
dentistry. Once porcelain is applied to a restoration, direct
flame soldering will ruin the ceramic so many techs
in-furnace(kiln) solder. The pieces are joined in position with
sticky wax(burns out clean) or Duraly( a dental acrylic made for
casting small inlays in the direct mouth-to oven-to cast-to
mouth technique). It is invested in soldering investment and
when the joint area is burned clean, the liberally flux-coated
solder is placed carefully and the piece is slowly brought up to
temp of solder flow. Don’t rush it. If solder refuses to
flow, a gentle tap with small metal tool on the investment
will usually usually do the trick.

The Duralay which I mentioned is a marvelous product. It is a
powder (polymer) /liquid (monomer) that when mixed together will
produce a hard acrylic that can be used to make small parts
(carved with burrs, or when impressed and used as a mold can be
waxed into). It burns out clean at 1000 F. Any body wanting
more info can E-mail me.
