They come from a long line of blah blanks - but decided to up their game.
Meet the Marblewoods - Dad, Junior, and Mom.
They chose Fall colors.
Junior aspires to a colorful life and career; steps:
Unexciting blanks turned as usual.
Sanded up to 600 grit.
Wiped clean with denatured alcohol.
Alum applied with a foam brush (recipe: 2 tbs. of alum, stirred into a quart of warm water using a wire whisk), dried overnight; vacuum save the dried blanks if you anticipate > 48 hours delay in order to avoid oxidation/weakening of the alum/mordant).
Make your size/thickened water for the marble painting (recipe: wire whisk-stir 1.5TBS methylcellulose (methocel) + 1 TBS ammonia into 64 oz. warm water, then add 1 tsp of white distilled vinegar to somewhat neutralize the solution; let set over night to debubble).
Carefully drop Golden High Flow acrylic paints onto the size/thickened water with fan brushes or home made brushes (improvisation is a good thing - toothbrushes, whisk broom fibers, etc.).
Rake the colors together slowly with a home made rake (Tpins, balsa wood, dowel, etc.) - stop when you like what you see.
Silicone stopper the top ends of the blanks.
Wiggle the blanks down through your painting.
Clear painting away from the submerged blank to ensure a clean vertical exit from the size.
Pull the blank up and out, then immediately but gently rinse the marbled blanks in clean water.
Rejoice for an instant - but don't rest on your laurels at this early stage in your marbling career.
Hang the blanks up to dry x 24 hours.
Do another marbling if you like, but be sure to re-alum first (referred to as overmarbling by those in the biz) - the trio below was single-marbled.
Return blanks to the lathe - apply CA finish (I used Bob Smith super thin x 3 layers, Bob Smith medium x 2 layers, then 1 more layer of super thin, followed by Novus 3, then Hut Ultra Gloss plastic polish).
Assemble, rejoice very briefly, but don't disturb the other animals or scare the other blanks:
Happy Saturday to all - Bob
PS: I know that some are awaiting the sand marbling mini-tute - but I've just come up with a few more ideas - fun ahead.
