You canât really exchange any non-gluten flour cup-for-cup with wheat-based all-purpose flour, because every gluten-free flour has a different weight per cup. The most accurate way to measure dry ingredients in baking (and is always the method used in professional bakeries) is by weight not volume. Buy a kitchen scale.
In general, both porcelain and ceramic tile are called âceramic tileâ. These tiles are divided into two groups: Non-porcelain tiles and porcelain tiles. The non-porcelain tiles are referred to as ceramic tiles by themselves, separate from porcelain tiles.
Being a natural stone, Travertine is extremely durable compared to most other flooring types (wood, vinyl, etc), and more than marble and slate. The durability of a porcelain tile is classified according to the PEI Rating, which is the durability index of porcelain and ceramic, and spans between 1-5 (higher PEI = more durable). E.g, Class 3 and above would suit both wall cladding and residential flooring. PEI-high porcelain would be more durable than Travertine.
