שריפת הביסק נעשית בתנור הקרמי.

Because שריפת is the construct form of שריפה.

In Hebrew, when one noun is linked to another noun to mean X of Y, the first noun often changes form. That structure is called the construct state or סמיכות.

So:

• שריפה = burning / firing
• שריפת הביסק = the firing of the bisque / the bisque firing

The final -ת is a very common sign that a feminine noun has gone into the construct form.

In a construct chain, definiteness is usually determined by the last noun, not by the first one.

So in:

• שריפת הביסק

the second noun, הביסק, is definite because it has ה־. That makes the whole phrase definite: the bisque firing.

This is different from English, where we usually mark definiteness only once with the, but the logic is similar: the whole unit is definite because its ending is definite.

ביסק is a loanword, from the ceramics term bisque. It refers to the first firing of pottery before glazing, or to the ware at that stage.

With ה־, הביסק means the bisque.

Even though it is a borrowed word, Hebrew still treats it like a regular noun, so it can take the definite article just like native Hebrew words do.

נעשית means is done, is carried out, or sometimes takes place, depending on context.

It comes from the verb עשה, meaning to do / to make, in the נפעל pattern, which often gives a passive or passive-like meaning.

So:

• עושה = does / makes
• נעשית = is done / is made

In this sentence, it gives a technical, descriptive tone: the process is done in a certain place.

Because the subject is שריפת הביסק, and the head noun there is שריפת, which comes from שריפה, a feminine singular noun.

In Hebrew, present-tense verb forms agree with the subject in gender and number. So:

• feminine singular subject → נעשית
• masculine singular subject → נעשה

Since שריפה is feminine, the sentence uses נעשית.

Because the preposition ב־ meaning in attaches directly to the noun.

So:

• ב = in
• תנור = oven / kiln
• בתנור = in an oven / in the oven / in a kiln, depending on context

Hebrew commonly joins short prepositions like ב־, ל־, and כ־ directly to the following word.

Here it means in the ceramic kiln, so it is definite.

A useful thing to know is that in unpointed Hebrew spelling, בתנור can represent either:

• be-tanur = in an oven / kiln
• ba-tanur = in the oven / kiln

The spelling looks the same without vowels. In this sentence, the following adjective הקרמי shows that the noun phrase is definite, so the intended reading is in the ceramic kiln.

Because in Hebrew, adjectives normally come after the noun they describe.

So:

• תנור קרמי = a ceramic kiln
• התנור הקרמי / בתנור הקרמי = the ceramic kiln / in the ceramic kiln

This is the normal Hebrew order:

• noun first
• adjective second

That is different from English, where adjectives usually come before the noun.

Because Hebrew adjectives must agree with the noun in:

• gender
• number
• definiteness

So if the noun is definite, the adjective must also be definite.

Here:

• תנור is masculine singular
• the phrase is definite
• so the adjective is הקרמי: masculine singular definite

That is why Hebrew says, literally, something like in-the-kiln the-ceramic.

It is passive-like, yes.

נעשית literally means is done, so the sentence does not say who performs the action. It focuses on the process itself. That is very common in technical, instructional, and formal writing.

An active version could be something like:

• עושים את שריפת הביסק בתנור הקרמי
• מבצעים את שריפת הביסק בתנור הקרמי

Those mean they do / carry out the bisque firing in the ceramic kiln, but the original sounds more formal and impersonal.

Yes. Hebrew could say something like:

• השריפה של הביסק

But that sounds less compact and usually less formal or technical than שריפת הביסק.

In many technical or written contexts, Hebrew prefers the construct form because it is tighter and more natural for this kind of noun phrase.

It can mean both, depending on context.

In general Hebrew, שריפה often means burning or fire. But in ceramics, metallurgy, and similar fields, it can also mean firing.

In this sentence, the words ביסק and תנור הקרמי make the ceramic meaning clear, so שריפת הביסק is understood as bisque firing, not accidental burning.
