I have been asked to make a matched set of Salt & Pepper Grinder, Lazy Susan and Chopping Block from Jacaranda Timber and I will be finishing them with some sort of Varnish so it really brings out the grain (except the cutting surface of the chopping block).
I need help with what type of Sealer and what type of Varnish /final coat I should use that will keep the Jacaranda as white as possible and because of the shape of the Grinders I want to be able to spray the final coat so I avoid any brush marks.
The Sealers, Varnishes / Estapol / Epoxy's I've used in the past all have a natural honey /yellow tone to them that you don't notice untill you use them on white wood.
Any hints on what is the best Oil or Treatment for the cutting surface on the chopping block would also be appreciated.

Cheer to all and keep the chips flying. I know I will be more now the warmer days are here.

I'd use a water base poly, it doesn't seem to yellow.
Perhaps a tad of white colour in the clear finish may also help.

White Shellac or nitro-cellulose sanding sealer, topped by wax on the Lazy Susan and grinders.

That said, the UV is going to yellow the timber somewhat anyway.

Added: chopping block ... leave as is or use Parrafin oil.

Edit: on reflection, leave the wax off the Lazy Susan and use Hard White shellac if Ubeaut still make it.

the nc sanding sealer yellows over time

Thanks Bob. Independently of the effect of UV?

dunno about uv levels but it yellows on furniture.

Fair 'nuff.

I only use it with wax over the top for turnings out of Huon, Celery Top and the like. They darken with exposure to light like many timbers but I've not done a comparison of treated and untreated.

But Woodnstuff, bottom line is steer clear of oil finishes if you don't want darkening.

Do You have access to a panel beater/spray painting business?

All clears used on cars are water clear and UV protected.

You can get either an acrylc lacquers or a 2 pack clears similar to estapol.

These finishes are far superior to those sold in hardware stores for household use.

Depending on you pocket its also possible to get a ceramic clear which is extremely hard giving great scratch resistance.

I think you will find posts on chopping board finishes if you do a search but there was a test shown onTV a while ago which showed timber if left with no treatment of any kind will be the most hygenic surface for use. Its hard for germs to breed etc if there is no medium for them to grow in.
