Reynolds, E. S. The use of lead citrate at high pH as an electron-opaque stain in electron microscopy.
But there is a way to get a lighter effect, and still see the wood grain, by applying a white semi-opaque stain over the present finish.

Then, the slices were treated with Scale solution containing 4 M urea, 10% (mass/volume) glycerol and 0.1% (mass/volume) Triton X-100, for 10 days to clear the tissue and remove opaque background staining (Hama et al., 2011).
Congo red staining of cultures also showed colour change from red to pink-orange for the sessile opaque strains (not shown).
The glass he used was not made opaque by being painted or stained by hand; it was clear and colored industrially, and the metal strips he used to secure the panes were, for the most part, zinc rather than lead.
A, B, C and D meant 4 different kinds of shape-color types for pollen grains after iodine staining: (A) circular, opaque and dark brown-black; (B) circular, opaque or partially transparent and light brown-black; (C) circular, transparent and light yellow; (D) transparent in an irregular shape and light yellow.
Cellular pathology is observed in every major human disease and relies on the ability of histology to detect cellular change in any cell type due to unbiased pan-cellular staining, even in optically opaque tissues.
Add a dark color of stain to a cup of opaque glaze.
Small, diffuse, opaque, paper-white areas and/or presence of brown stains and pitting scattered over at least 25percentt of the buccal surface of maxillary front teeth (canine to canine) were considered signs of fluorosis.
